12/2010 to 07/2011ISU/CCS ConsultantClient: TXU Energy (6.7 Million Customers)CRM-ISU Bad Debt Project (CRM 5.0)

CRM & ISU – Enrollment RAID Prior Debt Project


Move in process is redesigned to expand prior debt check on the enrolling business partner. The new enrollment process identifies duplicate business partners of the move-in BP and their prior debt. The move-in BP will be able to accept and pay, or dispute the prior debt.

CRM – Developed custom function module to identify duplicate business partners based on the move-in BP’s driver’s license, social security number, first name, last name, or spouse.

CRM – Developed custom screen to display prior debt of the move-in BP, with prior debt being summarized at the contract level with service address displayed. This improved the CSR’s efficiency in verifying the prior debt with the BP. A hotspot ALV event is implemented to allow the CSR to dispute prior debt at contract level and dynamically recalculates total prior debt.

CRM – Added function to the move in template program to create issue referral transactions during move-in save, end contract, and cancel enrollment when there are disputed items, so that the issue referral team can analyze the disputes.

CRM – Developed new methods in the move-in BADI to create appropriate interaction records with the appropriate description, process type, category, and text with the prior debt line item details.

CRM – Added new attributes to the move-in BADI to save the prior debt details summarized by contracts and prior debt details by line items for more efficient disputed line item look-up.

CRM – Added logic to the move-in function module to set the ID Type -Above Threshold Flag when the BP’s prior debt is above threshold. This flag clears only when all prior debt is paid. This flag prevents the move-in BP from paying only the minimum amount necessary to become prior debt below threshold.

CRM – Added function to move in template program to open the issue referral tab in change mode when an issue referral is created, during move-in save or cancel enrollment, to allow the CSR to enter more detail in the issue referral document.

CRM - Configured the Status Profile for Contract Header for User Status for Prior Debt Above Threshold, so that the appropriate status can be set in the following steps for credit checks.

FICA – Developed custom function module to determine the prior debt of the move-in BP and the duplicate BP’s, which includes past due debt and statistical write off debt.

FICA – Enhanced payment screen logic to automate the accept payment function, so that CSR can enter a total amount and the payment info only once, and the payment program can make the payment to each contract account using the prior debt info. This expedites the payment process, reduces probability for error.

FICA - Transfer of debt process – when the contract is replicated to ISU, a BADI is implemented to transfer the past due line items and statistical write off line items to the move-in BP’s new contract

FICA – Transfer of debt process – before transferring past due debt or statistical write off debt, if the debt line item is submitted to collection agency, implemented event 5065 – Collection Agency Recall Items to set the appropriate recall reason based on calling stack.

FICA – Added logic in move in program to copy creditworthiness from the duplicate BPs to the move-in BP, if they are more recent than the move-in BP’s. This involves calling standard BAPI’s to retrieve the CW score, creating credit record, freezing and unfreezing, and replicating CW to credit profile. This saves the cost of making any unnecessary external calls for credit check.

FICA – Transfer of debt process - modified customized event 5080- Transfer Items: Check validity to allow line items with a blank contract to transfer.

FICA – Transfer of debt process – modified customized event 5120 – Transfer Items: Determine Additional Specification to ensure a valid target contract is populated.

FICA – Transfer of debt process – configured customized event 5130 – Transfer Open Item: Split Criterion to set the split flag and XBLNR flag to ensure the reference doc is populated in target item.

FICA – Developed function module to apply dunning locks on the move-in BP’s contract accounts when the move-in is saved and when there are disputed items, so these accounts do not get dunned due to the items disputed.


FICA – Developed function module to apply payment locks on the move-in BP’s disputed items so that the disputed items do not get paid in payment run.

08/2011 to 12/201103/2010 to 12/2010FICA ConsultantClient: London HydroPost-Implementation Stabilization Project

FICA – Credit and Collections - Disconnection Approval List Redesign Project Disconnection process is redesigned to utilize standard dunning functionality to generate a list

of accounts for disconnection approval, and allow user to perform collection activities. The new solution uses SAP standard logic to generate reminder notices, disconnection

documents, and disconnection orders, and notifications. Workflows are used to create the notifications with the corresponding tasks. The users can then use IW66 to view and perform collection activities on the notification list. IW66 has been customized with custom actions boxes to facilitate the various collection activities, including collection field trips, and disconnections.

Configured dunning procedures, dunning levels, and activities including owners, tenants, commercials, final procedure, and SD accounts.

Configured event 187, when P2P is created, complete all open tasks. Configured event 190, when P2P is closed, check fulfill status and open collection task if

needed. Configured event 301 to determine the dunning procedure based on the contract account’s

normal and move-out dunning procedure, instead of at the contract level. Configured event 304 to determine the next dunning level using the dunning procedure on the

contract account level. Configured event 300 and dunning configuration to ensure inactive accounts are dunned using

the Final Dunning Procedure by Days in Arrears of the last final bill due date. Configured event 0350 to do account class check, credit check, and amount check before

carrying out dunning activity. Created program to remove dunning procedure from contracts, so that they will be dunned and

grouped at contract account level. Created dunning reversal workflow, to close the disconnection document, notification and

tasks, in the case of full payment, dunning reversal or promise-to-pay created. Created move out workflow to trigger dunning reversal workflow when a move out is completed Added custom z fields to notification header table QMEL and screen to show collection details.

FICA- Late Payment Charge Per client, changed logic in LPC Reversal program to create offset item to offset the charge, so

that the invoice does not have to be reversed in order to reverse the charge. This process automates the manual steps so that the CSR efficiency can be improved.

The program first reset clear item, if the source item is already cleared. Then it performs account maintenance to clear the source item and the offset item.

Configured main and sub transactions for the offset items, and to allow program to reverse other charges also.

FICA - AR Aging Report Customized standard report FP07 to evaluate open items dataset generated by FP01 to

classify the aging of the open items. Customized standard report FP07 generated by FP01 to evaluate past due items which have

never been dunned, and classify the aging of the open items.

Ken YeungExperience Continued FICA – Production Support Work

Return for PAP customers. Configured event 295 for return, to remove contract account from PAP if there are 3 NSF returns in the past year.

Promise-to-pay. Developed program to remove dunning lock on account if there is no more outstanding p2p with a future check date on account, so that these accounts can get dunned.

08/2008 to 02/2010IS-U/CCS ConsultantConsulting Firm: Vertex North AmericaClient: Pinellas County Utilities

Web Services Self-Serve Portal Project Conducted requirement gathering session with client to identify information needed on each

self-serve web page, and performed data mapping to SAP table fields. Created Consumption History BAPI called by web service to retrieve one year of consumption

history using installation facts written during invoicing. This approach ensures consistency with the actual paper invoice. It includes information such as consumption month, billed consumption, days of service, meter reading, meter reading date, bill from and to dates.

Created Service Record BAPI to retrieve service address, meter reading and date, and calculate average consumption information.

Created Bill History BAPI to retrieve one year of billing history of contract account. Added logic to retrieve and calculate previous invoice total, last payment received, new current charges, and balance forward. Added the same logic to Account Summary BAPI.

Per client, Bill History page should display a rolling 12 month of history of the same contract account, not from the last move-in date. This is due to some accounts have seasonal turn off. Added logic to select installation facts based on consumption history within one year period for the same contract account.

Created custom table to store service requests. Created Service Request BAPI to allow customer to request disconnect, reconnect, and name change service from the web portal by storing the service type, service reason, date, and updated information.

Created Add Bank Detail BAPI. It adds the Bank Routing Number and Bank Account first to the Business Partner, and then updates CA specified to the BAPI to allow ACH processing. The process calls standard SAP function modules to ensure the proper change records are created.

Created Validate Bank BAPI to validate bank routing number during the process to add bank detail to business partner and contract account for ACH processing.

Added logic to bill prints to assign paperless pull-code if the paperless indicator is set on the contract account. This allows the paper bill printing to be omitted to save costs for client.

Created Remove Bank Detail BAPI for removing automatic payment from the contract account. It clears the incoming payment method and bank id from Contract Account.

Bill Print and FICA – Security Deposit Display Project Bill Print -Deposit Requests.

-Added additional logic to check the start date for Deposit Requests. Only display them if the start date is within the current period, otherwise they have been already included in previous invoice.-If Deposit Request item is cleared during invoice, no need to display the Deposit Request again on current invoice.

Bill Print – Deposit Interest. Added additional logic for security deposit interest line item. Selected items using main/sub of 0025/0010 for deposit interest items within current period based on the ‘Entered On’ Date in header and append to invoice, so that invoice will balance.

Bill Print – Deposit Release during Final Bill.


-Added logic to deduct the open deposit request amount form outstanding amount, since the final bill reverses the open deposit request.-Added condition to select the stat reset item from DFKKOP for the current period, to be sure that there is open deposit amount that is reversed from Outstanding balance-Added logic to ignore previous items with main of 5000 (Other Charges), since previous items are captured in Outstanding Balance.

Bill Print – Deposit Release. -Added logic to manually select the deposit release items from DFKKOP instead of from print doc, in case sometimes the deposit release item is not in the print doc-Added logic to handle the scenario where the clearing date of one of the deposit payment is in the future (not within current period). In this case, we will check the return date of the deposit and use that instead.

Bill Print – Deposit Return.-Changed logic so that do not display the deposit request if it is cleared by statistical reset-Added logic to check deposit status of 04 (paid), for scenario where the return date is within the current period, but the deposit is not refunded, so we do not display the refund line item.-Changed it to look up deposit status using the security nunber, which is the key, as the doc number sometimes returned the wrong deposit.

Bill Print - Deposit Partial release. Added logic to deduct the partial release of deposit from Deposit on Account. We need to use DFKKOP clearing date, because the ‘Partially Returned’ status does not tell us the date it happened.

Bill Print –Deposit Partially Paid. -Added the logic to handle the partially paid/cleared status in the partially paid deposit logic, so that the stat reset item is deducted from outstanding balance.-Added logic to the partially paid/cleared logic, on both the deposit on acct and line item logic, to use the earlier of security start date or the deposit request (0020-0020) clearing date, as this marks the clearing of the deposit.- Added condition to check for Returned (98) deposits to display partial deposit payment, in case of deposit is already returned during invoice display, but is partially cleared during invoice creation.

Bill Print – Reversed Items. -Changed logic to deduct reversed items from Outstanding Balance, and changed Billing Configuration to select all open items, including the ones not yet due, on the invoice. -Changed reversal logic, that we deduct the reversed item from Out. Bal. only if its Entered On Date was (therefore was applied) before the current period, and is reversed in the current period. Maintain custom config table to enable item 0610/0010 for Account Maintenance to display.

Bill Print – First Invoice.-Added logic to not to perform manual select for deposits for first invoice, since all items should be displayed already.-Made change to display migration debit and credit items for first invoice.

Bill Print --Payment on Account Transfer Open Item. The first invoice has a Payment on Account as Transfer Open Item. Therefore added logic to capture this special Payment On Acct case. Added logic to reject the Transfer Open Item from current deposit item, as they are unrelated.

Bill Print - Misc Postings. Added logic for misc postings select, so that only select main of 6000 and within current billing period by entry date, while not capturing the items in the print doc so that we don't double count.

Bill Print -Consumption Display. Meter readings with '16' adjustment reads are being merged into a single read by error. Per PCU, only 2 meter reading records should display on invoice. Made the change to take only the first 16 read, and delete the rest from the picture. And, not to merge the 16 read with the reads after it.

Ken YeungExperience Continued FICA - Municipality Payment Report Project

Developed a municipality payment report to calculate the payments for each municipality. The report lists for a specific date range for activities that occurred on any of the company codes. The activities are grouped into 4 main catagories: 1) Billing 2) Bill Adjustment 3) Payment 4) Write off. The activities are subtotaled by company code, catagory, and business area.

Report was created based on standard SAP report used in transaction FPT3 – Display General Leger transfer total and FPT5 – Itemization report.

The report processes line items based on DFKKOP and categorizes them by the document origin. It uses get cleared items and get formerly cleared items function modules for the various document types and scenarios such as accounting maintenance and reset clearing.

Added logic to count number of contracts for the Billing category. Added totals page break-down based on business area, per PCU client.

Conducted knowledge transfer to the basis team and other FICA consultant regarding the report’s running parameters for daily and monthly batch jobs.

Changed logic in payment processing to flag payment as reconciliation item only if the General Ledger matches the security item cleared.

Changed logic in detecting security deposit release scenario, so that if the deposit is released, the item is not flagged as reconciling item and is included in total payment.

Added logic to include all line items going into the A/R General Ledger in the total calculation, while exclude line items going into the security deposit General Ledger, to ensure the total are reconciled to another report.

Added logic to retrieve consumption for Water and Sewer installations from FICA GL item table DFKKOPK using field MENGE. Added Zero Consumption logic. If the consumption is 0, verify that if the installation is a flat rate only installation by checking the rate category and price category (quantity-based or not) from bill doc line items.

FICA – Security Deposit Report Developed a security deposit report to identify all the security deposits for the current fiscal

year for General Ledger reconciliation. Added logic to handle special scenarios for reversal, account maintenance reset, manual

payment reset, check lot reset, invoicing, and check payment, and payment run using FKK_GET_FORMERLY_CLEARED_ITEMS and FKK_GET_CLEARED_ITEMS function modules by checking the security deposit request flag and the main transaction.

Added security start date and return date to report, and removed service address, as per client PCU.

DM - AMR Project Modified the existing MRO output Application Form for Itron to generate MRO output for

Neptune AMR meter vendor, and tested the MRO output in EL16. Developed the MR download program to create the download file to Neptune based on new

MRO output. Using Object Oriented programming, added logic to count the number of premises and number meters per route using object casting.

Developed the MR upload program to process meter reading uploads per the Neptune AMR vendor’s specification. Tested MR result updating in SAP, and trouble codes, trouble message, skip code, and device location notes and etc updating in SAP.

MR download and upload programs. Updated documentation within programs. Updated logic flow and custom object inventory in functional specification for download and upload.

MRO download. Replaced meter location code '00' by Space to avoid runtime error, per Neptune vendor.

Added logic to use Order Status field and skip records that are Incomplete and has no MR date.


Adopted the exiting meter vendor Itron’s logic in determining account status, since this is the way PCU expected it to work.

Changed the logic in download program for calculating the consumption low and high values based on the sum of previous reading and low and high output from SAP, as per Neptune. Added roll-over checks based on number of dials in meter.

Print Docs mass reversal by transaction EA15 during AMR billing testing. MR Upload. Changed logic in Meter Reading upload program to read trouble code from the

Meter Detail segment instead of the Order Detail segment.

Sustainment and Operation Support FICA –Payment Report. Added logic to sum up total of sub-items to look up the cleared item,

in case there are sub-items. FICA – Write off utility tax process. Changed function module for write off event 5030 to use

division as part of criteria to look up the account assignment config so that the right account assignment is retrieved

FICA – Dunning Activities. Changed logic for custom function modules used for posting fees and trigger disconnection workflow to ensure that the contracts extracted are active.

FICA lien interest calculation. Added logic to lien interest calculation function module to not bill the lien interest when the lien line item is less than zero.

FICA Dunning report. Modified the dunning custom report to ensure the PO Box zip code is extracted properly, and to select the business partner address based on the current mailing address.

FICA Incoming Payment Lot processing. Enhanced the incoming payment lot processing program with the business partner name field, so that the information can be used during clarification worklist research when the account number is not found.

FICA Dunning. Added logic to the Dunning Delinquent Notice form user exit to set the notice due date to payment target deadline in the dunning history header, so that the number of days is in factory calendar, instead of calendar days.

FICA Security Deposit Interest Applied SAP note such that the security deposit interest is not applied to securities that are returned

Billing – Joint Invoicing Process. Created a custom function module for event R403 with the logic that if any of the contracts are set to be joint invoiced, and billing docs cannot be invoiced due to unbillable billing orders, we set all the billing docs as cannot be invoiced.

Billing – Lien Interest billing process. Changed logic in custom program so that the debit item with the correct division is used as template to append the lien interest line item.

Billing – Lien Billing Process. Modified program to exclude security deposit request items from lien calculation, and not calculate lien if installment plan is active per client.

Billing – Conservation Fee Billing Process. Modified function module to not bill conservation fee if 120% value is below the threshold or if the current consumption is below the threshold, per client requirement.

Billing – Lien Interest billing process. Added logic to allow reclaim only and sewer only installations to bill lien interest.

Billing – Conservation fee billing report. Added logic to filter the meter reads by contract move in/out dates to ensure the correct consumption is reported.

Billing – custom tax calculation billing process. Changed logic to bill utility tax up to and including the date of move out for final bills, and stop billing tax after installation is moved out.

Billing – custom report development. Developed custom report to report information needed by client for installations with no active contracts.

Billing. – Custom fee billing process. Added logic in custom program to clear the former values to ensure that the correct values are used for calculating the fee.

Billing. - Custom fee billing process. Modified the conservation fee billing report so that for installations with multiple meters, combine the meter readings on the same date into one for report clarity, per PCU client, and added multiple indicator to report.


Billing. - Custom fee billing process. Modified the conservation fee billing function module to save meter read date info so that the report knows the timestamp of billing calculation results.

Billing. - Custom fee billing process. Modified the conservation fee billing function module so that line items used in calculation are sorted correctly.

Billing. - Custom fee billing process. Modified the conservation fee billing report to handle installations with non-billable reads and single move-reads, such that the consumption can be calculated correctly. Also modified the report to handle meter changed out and meter reading roll-over situations to avoid negative consumptions.

Bill Print - Invoice print process. Changed custom config table for invoice line item display orders to ensure the invoice displays in an order expected by the client.

Bill Print - Invoice print process. Changed logic so that Deposit Request that is not cleared will display as part of Outstanding Balance on the subsequent period, rather as separate line item, per client.

Bill Print - Invoice print process. Added condition to Deposit item logic so each Deposit Payment is deducted only once from Outstanding Balance when it clears the Deposit Request.

Bill Print – Invoice print process. Changed logic on Deposits to only display Deposit On Account amount only if deposit request is cleared in previous or current bill period.

Bill Print – Invoice print process. Added logic to display Deposit Interest items as separate line items, not just as part of the Deposit On Account amount, per client.

Bill Print – Invoice print process. Changed logic in User Exit so that reversed line items and reversed payments are not included as Payment Received, to ensure invoice accuracy.

Bill Print – Invoice print process. Fixed bug with bill print User Exit to truncate commas in amount value so that runtime error does not occur during type conversion.

Bill Print - Invoice print process. Added logic to the retail Form User Exit to ignore proration reads and other interim reads, so that the merging logic can compute the consumptions properly. Added logic to ensure the unit of measure is correct for meter changed out scenarios.
