Introduction to ALE

• Application linking and enabling (ALE) is SAP’s technology to support distributed process across several SAP systems.

• A distributed process is one in which part of a business is carried out in one system and part on another.

• A distributed process may contain SAP and non SAP Systems. It is not necessarily between only SAP systems.

• ALE can be used to exchange the data between, SAP to SAP system SAP to Non-SAP system Non SAP to SAP System

Introduction to IDOC

• The term IDOC stands for Intermediate document. It is simply a data container used to exchange information between any two process. That can understand the syntax and semantics of the data.

• IDOC’s are made using the segments

• IDOC’s are stored in the data base

• Every IDOC has unique number

• An IDOC is attached to a message type and identified by its message type

• IDOC consists of three types of records One control record One or many data records One or many status records.

• Control Record:

A control record contains all of the control information about an IDOC, IDOC number Sender and receiver information Message type it represents Its direction

Introduction to IDOC• Data Record In an IDOC the data record contains the application data.

13


• Status Record

Status records are attached to an IDOC throughout the process as the IDOC achieves different milestones or encounter an error. At every milestone a status code, date and time are assigned.

The system defines numerous status code, 0 – 49 are reserved for outbound process 50 and above are reserved for inbound process

Configuring the ALE Infrastructure

• The basic settings for the IDOC interface must be maintained once on each system involved in distributed process

• Basic settings for IDOCs

1. Maintaining logical system

2. Allocating logical system to the client

3. Setting up an RFC destination

4. The port definition

5. Maintain the distribution model

6. Create a partner profile

22


1. Maintaining logical system – Transaction ‘SALE’

3. Setting up an RFC destination – Transaction ‘SM59’

Transaction SM51 to Identify the Target Host of remote system

4. The Port definition – Transaction ‘WE21’

5. Maintaining the distribution model – Transaction ‘BD64’

Creating the new IDOC type

1. IDOC is created using one or more segments. Each segment will have one or more fields. Group functionally related fields into segments. Then use segments to create the IDOC.

2. Release segment type and basic IDOC type

3. Allowed data type for the segments.

CHAR Character strings

CLNT Client

CUKY Currency key, referenced by CURR fields

DATS Date field (YYYYMMDD) stored as char(8)

LANG Language key

NUMC Character fields with only digits

TIMS Time field (HHMMSS) stored as char(6)

34


1. Create the segments – Transaction ‘WE31’

35


2. Create the basic IDOC type Transaction ‘WE30’ step 1

Configuring the system for new IDOC

Configuring the outbound process Create the new message type (WE81) Link the IDOC type to the message type (WE82) Add the message to the ALE distribution model (BD64) Create the partner profile (WE20)

42

Configuring the system for new IDOC

Configuring the inbound process Create the new message type (WE81) Link the IDOC type to the message type (WE82) Allocate the function module to the logical message (WE57) Define the attributes for the inbound function module (BD51) Create new process code (WE42) Assign the process code to the function module (WE42) Create the partner profile (WE20)
