Plant Parameters
Configuring the SAP R/3 system for production is one of the most challenging tasks in R/3 configuration CO will not be configured for production in this
exercise Configuring the CO module to accurately track
manufacturing costs is extremely challengingRequires balance between accurate cost
allocations and data collection requirements. To much detail can make the SAP system difficult to use, which means it is not likely to be used correctly.

Planning vs. Scheduling
Configuring the production planning (PP) module is complicated by the fact that planning and scheduling are two separate, but highly related, activities.
Planning, typically implemented via Material Requirements Planning (MRP), is used to create planned orders and purchase requisitions—suggestions by the SAP system as to what should be produced on the shop floor or procured from suppliers (vendors), respectively.

Planning vs. Scheduling
Scheduling is the process of converting planned orders into production orders and purchase requisitions into purchase orders, then managing these orders in detail.

Floats
In both planning and scheduling, floats can be added to planning times to provide for a buffer against uncertainty. The production lead time for a material might be 12 days. Of that 12 days, 10 days might be the expected production time with a float of 2 days added to allow for production disruptions.
Floats are organized in the SAP R/3 system using Schedule Margin Keys.
![Page 6: Module 10 Setup for Production. Plant Parameters Configuring the SAP R/3 system for production is one of the most challenging tasks in R/3 configuration.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649d805503460f94a64133/html5/thumbnails/6.jpg)
Floats
Four floats are defined in a schedule/margin key: Opening period: Workdays prior to order start. Float Before Production: Workdays between order
start and scheduled start. Float after Production: Workdays between order
due date and scheduled finish date. Release Period: Workdays in release period.

MRP
Planning, which is done by the MRP process, needs: In-house production time GR processing time Opening Period
The MRP process will determine the order start and order finish date, as well as the planned opening date
The planned opening date can be used by planners to convert planned orders to production orders by groups rather than individually. The MRP planner can convert groups of planned orders based on the planned opening date.

![Page 12: Module 10 Setup for Production. Plant Parameters Configuring the SAP R/3 system for production is one of the most challenging tasks in R/3 configuration.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649d805503460f94a64133/html5/thumbnails/12.jpg)
The float before production and float are used to calculated the scheduled start and scheduled finish dates when the planned order is converted into a production order.
The float before production is a start float. It has two functions: It can compensate for delays in the staging of the material components. If there is a capacity bottleneck at the work
centers involved, the production dates can be moved forward in the future. In this way it
serves as a float for capacity leveling.
Production Order Scheduling
![Page 13: Module 10 Setup for Production. Plant Parameters Configuring the SAP R/3 system for production is one of the most challenging tasks in R/3 configuration.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649d805503460f94a64133/html5/thumbnails/13.jpg)
The float after production is a finish float. It is used to compensate for unexpected disturbances in the production process, so that they do not delay the scheduled finish date.
The system calculates the scheduled start of the order by adding the float before production to the order start date. It calculates the scheduled finish of the order by subtracting the float after production from the order finish date.
Production Order Scheduling
![Page 14: Module 10 Setup for Production. Plant Parameters Configuring the SAP R/3 system for production is one of the most challenging tasks in R/3 configuration.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649d805503460f94a64133/html5/thumbnails/14.jpg)

Note how the float before production and float after production are used to calculate the scheduled start and scheduled finish time. The in-house production time specified on the MRP 2 View of the material master should be the sum of the expected processing time plus the float before production plus the float after production.
Production Order Scheduling
![Page 16: Module 10 Setup for Production. Plant Parameters Configuring the SAP R/3 system for production is one of the most challenging tasks in R/3 configuration.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649d805503460f94a64133/html5/thumbnails/16.jpg)
Release Period
The SAP system can be configured so that a production order is released as soon as it is created. This means that the production facility can begin production.
The SAP system can also be configured to make the release of the production order a separate step. In this case, the SAP system deducts the number of days defined in the release period from the scheduled start of the order to determine the scheduled release date of the order. This date can be used by the production scheduler to perform collective release, i.e., release a group of production orders based on the scheduled release date.
![Page 17: Module 10 Setup for Production. Plant Parameters Configuring the SAP R/3 system for production is one of the most challenging tasks in R/3 configuration.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649d805503460f94a64133/html5/thumbnails/17.jpg)
Number Ranges
Every transaction in SAP is numbered. Some companies are very interested in the format of numbers assigned to different objects. The SAP R/3 system gives the user the ability to define different number ranges (number of digits, numeric or alphanumeric, starting number, etc.) and then assign them to different objects.
![Page 18: Module 10 Setup for Production. Plant Parameters Configuring the SAP R/3 system for production is one of the most challenging tasks in R/3 configuration.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649d805503460f94a64133/html5/thumbnails/18.jpg)
Number Ranges
In defining plant parameters, number ranges must be defined and assigned to: Planned orders Reservations/Dependent requirements Purchase requisitions MRP lists Simulated dependent requirement
![Page 19: Module 10 Setup for Production. Plant Parameters Configuring the SAP R/3 system for production is one of the most challenging tasks in R/3 configuration.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649d805503460f94a64133/html5/thumbnails/19.jpg)
MRP Controllers
In the SAP system, the person designated to manage the production and inventory levels for a material is called the MRP Controller.
Each material can be assigned to a particular MRP Controller.
The MRP Controller is used to select materials for reports like the Stock/requirements list.
The Stock/requirements list, is an interactive transaction for managing the production and inventory levels for a material
![Page 20: Module 10 Setup for Production. Plant Parameters Configuring the SAP R/3 system for production is one of the most challenging tasks in R/3 configuration.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649d805503460f94a64133/html5/thumbnails/20.jpg)
Production Scheduling Profile
The production scheduling profile determines how production scheduling is to be carried out in the plant. Settings in the production scheduling profile control things like: When production orders are released for
production (upon creation, for example). When production orders are scheduled (on
release, for example).
![Page 21: Module 10 Setup for Production. Plant Parameters Configuring the SAP R/3 system for production is one of the most challenging tasks in R/3 configuration.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649d805503460f94a64133/html5/thumbnails/21.jpg)
Production Scheduler
Similar to the MRP Controller, a Production Scheduler must be defined in the SAP system to control detailed production scheduling for a material. A production scheduling profile is assigned to the Production Scheduler, and the Production Schedule is defined in the Work Scheduling view of the Material Master.
![Page 22: Module 10 Setup for Production. Plant Parameters Configuring the SAP R/3 system for production is one of the most challenging tasks in R/3 configuration.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649d805503460f94a64133/html5/thumbnails/22.jpg)
Material Availability Check
When the MRP system creates a planned order, it can also check whether the components and sub-assemblies required to complete the planned order will be available.
![Page 23: Module 10 Setup for Production. Plant Parameters Configuring the SAP R/3 system for production is one of the most challenging tasks in R/3 configuration.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649d805503460f94a64133/html5/thumbnails/23.jpg)
Bill of Material
The Bill of Material (BOM) defines the relationship between materials that make up an assembled product:
It is the “recipe” for
a material

Routings
Routings define the relationship between a material and the sequence of workcenters (operations) that are required to produce the material. Routings determine: The operations (work steps) to be carried out during
production of a material The activities to be performed in the operations as a
basis for determining dates (start, finish, available, etc.), capacity requirements, and costs for a production order
The use of materials during production The use of work centers The quality checks to be carried out during
production
![Page 25: Module 10 Setup for Production. Plant Parameters Configuring the SAP R/3 system for production is one of the most challenging tasks in R/3 configuration.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649d805503460f94a64133/html5/thumbnails/25.jpg)
BOM and Routing Selection ID
Different routings and BOMs may be defined for a material. These routings may be applicable for different production quantities, for example. When products change, the BOM and/or routing may change, so BOMs and routings can have validity periods to define when the changes occur.
BOM and Routing Selection IDs determine how the SAP system will find the correct BOM and routing for a production order.
![Page 26: Module 10 Setup for Production. Plant Parameters Configuring the SAP R/3 system for production is one of the most challenging tasks in R/3 configuration.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649d805503460f94a64133/html5/thumbnails/26.jpg)
BOM and Routing Selection ID
With the routing selection ID 01, when an order is created, the system looks for a routing that is valid for the date the production order is being created and the lot size of the production order. If more than one routing is valid for a production order, the SAP system selects the first valid routing.
Similarly, with BOM selection ID 01, the system looks for a BOM for the material with the correct status (active), lot size and validity date.

Planning Horizon
The planning horizon (measured in days) determines how far in the future the MRP planning process looks to create production orders.
A production scheduler can structure the MRP process to create production orders for all demand (forecast demand, customer orders) recorded in the system, or only that demand that is within the number of days in the planning horizon into the future.
![Page 29: Module 10 Setup for Production. Plant Parameters Configuring the SAP R/3 system for production is one of the most challenging tasks in R/3 configuration.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649d805503460f94a64133/html5/thumbnails/29.jpg)
Production Order Availability Checks
For standard production order type PP01, availability checks can be specified on a plant-by-plant basis.
Availability checks can be performed for: Materials: availability of component materials Production Resources and Tools (PRT) Production Capacity
Checks can be specified to be determined when a production order is created, a production order is released, or both times.
![Page 30: Module 10 Setup for Production. Plant Parameters Configuring the SAP R/3 system for production is one of the most challenging tasks in R/3 configuration.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649d805503460f94a64133/html5/thumbnails/30.jpg)
Production Order Availability Checks
If availability checks are specified, then production orders cannot be created if the availability check is not passed.
For example, if a material availability check is specified at order creation, then a production order for a batch of snack bar dough cannot be created unless all raw materials (oats, wheat germ, cinnamon, etc. are in stock in sufficient quantities. ## Dough NRG–A

Forward and Backward Scheduling
Two basic methods of production order scheduling are available Forward Scheduling, where a production
order is scheduled to start immediately and finish as soon as possible
Backward Scheduling, where the scheduling begins at the due date and works backward.Most students use backward schedulingBackward scheduling can lead to
problems if there is not enough float time in the schedule to account for disruptions

Material Master Views for Production
The MRP views in the Material Master define a range of parameters for planning.
There are four MRP views (MRP 1, MRP 2, MRP 3 and MRP 4) that contain Production Planning Parameters
Production scheduling parameters are entered in the Work Scheduling View

MRP Run
In Single-item, Single-level planning, only the material is planned, not other materials that may be required to make the material
For example, if single-item, single-level planning is used on the dough material, then only the dough is planned and not the materials needed to make dough, like oats, wheat germ, etc.
A number of parameters areset that in MRP planning to determinehow planning is to proceed and whatit is to produce (planned orders vs.purchase requisitions, for example).

Stock/Requirements List
The Stock/requirements list is an interactive report that provides a comprehensive set of information about a material, including inventory, planned orders, forecast demand, customer orders.
In addition, by double-clicking on specific items, the user can access a variety of data like material masters, detailed stock overviews, production order details, etc.
The Stock/requirements list is the primary tool used by planners and schedulers.
