3 Important Settings in SAP AFS Production Planning.

1. Expand Scope of Check for AFS

IMG Path: Production -> Shop Floor Control -> Operations -> Availability Check -> Expand Scope Check at AFS

Activity Importance : Critical Activity

Here you can make additional settings for the control of the availability check (ATP). You can make AFS-specific settings for each combination of check group and checking rule within the ATP.

Checking rule for the availability check

Use 1:

This rule defines the checking procedure to be used for the availability check (or in Inventory Management, the missing parts check) in individual applications.

Use 2:

It defines, together with the checking group, the different MRP elements that make up this key figure in Flexible Planning.

Brief Explanation...

The whole purpose of this settings is to determine the type of availability check that the system needs to carry out and based on what criteria, if for example is we are to do an availability check for receipts of materials, then we can define the settings such that the system checks if the availability of the material comes from production orders or from purchase order, and as for issues, when checking the availability we can define if for example the sales order and dependant requirements are taken into account during the check.

2. Define General AFS Specific Control Parameters

IMG Path: Production - > Material Requirement planning -> Plant Parameters -> Define General AFS Specific Control Parameters

Activity Importance : Critical Activity

In this section you can carry out general, MRP-relevant settings for a plant.

Activities to be done:

Restrict the number ranges for planned orders, purchase requisitions, and planned independent requirements. Specify the SKU horizon and determine the pegging logic.

Brief Explanation...

Once the MRP is run, this creates purchase requisitions or planned orders for the planned order requirements, and the number ranges for planned orders, purchase requisitions, and planned independent requirements can be setup in this setting.

3. Define MRP Modules to Control Category Assignment (AFS)

IMG Path: Production - > Material Requirement Planning -> Planning -> Define MRP Modules to Control Category Assignment (AFS)

Activity Importance : Critical Activity

In this section you define the MRP modules you use in maintaining the category assignment during the planning run. The MRP module is used for the assignment of stock categories to requirements categories.

Example

Module M1 means that the entire stock, all purchase requisitions, and purchase orders that are available for the customer's requested delivery date, are used to satisfy the existing requirements (FIFO - first in first out).

In the configuration you would need to setup the MRP Module and the relevant function module for this.

Brief Explanation....

The MRP module controls the assignment of the requirement categories to the stock categories. Module M1 uses a strategy where all batches of stock, purchase requisitions and purchase orders which are available on the requested delivery date (sales order) and assigned to the stock category, will be used to satisfy the requirement.

It is important that you have a clear idea of the function module in order to specify the setting for this MRP Module.

Hope you found the above post useful. I shall update more posts such as this in the future.

Have a nice day.
