If you implement Grouping, Pegging, Distribution (GPD) for project-based production procedures, you can use pegging to determine the proportional assignments of replenishment elements (production orders and purchase orders) for a grouping work breakdown structure (WBS) element to the objects that caused the requirements (reservations, planned, independent requirements). These assignments form the basis for the cost distribution that follows and distributes the costs for the procurement elements of grouped requirements to the original projects.

Pegging can be performed in the following ways:

MRP Logic

The assignment of replenishment elements to pegged requirements occurs based on the current requirements planning situation. Previous assignments are not taken into account.

Fixing Rule

During the assignment process, the attempt is made to copy as many assignments as possible for a replenishment element form the previous pegged requirements run. This means that cost transfer postings at a later date can be avoided.

Special rules must be applied for the assignment of exceptions (surplus, scrap and stock differences).

The transactions for pegging and cost distribution are not in the SAP menu. The function can only be released after agreement with SAP. Due to the complexity of GPD, we recommend that you discuss your relevant business processes with an SAP Aerospace and Defense consultant.


Grouped material requirements under one or several grouping WBS elements already exist for the WBS elements

In Customizing, you have done the following:

Assigned a distribution profile to your grouping WBS

Assigned a logic to execute pegging in Customizing under Pegging: General Settings

Under Pegging: General Settings , you have assigned rules to assign exceptions

Maintained the movement types that are allowed for pegging

For more information, in Customizing, choose LogisticsProject SystemCostsAutomatic and Periodic AllocationsPegging

To use a cost structure that deviates form the production structure, you have created break points .

You have created special WBS elements to assign exceptions (scrap. surplus, and stock differences) at the plant or grouping WBS element level.

For more information, see Assigning Exceptions .

You have executed material requirements planning (MRP).

For more information, see Starting a Multi-Level Single-Item Planning Run .
