Pegging Logic
There are two reports available for running pegging:
● RPEGALL2, which is an advanced pegging report accessed from transaction PEG01N
RPEGALL, which is accessed from PEG01
For pegging report RPEGALL2 , you can create a run profile to define its behavior, including business-related settings, performance-related settings and log settings. To do this the following transactions are available: <DS:SIMG.PEGRP>Make Settings for Pegging Run Profile
Make settings for pegging run profile (transaction PEGRP )
Make settings for run profile messages (transaction PEGRPM )
Make settings for movement types (transaction 0PEG02 ). For more information, see Goods Movements that Affect Pegging and Distribution .
The following pegging logic types exist:
Not Fixed (always follow MRP logic)
Fixed (follow historical pegging assignments)
Combination (follow historical for purchase orders and production orders and MRP logic for purchase requisitions and planned orders)
