To allow users the option of enhancing and customizing the standard R/3 System, SAP offers two customer exits.

You can maintain these exits with the CMOD transaction:

Tools -> ABAP Workbench
Utilities -> Enhancements -> Project management

For information on the transaction, see the online documentation.

The function modules are combined in SAP enhancement COOMKPLV and have the following functions:

Function Module Exit For Include Programm

EXIT_SAPMGPLV_010 Costs LXPLVF01

EXIT_SAPMGPLV_020 Qtys/Prices LXPLVF02

Each exit is called up singly or mutiply for each planning transaction (RKP1, RKP2, etc.). In the exit, you can change, insert, or delete plan records in the transfer structure. For more information on the use of the customer exit and a description of the interfaces, see the documentation for the corresponding function module.

• EXIT_SAPMGPLV_010: Customer Exit for Costs Prior to Callup of Planning Data Interface
