Use

Application components: MM-PUR-PO, MM-PUR-PO-GUI

Main program: SAPLMEPO

The Business Add-In (BAdI) ME_PROCESS_PO_CUST enables you to extend the business logic of the Enjoy purchase order on an individual basis.

You can thus influence the dialog transactions ME21N, ME22N, ME23N, and ME29N, and the BAPIs BAPI_PO_CREATE1 and BAPI_PO_CHANGE.

Typical applications for this BAdI include:

• Processing of own objects

• Processing of additional data on standard objects

• Implementation of additional checks and derivations

• Change of data in standard fields
  Note
  Ensure that data integrity is guaranteed.

• Change in field selection

With its methods, the BAdI covers the complete transaction cycle for purchase orders. You can thus intervene with your own implementation in each step of the processing:
