Enhancement for Purchase Requisitions with External Procurement

The following SAP enhancement is available for processing purchase requistions for material components

This enhancement helps you process data in your part of the program and transfer the data back to the standard system. You cannot change the externally procurred components themselves. Therefore every time you make changes to the component that affect the purchase requisition, you must execute this enhancement.

The enhancement COZF0002 contains the following enhancement components:

Function exits:

The component fields (table RESBD) and the fields from the order or network header(table CAUFVD) are available in the function exit. The modifiable fields are defined in the structure EBAN_ORD_CUST.

Activities

1. Create the enhancement.
Either create a new project or use an existing project.
2. Edit the enhancement component
Append the program coding for the function exit EXIT_SAPLCOZF_002. This transfers data from the SAP standard program to your part of the program and returns it later to the standard program. If certain fields in the structure are already filled during Import, carefully check what effects changes to a field have (in doubt do not change the original SAP content contents).
Call up the function module and double-click on the Include line. Create Include modules. If you define internal work structures, you should do so using the ABAP key word LIKE so that future SAP structure enhancements do not cause changes in your coding.
3. Activate the project.
Only when you activate the project does your enhancement come into effect.

Further Notes

Unlike modifications, enhancements are not influenced by a release update, since thea are not part of the original SAP system, rather they exist in an area reserved for customers.

The general procedure for creating enhancements is in the enhancement transction in the menu Tools -> Online manual.
