Enhancement for
Purchase Requisitions with External Procurement
The following SAP enhancement is available for
processing purchase requistions for material components
- COZF0001 Change purchase requisition for
external procurred 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:
- EXIT_SAPLCOZF_002 Data transfer purchase
requisition
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.
