User exits

[Former Member]

Pls. tell me where do we use user exits and why?

[Former Member]

few examples for why?

Following are the some of the user exits available for PS related functionalities.

CNEX0006 - to add Customer-specific fields in the project definition

CNEX0007 - to add Customer-specific fields in WBS elements

COZF0001 & COZF0002 - Change purchase requisition for external procured components (std. SAP allows only one PR document type in PS, where with help of these user exits u can use more than one PR document type)

Hope this helps.

Hi,

User exits allow you to add additional functions to the SAP standard.

Programs with user exits contain subroutine calls at certain points in their syntax that are identified by the prefix USEREXIT. The actual user exits are located in an include that has been assigned to a module pool. This is where customers can include any changes (enhancements) that they want to make to the system. These includes are always processed during program flow.

Advantage: In principle, customers can modify anything they want that is found in the include (tables, structures, and so forth).

Disadvantage: SAP cannot check the individual enhancements themselves which often leads to errors in the enhancement process.

Regards,

Amit
