Release 3.0D contains a user exit which enables you to create new text variables for use in applicant correspondence (see release notes for 3.0D). With release 3.0E this interface has been enhanced so that you can decide for each variable whether or not it must contain an entry in the text. The system calls the routine check_customer_exception in report ZPAP3CUS for each text variable which contains no entry. You can then set the individual fields to optional by their names.
Example
The system contains a module pool called MPAP3CUS for use as a copy template for your module pool ZPAP3CUS. The structure T500P is entered in this module pool. The system reads the personnel area to which the applicant is assigned in this table. For this reason, infotype 0001, Organizational Assignment , is declared as tables P0001 in this module pool. These routines therefore provide you with the addresses of the personnel areas. The PO box for the personnel area is set to optional in the routine check_customer_exception.
