F4 help for BEx variables
Could anyone help me in implementation the following scenario:
I have the BEx variable available for input. Then users press F4 to view possible values for this variable, I need to output the certan list of values (the list is defined by quite complex logic - user algorithm).
So, Do I have the possibility to catch the SAP processing of F4 help and program my logic for the output list (some kind of exit)?
Please suggest any decision or the source of information according this issue.
