Best solution for search help for selection field VBPA-PERNR

Hi All!

I had created a SQ01 report and I have a selection screen field that reference field PERNR from table VBPA. My problem is that this field has no assignment to a search help or matchcode object (PREM) and I want to do this (offer to the end-user the possibility to select the PERNR value based on other fields).

From what I read, I can assign one search help to the field modifying the table VBPA. I don't now exactly how to do that and if this one is the best solution.

Any opinion from you is more than helpful.

Regards,

Florina
