Search help behavior with user exit

Question

When a search help is executed you get a result (that appears in the internal table record_tab that satisfies your selection criteria. If, without leaving the search help, you enter a new selection it can return an entirely different set of records. That is the normal behavior and what users expect.
However, I do some processing in the CALLCONTROL-STEP = 'DISP' that pares down the result set in record_tab based on the users authorization. When I return to another selection it operates on the pared down result set in record_tab and does not make another selection. i.e. record_tab is not refereshed for the new selection. I am clearly doing something wrong.
This is the specific case:  Users are limited to customers in their specific sales group defined in KNVV-VKGRP. I use an exit in search help DEBIS to check whether the user is authorized for the sales group. A user is authorized for users in group 001 and 042. There first selection is from sales group 001. It returns 50 records. They decide that they chose the wrong group so they select sales group 042. It returns 0 records. However, had they selected from group 042 from the outset they would have had two hits. The second pass is working on the selection set from the first pass. (or so it seems)
Any thoughts?
