fms query does not work with tab button

Hi experts,

We have made an fms that returns an array.

When we press Shift+F2, we can see the results but when we press Tab button or the magnificent glasses, the fms does not working.

We don’t want to refresh it based on other field, because the user must choose values from the array.

Have anyone faced the same issue?

We are using SAP B1 9.0 PL04

Any advice would be appreciated.

Kind Regards
