I'm quite new to NAV and while trying to filter the OnLookup list I stumbled across some difficulties. I want to limit the number of possible choices, let's say workers, when unrolling the OnLookup list on page. I tried following the guide that seemed to help to achieve a similar result though it didn't quite work for me.
Could anyone point me in the right direction? I played with some built-in functions but a simple SETRANGE doesn't seem to do the trick.
