Need Help on restricting selection box value

[#1]

Hi All ,

How to hide values in a  Drop down selection based on another column,

I mean I have a Multi box, where I have kept my selections, I need to hide Employee ID values based on the another selection when EMPL_Status = 'T'. How can I achieve this ? Any idea. Please help me on this !

May be an expression...

Aggr(Only({<EMPL_Status -= {'T'}>} [Employee ID]), [Employee ID])
