custom tab special select

Hi @sevo, solution would be to:

• use search functionality (Search in Context) with object relations - in your case would be sales person equal to  representative ID (search variable pointing to parent object through use of i_hWndParent)
• save your search
• and then in RMB Properties set Startup Query to your saved search

I’m not sure how it would work for your custom tab, however you can test it yourself based on Sales Quotation tab and comparing Representative ID from header to Coordinator on line

SQL search expression in Advanced search: upper( AUTHORIZE_CODE ) = :i_hWndParent.frmBusinessRepresentative.dfsRepresentativeId 

Hope it helps :)

Best regards,
