Anyone able to get this working? I tried what Neeraja P suggested in sugarcrm filter on relative field - Dev Answers & Best Practices - DevClub - SugarClub so far not working. Here is the code I am adding to custom/Extension/modules/RTPOL_OLP/Ext/Vardefs/sugarfield_contacts_rtpol_olp_1contacts_ida.php
$dictionary['RTPOL_OLP']['fields']['contacts_rtpol_olp_1contacts_ida']['filter_definition'] = [ [ 'account_id' => '#accounts_rtpol_olp_1accounts_ida' ] ];
I am trying to filter Contacts based on Account, but getting this working will lead to other filters.
