I have added default operator 'Is empty' to a custom field 'ZZFLD00002D' using path SPRO -> CRM Cross Application Components -> Generic Interaction Layer/Object Layer -> Component Specific Settings -> Define Operators for Dynamic Queries . But this operator is not working.
This operator is properly working for other custom fields .
I even tried to add this operator by redefining Get_dquery_definitions method of ..IMPL class but couldn't make it out.
Is there any solution for this issue?
