Hi @henrikmonfort ,

Could you tell us more about the tables/content of the two GIs you want to join and the business requirement?

Thanks

Note: This solution proposed here could be useful for a developer.
In such cases, the developers can also use SQL Views to combine the tables, Create a  DAC for the SQL view (with proper CompanyID as a field in the SQL View, and by using IsKey =True defined on the key fields), and then create the Generic Inquiry. The newly created DAC will be available to create GI.

Hi @henrikmonfort,

Depending on the business requirements for the report, another option may be to use subreports.
