Hi all,
I want to create an excel template just like Sales Header and Lines template that is found in sales table for export in my custom form through the open in excel button.
I have created custom entities for my tables and have created relations between them.
Now, when I add the fields for the header entity in excel through the addin, I cannot add the fields for the lines entity as the plus button is disabled and it is saying that no related tables are found.
