We thought you might like to know how to avoid an empty row in the reports.
As an example I have here an Asset handover protocol for vehicles and office equipment. if I don’t have any office equipment assigned to an employee, I don’t want an empty row in the report.
Select the DataBand you want to set up, select Properties => Behavior => Enabled => Edit expression => and use a code of this type:
Transmission_processes_Equipment_Title_list.value != null && Transmission_processes_Equipment_Title_list.value != “”
Set the same for the vehicle and it’s done!
We hope you find this advice useful 
Thank you and have a beautiful day.
With kind regards,
