I created the Field AZBProductivityUnit in the table CustPackingSlipJour and inserted it in the form CustPackingSlipJournal. This field of type String needs to be populated with the address of the warehouse associated to that line, so I have to copy this value inside my AZBProductivityUnit. The address of the warehouse is in the form InventLocation stored in the Data Source LogisticsEntityPostalAddressView under the field Address. In addition to that, the field AZBProductivityUnit should be editable, but this modification doesn't have to change the field Address of the warehouse. Anyone has any tip for me ? I tried several coding solutions but no one seems to fit my problem. Thank you very much to anyone who will help.
