Hello experts
It's first time to use the production floor execution interface , I need to add a new field with lookup in the active job form , after that the value in the new record will be inserted in the journal that will be created in the job card in the production ordrer
First i Created a new field in the data source , and create the lookup in a event handler class.
But the grid and the data source (edit = no) , I can chnage the grid but the can't do that whith the data source (maybe this is not the problem that made the lookup don't work )

How i can start this task
Thanks all
