I created a user defined table with two user defined fields. I registered the table with a header line layout. I have a formatted search to fill the second user defined field based on the value of the first one. The formatted search is working right now as intended, and each time the value of the first field is changed, the value of the second one is automatically populated. But if I go back and update the registration of the table and made this time the second field a non-editable field in the form, the formatted search stop working.
What I need to do is: to fill automatically the second field based on the first one value, and to not allow the user to change then value of the second field.
Is there a way in which I can do this?
