I have one more question:
I’m sure someone can help me this time, too. How can I change the position of a column (field) in a table view?
Select the column header in the Direct Desk, then open the context menu with the right mouse button. There you can enter the new position under Sequence. As an alternative to the position you can also specify +x (move x places to the right) or -x (move x places to the left).
