It is not when creating or editing the row. The row is created by another appsheet app 1. When creating the row, 5 fields are editable. 2. States are then fulfilled, which are determined by a change timestamp defined by the change in a column. And according to the state some fields become uneditable and others that were not editable or visible become visible.
The row is created when you load a sale. The creation date is saved there. When the delivery is made, data is entered, which means that the delivery date is saved. From then on, these fields (and the previous ones) are no longer editable and fields corresponding to the guarantee and return of the product become visible and editable. The problem is that these changes must occur after saving the form, that is to say in the next edition, and they happen while the form is being edited. By changing the field that triggers the change timestamp, the date is immediately displayed and the delivery fields are no longer editable, while more data is being completed. The idea is to complete all the data and after saving, if it is edited again, it is not editable and if the others are. I do not know if I knew how to explain.
