QR Scanner Works Fine, but how to delete Entry

Hi,

I have an Action, that Opens a Form with a Column Require, Scan and Autosave that Opens the Detail View.

All Works Fine, but how can i Clear this Entry before Scanning.

If the entry is not deleted, the autoscan function will not work the next time the scanner is started because there is already an entry in there

I think I have answered it myself …
Since Require is necessary for the autoscan … I cannot delete the entry.

I had already thought about a temporal variable, but it always ends with the same problem
