Deletion flag not allowed with update type I (Matchcode ID &)

What causes this issue?

If the deletion flag is set for a matchcode ID, matchcode records are
not deleted physically. They are simply marked with a deletion flag.
However, when using update type I, matchcode data is implemented
directly as a database view. The SAP system does not save its own
matchcode records for this type of matchcode. Setting the deletion flag
therefore makes no sense for matchcode IDs of update type I.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Cancel the deletion flag.
