Diagnosis

This authorization field is used in authorization objects for which authorizations exist.

Making a change in the authorization field with regard to the assigned data element could lead to inconsistent authorizations.

System Response

In this case, it is only possible to make restricted changes to the authorization field.

Procedure

Use the where-used function in transaction SU21 for the authorization objects that use this field, to determine the users (authorizations) and remove them.
Once there are no longer any authorizations for the authorization field, you can make a complete change.

Caution: Consider the consequences for authorization checks implemented in ABAP before continuing the process.
