Value check for authorization groups has not been activated.

What causes this issue?

The value check for the authorization group (for example in the master
data of the contract account) first takes place, if it has been
activated in the global settings. The activation of this check enables
the values that have already been used to be entered into in the
relevant tables, since they are checked from this point in times and the
corresponding input help (F4) can be offered.
If the value check is not activated for the authorization group, it is
still possible to enter all values without further checks in the field
authorization object.
