Diagnosis
A characteristic with the Entry required indicator was hidden,because, for example, a precondition is not fulfilled. This means thatno value can be assigned to the characteristic. However, theconfiguration process is not complete until all requiredcharacteristics have value assigned to them.

Procedure
If you want to save the configuration anyway, set the status of theconfiguration to locked or incomplete.
Before you can change the configuration status to released, youmust delete the Entry required indicator. You can then use aselection condition to define that the characteristic must have a valueassigned to it if a precondition is fulfilled.
