Diagnosis
A signature network that uses a signature strategy to set the status"Change Possible" for the object management record is assigned to theselected change type. The system implicitly sets this status whencreating an object management record for a change order.
To avoid any breaches of security, the system only permits a digitalsignature to be executed in the maintenance transactions of EngineeringChange Management and therefore excludes the use of the selected changetype here.

System Response
It is not possible to use the selected change type.

Procedure
Assign a suitable change type to the object.
