Diagnosis
You have tried to change a field that cannot be changed by a user.There are several possible reasons for this:

• It is a field defined by the system (for example, a client)


• It is a field determined by the system (for example, shipment number,
overall status, settlement or calculation status)

• The field contains administrative data determined by the system (for
example, date, time, user for creating/changing)
