Diagnosis
Production order <(>&<)>V2& is part of a collective order which has the
leading order <(>&<)>V1&. For leading order <(>&<)>V1
there are
procurement element change records from Order Change Management for
Production Orders with the reason for change "Change to sales order".
Order <(>&<)>V2& may be affected by this change.

System Response
The system does not permit a deletion flag to be set/technical
completion/close for an order if procurement element change records
with the change reason "Sales order change" are still open for the
leading order.

Procedure
Carry out the change process for the leading production order
<(>&<)>V1& or cancel the change process by manually closing the
procurement element change records. Then carry out the function
"Set deletion flag"/"Technical completion"/
"Close" again.
