Error during Scheduling Parameter Customizing - Message SV033

Question

Dear all,
I am facing a problem when I try to assign a scheduling parameter to a service order in customizing with Tcode OPU7. I basically try to link my service order to the plant with a forwarding scheduling parameter and the system gives me the following message:
Specify the key within the work area
Message no. SV033
Diagnosis
You have attempted to create an entry whose key is not in the range defined for this area.
System Response
The entry cannot be created.
Procedure
Please check your entry.
There are several threads about that message in the forum here but it doesn't helped me to solve the problem.
Thank you very much for your help.
Bernd.

Answer 1

Dear Maddy,
The function "Reschedule" follows an all-or-nothing logic, which means that either all selected activities on a resource can be re-scheduled or the function (better the liveCache) cancels and no activities will be re-scheduled.
One reason might be that you have a pegging relation to a fixed activity (this might be a sales order, forecast, an activity outside the propagation range...) which cannot be considered during the
scheduling. The liveCache cannot break the pegging, therefore it cancels the scheduling.
Please have a look at the note 510669 which offers a heuristic on the basis of the algorithm /SAPAPO/HEUR_PLAN_SEQ_PACKAGES. This heuristic should solve your problem. It will re-schedule as many activities as possible and will not cancel if one fails.
Depending on your current release there could be also some correction notes like
1272960
1027194
I hope I could help you further.
Regards,
Tibor
