OSA - Status change not allowed

Hi,

we just upgraded to EhP4 and now are in the process of implementing the appraisal proces (Objective Setting and Appraisal).

After the final appraisal has been set to 'Completed' by the manager, we want the employee to be given the following options:

- Close approve - status set to 'Closed Approved'

- Close reject - status set to 'Closed Rejected'

- Reject - status set to 'In process' (for some minor, final textual changes requested by the EE).

The issue is that although the button 'Reject' supports a status change from 'Completed' to 'In process' (within standard SAP!!), SAP gives an error that a 'status change for 'Completed' to 'In process' is not allowed'

If I look into further help documentation regarding this error SAP gives a list of all possible status changes and here it clearly indicates that a status change from 'Completed' into 'In process' is allowed for documents using final appraisal.

Has anyone come across this error before and/or aware of possible solutions?

Thanks,

Wilfred.

PS: I searched OSS but couldn't find any relevant notes. If a relevant notes exists (which I was not able to find) any guidance toward relevant notes is also highly appreciated.
