A few things to look:
a)In txn SE16, siaplay table HRP1050 with the object type ‘S’, your position id and infotype = 1050. If it has the details you had entered when creating the job eval results, then the problem would be display only. Else the insert or create is the issue.
b)In SAP Support website – SAP Service Marketplace
Go to SAP Support Portal, look for OSS notes addressing the problem. If there is any, then download the note and apply – can be done with txn SNOTE.
If not, continue to create an OSS message to report the problem to SAP. You need to give details of the problem along with the specific example of your case. SAP may need to access your system to analyse your problem and give necessary correction instructions.
If you are not yet familar with SAP Support portal, you need to know that asap.
Hope this helps.
