SAP Message RP787 - Conversion not performed for record with key & &

Diagnosis
While attempting to import the predefined cluster structure, the systemdetected an inconsistency between the numbers or names of the objectsto be imported and their definition in the HR import interface. Theimport was terminated because the standard conversion program was notable to convert the record.
Possible causes are a corrupt data format or new customer objects inthe relevant cluster.

Procedure
If you have not changed the cluster structure defined by SAPusing your own programs or transactions, please delete the record fromthe database before production startup. Most HR cluster recordscan be restored by HR application programs once the relevantrecalculations are performed. A database record of this type usuallyaffects only one personnel number. In critical situations, call theHotline.
You can use the utilities RPUPxD00 and RPUPxD10 to delete records fromHR cluster databases. The 'x' stands for the number of the PCLxdatabase (1, 2, 3 or 4). Records should only be deleted by anexperienced and authorized HR system administrator. If you have anyquestions, please call the HR Hotline.
If you have changed the cluster structure in previous releases usingyour own programs, contact your consultant. The conversion will need tobe reprogrammed for your special case.
