CATS and WBS

Hi All,

We are implementing CATS Classic without ESS and the times would come from the Time Recording system as raw data.Its an SAP certified system and so there is a standard interface from it to CATS.

We want to transfer the data from CATS to HR/PS.For PS I think there is a way to default the WBS using a User-Exit.It would be great if anyone can throw some light as to how the WBS can be deafuted in CATS Data entry profile. And would also like to know about the importance of worklist.

Thanks and Regards
