ESS/MSS BP upgrade ????
We had 4.7 R/3 as Backend, ESS/MSS Business package 50.4 , EP 6.0
We are upgrading the 4.7 R/3 to ECC 6.0 , EP 6.0 to EP 7.0. But we are not planning to upgrade ESS/MSS BP.
1) Please suggest if we can manage with the existing BP or we really need to upgrade it also.
2) "Create Leave Request" & " Leave request Overview" are ITS based screens which when migrated from Stanalone ITS to Integrated ITS are not working.
Is upgrading the BP the only solution? If yes which is the compatible BP to be upgraded.
I have checked SAP Note1004528, 871026.
