Thanks a lot, Jwala, for reply.
Still not sure if BP required. The note that you mentioned 1685257 explained it, please see the picture below. It's just upload from PFCG to PCD.
Regarding the HR Renewal. Is it optional or not? If we upgraded ECC 6.0 EHP7 does it mean that we should upgrade to HR Renewal or we can stay with old ESS/MSS? Is there any impact? What add-on we should have for ESS/MSS if not upgrade to HR Renewal 2?
Thanks again!
