Thanks Siddharth,
I followed the suggested steps but cannot activate the HCM_ESS_WDA_1. It says the
"It is not possible to activate business function CA_CATS_CPR"
When I checked the CA_CATS_CPR which is already activated it is giving the same message, and message detail says to activate the CA_CATS_CPR_CORE.
When I am RE-Activating the CA_CATS_CPR_CORE the same message again pops-up.
Kindly suggest.
