Vijay,
I have the same problem and I am a bit confused by your instructions. I am trying to create KAs but I'm unsure how to Activate the Enterprise Search business package and the ESH Cockpit service,
Define the RFC link to TREX, Create the Search Object Connectors, Index the Search Object Connectors, and Schedule regular indexing of the Search Object Connectors. Can you please elaborate on how to do those? Thanks!
