Activate Enhancement pack 4 and business function OPS_PS_CI_1

Hello Experts,

We are in ECC 6.0 component version. I need to activate business function OPS_PS_CI_1 and for this I must activate EhP 4 in the system.

First I want to know whether it is compatible with ECC 6.0 as we have not activated any EhP so far.

If yes, then can you please tell me how to activate the same in the system along with the business function.

NOTE: I am not having Basis person now in place to activate it, so I want to activate it in sandbox to test the functionality of business function.

Seeking your guideline on the same.

Thanks & Regards

Saurabh
