Contract Replication as of EhP2

Hi Experts,

ECRMREPL ISSUE.

For a BP, I'm doing product Change in CRM, no errors in ECRMREPL  IS-U side.

Now i'm cancelling the same product in CRM, at this time i'm getting the following errors in ECRMREPL.

Please find the screen shot.

Transfer of CRM transaction 5035035 item 0000000010 to IS-U unsuccessful

Transfer of CRM transaction 5035035 item 0000000010 to IS-U unsuccessful

Contract changes from CRM noted for contract items 1000465011

I have gone through the following thread,

https://scn.sap.com/thread/2031760

In above thread mentioned FM should be ISU_CRMQ_CONTRACT_RESTART_52  if we get "Contract Replication as of EhP2 " as error.

In my case it was correct.

Please suggest where i have to check to in order to resolve these type of errors and in what cases these type of issues will come.

Thanks In advance.
