Backend Services are already registered for System Alias

Hi Team,

I tried to activate ODATA service (GRC_ACCESSREQUEST_TRACK) through transaction /n/iwfnd/maint_service but it shows an error 

"Backend Services are already registered for system Alias 'EQ1' "

1. GRC_ACCESSREQUEST_TRACK service is presenting in/n/iwfnd/maint_service transaction but not in ZGRC_ACCESSREQUEST_TRACK.

This service is presenting SICF also.

Note: Without conversion of ZGRC_ACCESSREQUEST_TRACK, we can't transport to Quality.

If i am wrong, Please help me.

Thanks

Raja
