Hello Prajaskta,
I have already given you detailed steps for activating GRC web services, Please follow the same.
Please check my earlier response.
Until you does that, you will keep on receiving same error.
Try first activating service: GRAC_LOOKUP_WS with the steps I given earlier and you will see that after running initial load you will get error for different webservice. You need to enable all GRAC* services.
