We have transfered the accumlated credit (which we received credit on our erection commissioning activity done at our client place by our nominated vendor) from our HO to manufacturing unit through ISD. Central Excise people objected to avail the such credit at our manufacturing unit due to credit received through erection commissioning activity which is post manufacturing activity.
Hence, we reveresed the same in our factory books (RG23 Part II) and taken credit in our HO Books. Now Service tax people are objecting to take credit in HO.
Kindly suggest any body - how to proceed further.
