Rectification request

i filed a rectification request for tax credit mismatch as tds in form no.16 was not matching with 26AS.......but the request has been processed and status is "Rectification Processed No Demand No Refund"......

i thought the case would be referred to regional AO, but the rectification request got processed at CPC........can anyone tell me how to file another rectification request so that the case is referred to regional AO.....??
