Transfer of nri indian income after paying taxes

I AM AN NRI AND HAVE INCOME IN INDIA FROM PENSION, BANK INTEREST, HOUSE RENT. I HAVE PAID INCOME TAX FOR PREVIOUS YEARS SAY 2010 AND HAVE INCOME TAX  DEPT. ACKNOWLEDGEMENTS / ORDERS UNDER SECTION 143 FOR REFUND / PAYMENTS.

I WANT TO TRANSFER THIS MONEY [ ABOUT 10 LAKH] IN MY NRE ACCOUNT IN STATE BANK OF INDIA IN INR.

QUESTION:       IN FORM 15CA CAN I ENTER INCOMETAX DEPT. COMMUNICATIONS ABOUT TAX PAID INSTEAD OF  CA CERTIFICATE.  A.O.  OREDERS UNDER SECTION 195  & 197 ARE ACCEPTABLE.  INDEED SECTION 195 & 197 ARE ABOUT CURRENT INCOME FOR WHICH TAX IS TO BE PAID. IN MY CASE TAX HAS BEEN PAID AND INCOME TAX DEPARTMENT ACK. EXITS.

ARE THERE SEPERATE PROCEDURES FOR FOR INCOME FOR WHICH TAX HAS ALREADY BEEN PAID?

THANKS
