Dear Pronojit/Mani,
Thank you so much for your guidance. Many Many thanks. I am learning SAP on IDES system on my own so dont have any FI consultant. I put this query on SCN on 19th Jun and find the solution on 23rd Jun. Although It took me 4 days to know that TAXINN is not a pricing procedure but Tax Procedure. In these 4 days i searched again and again on SCN and google and learned many things apart from this Tax procedure 
. Many thanks for your cooperation guys.
Regards...
