Problem in Service Tax

Hi,,

In ECC 6 version at present I am using TAXINN. While I am creating tax code (AB) for service tax 12.3% (12% Service tax + 2% Ecess + 1% HEcess), put value manually in FTXP and save the screen. After saving the screen if I want to see the record in tax code AB then value become disappear. No value is being saved under Tcode FTXP.

Thanks & Regards,

Mr. Roy
