Hi,
If you are trying to implement new tax procedure in running production system, it is not recommended. You may make the required changes in existing tax procedure.
For service tax reversal mechanism (INDIA), you can make the necessary changes in existing tax procedure as explained in the note: 1736781 - Service tax Legal changes for Abatements and Negative list
The note explains the procedure to be followed and the new condition types to be created. Please check the mentioned note and follow the procedure.
Regards,
