Hi Nitin,
1. Create 3 conditions as CC Rec.Debit with plus sign, CC Rec.Credit with minus sign & Service tax exp in OBQ1
2. Create 3 account keys for the same in OBCN with posting indicator as 2 and tax type as input tax
3. Assign the condition types along with account keys in the tax procedure in OBQ3
4. Maintain the GL accounts for the keys in OB40
5. Maintain the tax rates with signs for the tax code in FTXP or in the tax conditions in FV11
After done the above configuration, check the posting.
Regards,
Mukthar
