Hi,
You need to o following steps :
1. Create a tax code in FTXP with tax type as Output type.
2. Assign the tax code to company code.
IMG --> Logistics - General --> Tax on Goods Movements --> India --> Basic Settings --> Determination of Excise Duty --> Assign Tax Code to Company Codes
3. Assign the tax code for all transactions in OBZT.
4. Create G/L FS00
5. Assign tax code to G/L in OB40 for the appropriate key.
6. Create a condition record IN VK11.
