Hi
You need to create separate tax codes for service tax and excise. So you will have to maintain condition records in the tax codes for the respective condition types.So for eg, if the tax code for service tax is S1, than you will maintain the condition record in FV11 for the service tax condition type and if the excise tax code is E1, you will maintain the condition record for the relevant condition type against the tax code E1
This way you can have the multiple condition types including service tax and excise in the same tax procedure.
Thanks & Regards
