At present i am working on SAP 6.0 EHP6.

In SPRO there are option to determine the service tax catagory.

FI-MM

MM

• First of all i want to understand what is the use of maintaing the service tax catagory in above combination



• Secondly what is the difference between FI-MM and MM service catagory maintenance



• Thirdly what is the difference between FI-SD and SD service catagory maintenance



• Fourthly, can we determine service tax catagory in FI transaction like FB60, F-43, FB70



• During maintaing of FI-MM catagory, there is option to maintain service catagory with Taxcode, GL, Vendor combination. in this, which gl account do we need to maintain.



• At present the service tax payable is applicable in SD side also input purchase side ( service tax reverse chargne mechanism) so do we need to maintain one service tax liability for both the scenario

Please help in understanding, as we are in process of Finalisation of Business Blue Print.
