mycleint has two departments one is production and another one is R&D department.
when we procure the matrials for production department the the tax should not be included in the material price but when we procure for r&d the tax should be included in the material valuation price.
also the material is transfered between these two departments quite oftenly so how to maintain the required tax process.
how to configure this in the system
please provide the solution.
