Swachh bharat cess is getting calculated on wrong base amount in miro. For example freight amount is 100 in po and while posting miro for delivery cost (freight) in ref to po the swach bharat cess is getting calculated on a different amount but not 100. Where as it is suppose to get calculated on 100 only as the miro amount is 100. Not getting any clue from where it's taking the base amount for the same. Any input will be helpful.
