We had a billing document which calculates 50% discount. The amount of discount posted in FI was 12,000 SGD while the tax amount posted was 1,440 SGD. The correct discount amount should be 10,560 SGD. It seems that it doesn't calculate the discount with regards to tax amount. How can we come up with the net discount amount of 10,560 SGD? Are there any configurations available that can fulfill our requirements?
