I am facing quite unusual error in GST calculation while raising purchase order. When I apply the tax template to purchase order the calculation of 9% on net total calculating wrong.
I found the problem, the reason behind miscalculation on GST is my PO involves transportation and packaging (Services)which falls under different 12% GST slab, and Raw material falls under 18% slab , since its PO print format is not customized on this hence it calculating 12% on 2 items rows
The solution: what i did is I raised two separate POs one for Transportation and Packaging and others for materials.
There is one more solution where we can put GST on actuals which is technically not right when there are services and materials involved
