Issue with GST Calculation When Adding Freight Charges in Purchase Order

ERPNext
1

Hello everyone,

I am facing an issue with GST calculation in ERPNext. When I add freight charges in the Purchase Order, the total of items + freight charges equals the GST amount calculated. This seems incorrect.

I want GST to be calculated only on the item total and not on freight charges. How can I configure the Taxes and Charges settings correctly to fix this issue?
