Issue with GST Calculation When Adding Freight Charges in Purchase Order

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?

and When i save this that time getting this error

Any help would be appreciated.

change type to actual , not the previous row.


When change type to actual and trying to save that time showing this error
