Issue with GST Tax Template Auto-Selection in Purchase Invoice Based on Supplier in ERPNext v15

Issue with GST Tax Template Auto-Selection in Purchase Invoice Based on Supplier in ERPNext v15

I am facing an issue in ERPNext v15 while creating a Purchase Invoice with India GST compliance enabled. The setup involves:

  • Two suppliers (Supplier A and Supplier B)

  • One item “Oil” which is taxable and has an assigned 5% GST Item Tax Template

Problem:

  • When I select Supplier A and add the “Oil” item in the Purchase Invoice, the GST is NOT calculated automatically.

  • On the item line in the invoice, the “Item Tax Template” field remains empty (not auto-selected) and the “GST Treatment” is blank.

  • When I select Supplier B and add the same “Oil” item, the system automatically picks the 5% Item Tax Template and sets the “GST Treatment” to “Taxable”.

I have cross checked it multiple times and the suppliers are the same in every aspect and there is no inconsistency for the same.

Please help.

Hello,

Is the tax category set in Supplier or Invoice?

The Item Tax Template is filtered on the basis of the tax category.
