Vouchers are created correctly while positing the approval journal line but Tax reversal line shows incorrect posting type. System is showing Sales tax instead of India GST. 

1)Please make sure Invoice register and invoice approval journal name are created.

1)Create invoice register journal from Accounts payable>invoices>Invoice register.

2) Create invoice register journal from Accounts payable>invoices>Invoice approval

Actual result:

Posting type showing as sales tax for India GST reversal in invoice approval journal.

Expected result:

Posting type for GST reversal should be displayed as India GST.
