Tax line created in invoice lines tab of Invoice WB for self assessment tax

Hi All,

I have set up self assessment tax set up for supplier invoices as per below Oracle notes

How to Configure a Tax to Self-Assess in R12 E-Business Tax (EBTax) Payables (Doc ID 948414.1).

When i try to manually enter invoice for the supplier, tax line is not getting generated at invoice lines tab and self assessment is calculating correctly.

But when i try to create an invoice manually in payable Open interface form, and import invoice into invoice WB, i have observed that tax line is getting created with Zero amt but self assessment tax is getting calculated correctly in this case.
