Tax is calculated when validate with a concurrent request.

Hello everyone

I have a strange case that need your advice.

There are invoices that match to POs, invoices that are manually validated on Invoice Workbench do not have tax calculated.

However, invoice that are validated by the concurrent request, there is tax calculated.

Is there anyone experience this and could you please advise why is the result different?

'Allow Tax Applicability' option at supplier and supplier site are not checked.

Below is Tax defaulting order

Thank you.
