Vertex Canada - Canadian Purchase Tax accounting

Dear all,

I have an issue.

My customer uses JDE 9.1 and  Vertex for Taxes for AP and AR both in Canada and United States.

For Canada we want the system to imput a specific Account for tax on purchases.

The system performs the correct accounting entry in 3-way match but not in 2 way and standalone vouchers.

in these latter cases the system increases the amount of the expense instead of imput a separate account.

case 3 way match- If I do enter a Purchase order and I receive it, the system during the receipt books the Account I need (that I have set up in the dmaai 4350)
