Input and Out VAT account as Control Account

Hi Guys,

Please assist with the following:

We would like to set both the Input and output VAT accounts as Control Account so no manual entry can be created by mistake to these VAT accounts. However we faced the following:

1. After setting both Input and Output VAT account as Control Accounts we will not see these account on the List of Accounts window anymore. This is correct and exactly we will need. But we also cannot see these account when we try to setup the Tax Codes.

So my questions is after setting the VAT accounts as Control Account how do we setup Tax codes so VAT on AR and AP can be automatically booked to the correct VAT control account?

We are using 2007 A PL 38.

BR,

Jimmy
