We are using vat codes with type of vat "on payments".
When a customer pays an invoice parcialy, the vat amount is for the total of the invoice and not for the paid amount.
Does anyone knows if there is a parameter for this.
Thanks

Although we're not familiar with this type of tax handling (where are you using this?), I'd suggest to test the cmg parameters:

tfcmg0100m000, Form3, Adjust Tax for Deductions (avat). This applies to payment differences, that may act the same as partial payments.

Have you checked with your local Baan support. This sounds like a bug. What Baan version are you running?

Thanks Maria, I found a solution at support site, it was a bug on standard
