9.2 Voucher Approval

Hi,

We are in the process of implementing voucher approval in 9.2 for non PO vouchers alone. For this we are considering the below condition

Voucher origin in the header should be ONL and PO_Id should be blank in voucher line.

Based on the above condition, when a voucher is created with origin as ONL and with out po_id, the approval is triggered properly.

How to mark all other vouchers ie vouchers submitted with origin other than ONL and with PO_ID as approved automatically ? in this case the when a voucher is submitted the approval work flow should not trigger and the voucher should be auto approved.
