Hi,

Yes, it is possible to create one Vendor Bill for two or more different Purchase Orders (POs) in Odoo. This can be done by following these steps:

1. Create and confirm the purchase orders that you want to include in the vendor bill. Ensure that the purchase orders are for the same vendor.2. If your workflow requires receiving products before billing, go ahead and receive the products for the purchase orders.3. Select the purchase orders you want to include in the vendor bill with the same customer.4. Select create vendor bill inside the Action menu.5. click Validate to confirm the vendor bill.

For example, refer the following image:

Hope it helps

Thank you, when i try to Confirm the Bill i receive the following error.

The above server error caused the following client error:

at XMLHttpRequest.

I receive this , from what i understand the code say  1 PO – 1 VB.

What do you think?

When introducing the vendor bill, you can use the field "Auto-Complete" in order to get the lines from the purchase orders, as many times as you need.

Select each of the Purchase Orders in the Auto-Complete field, one after the other, until all of the lines from every Purchase Order you want to Bill are added.
