Steps to reproduce the bug:
- Let's consider product P with purchase_method = 'purchase'
- Create a purchase order PO and puchase 20 units of P to a vendor
- Confirm PO and create a vendor bill VB the 20 units of P
- Validate VB
- The invoiced quantity on PO is 20
- Go to the Purchase report and analyse the qty_to_be_billed
Bug:
The qty_to_be_billed was still equal to 20 instead of 0
