This module introduces the ability to define a quantity control point on Receipts and Vendor Bills by Work Acceptance. Only the products and services that have been included in a Work Acceptance can be received and/or invoiced.
auto_awesome What this module does
AI-generated from the code · Odoo 18.0Create Work Acceptance records to control what quantity and price of a purchase order can be received and billed. Receipts and vendor bills must match an accepted Work Acceptance before they can be validated.
This module adds a Work Acceptance document used as a quantity and price control point between a purchase order and its receipts and vendor bills.
Users create Work Acceptance records from the Purchase menu or directly from a purchase order with the "Create WA" button. Each record has a vendor, responsible person, due/received/accepted dates, an invoice reference, and lines with product, quantity, unit price and subtotal. Lines are pre-filled from the purchase order lines. The document moves through Draft, Accepted and Cancelled states using the Accept, Set to draft and Cancel buttons; accepting can ask for the accepted date.
On the purchase order you see a WA counter button, an "Accepted" quantity column and a "WA Accepted" flag, plus filters "WA Accepted" and "WA Not Accepted" in the search. On incoming receipts a WA Reference field appears and can auto-fill quantities; validation is blocked if the done quantity does not equal the accepted quantity. On vendor bills a WA Reference field appears and posting is blocked if billed quantities differ from accepted quantities. A wizard lets you pick which Work Acceptance to bill.
Settings under Purchase let you enable Work Acceptance on purchase orders, goods receipts and vendor bills, and enforce it on receipts and bills. Operation types can be flagged to bypass the requirement.
