Production Grouped By Product

When Odoo needs to manufacture a product for a sales order (make-to-order), it normally creates a separate manufacturing order each time. This module changes that: before creating a new order, Odoo looks for an existing order for the same product, operation type, bill of materials and company that is still in draft or confirmed state, and whose deadline falls inside the configured time window. If one is found, the new quantity is added to that order instead of creating a new one, and the origin references are combined.

Grouping rules are set on each operation type (for example Manufacturing) in a new section of the operation type form: - MO grouping max. hour (UTC): the cut-off hour (0-23) used to define the grouping period; default 19. - MO grouping interval (days): how many days back the period covers; default 1.

Odoo validates these values: the hour must be between 0 and 23 and the interval must be positive. The module also avoids creating duplicate work orders and finished-product moves for orders that are being merged, and skips creating raw material moves when the target order already has them. It touches the manufacturing order, stock move, stock rule and operation type models.
