Purchase Requisition Grouped by Procurement

When Odoo needs to replenish stock, it can generate purchase requisitions automatically. Without this module, each replenishment run can create a separate draft requisition, even when the lines belong to the same procurement group.

With this module, the automatic replenishment process is flagged so that the system first looks for an existing draft purchase requisition that already belongs to the same procurement group. If one is found, the new lines are added to that requisition instead of creating another record. If none is found, a new requisition is created as usual.

• Only draft requisitions are reused; requisitions that are already confirmed or in another state are not touched.
• The grouping key is the procurement group, so lines from the same group end up together.
• This behaviour applies to requisitions generated automatically from stock rules, not to requisitions created manually by users.

The module extends the purchase.requisition model and the stock.rule model. It does not add new menus, screens, buttons or reports; the change is visible in the list of purchase requisitions, where fewer draft records appear and lines are consolidated.
