Split and merge manufacturing orders¶
In Odoo Manufacturing, it is possible to create manufacturing orders for a single unit of an item, or multiple units of the same item. In some cases, it may be necessary to split a manufacturing order that contains multiple units into two or more orders, or to merge two or more orders into a single order.
Important
A manufacturing order can only contain one unit of a product, or multiple units of a single product that all use the same Bill of Materials (BoM). As a result, it is only possible to merge manufacturing orders when every order contains the same product being manufactured with the same BoM.

To split a manufacturing order into multiple orders, begin by navigating to New button, the manufacturing order’s reference number appears with a ⚙️ (settings) button next to it.

After clicking Split, the original manufacturing order is split into the number of orders that was specified in the Split # field. The reference numbers for the new manufacturing orders are the reference number for the original order with -### tags added to the end.
Example
Manufacturing order WH/MO/00012 is split into three separate orders. The reference numbers for the new orders are WH/MO/00012-001, WH/MO/00012-002, and WH/MO/00012-003.

The selected manufacturing orders are merged into a single order. The reference number for the new manufacturing order is the next sequential number that has not already been assigned to an order.
Example
The last reference number used for a manufacturing order was WH/MO/00012. Two manufacturing orders, WH/MO/00008 and WH/MO/00009, are merged into a single order. The reference number for the manufacturing order created by the merger is WH/MO/00013.
In the Source field for the manufacturing order created by the merger, the reference numbers of the manufacturing orders that were merged are listed.
Example
Manufacturing orders WH/MO/00009 and WH/MO/00010 are merged to create WH/MO/00011. The source field for WH/MO/00011 lists both WH/MO/00009 and WH/MO/00010.
