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.

## Split manufacturing orders

To split a manufacturing order into multiple orders, begin by navigating to **Manufacturing -> Operations -> Manufacturing Orders**, then select a manufacturing order. At the top of the page, next to the **New** button, the manufacturing order's reference number appears with a **⚙️ (settings)** button next to it.

Click the **⚙️ (settings)** button to open the general settings for the manufacturing order, then select **Split**.

After selecting **Split**, a **Split production** pop-up window appears. In the **Split #** field, enter the number of manufacturing orders that the original order should be split into, then click outside of the field. A table appears below, with a line for each new manufacturing order that will be created by the split. In the **Quantity To Produce** column, enter the number of units that will be assigned to each new manufacturing order. Finally, click **Split** to split the manufacturing order.

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*.

## Merge manufacturing orders

To merge two or more manufacturing orders into a single order, begin by navigating to **Manufacturing -> Operations -> Manufacturing Orders**. Select the manufacturing orders that will be merged by activating the checkbox to the left of the name of each order.

![Select manufacturing orders that will be merged by clicking the checkbox for each.](https://docs.kmee.com.br/odoo/referencias/img/applications/inventory_and_mrp/manufacturing/management/split_merge/select-orders.png)

Once all manufacturing orders have been selected, click the **Actions** button at the top of the page, then select **Merge** from the drop-down menu.

![The Actions and Merge buttons on the Manufacturing Orders page.](https://docs.kmee.com.br/odoo/referencias/img/applications/inventory_and_mrp/manufacturing/management/split_merge/actions-merge.png)

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*.
