--- title: "Serial and Batch Bundle" space: "ERPNext" url: "https://docs.frappe.io/erpnext/serial-and-batch-bundle" updated: "2026-02-26" --- > NOTE: Users must create a separate **Serial and Batch Bundle** for each stock transaction. They cannot use the same **Serial and Batch Bundle** across multiple stock transactions. > > *Allow Negative Stock* has been removed for Serial / Batch Items from version 15. From version 15 onward, users cannot make negative stock transactions for serial / batch items, even if *Allow Negative Stock* is enabled in **Stock Settings**. --- In version 15, we introduced the **Serial and Batch Bundle**. This feature is used to link Serial / Batch Nos in stock transactions. Before version 15, the *Serial No* field was a Small Text field, which meant one column could hold more than one serial number. Because of this design, there were a lot of data integrity issues. To solve this, we changed the *Serial No* field from Small Text to a Link field in version 15. Since we can't add a child table inside a child table, we added a new DocType: **Serial and Batch Bundle** to pick/dispatch multiple Serial / Batch numbers. ![Serial no Configure](/files/serial-and-batch-bundle.png) ## How does this work? You need to create a **Serial and Batch Bundle** and link it to stock transactions whenever you deal with Serial / Batch numbers. Users must create a separate **Serial and Batch Bundle** for each transaction, and they can't link the same **Serial and Batch Bundle** to multiple transactions. ### Auto Creation of Serial and Batch Bundle for Inward Entry If the user wants to auto-create a **Serial and Batch Bundle** for an inward entry, they must ensure that *Serial Number Series* is set for the serial item and that the *Automatically Create New Batch* checkbox is enabled (with *Batch Number Series* set) for the batch item. #### For Serial No ![Serial no Configure](/files/auto-serial-creation.png) #### For Batch No ![Batch no Configure](/files/auto-batch-creation.png) After the configuration, when the user creates a **Purchase Receipt** or a **Stock Entry** with the Type "Material Receipt", the system will automatically create the inward **Serial and Batch Bundle** on submission of the record. ![Auto Serial Batch Bundle Inward](/files/auto-create-serial-batch-for-inward.gif) ### Auto Creation of Serial and Batch Bundle for Outward Entry If the user wants to auto-create a **Serial and Batch Bundle** for an outward entry, they must enable the checkbox *Auto Create Serial and Batch Bundle For Outward* in **Stock Settings**. They can also set *Pick Serial / Batch Based On* to "FIFO / LIFO / Expiry" in **Stock Settings**. ![Auto Serial Batch Bundle Outward Configure](/files/auto-outward-configuration.png) After the configuration, when the user creates a **Delivery Note** or a **Stock Entry** with the Type "Material Issue", the system will automatically create the outward **Serial and Batch Bundle** on submission of the record. ![Auto Serial Batch Bundle Outward](/files/auto-create-serial-batch-for-outward.gif) ### Manual Creation of Serial and Batch Bundle for Inward Entry For the **Serial and Batch Bundle**, both **Serial No** and **Batch** records must already exist in the system. With the manual option, the user must first create the **Serial No** / **Batch** records in the system. Users can use the CSV import option to create **Serial No** / **Batch** records. The blank CSV template can be downloaded using the Serial and Batch Selector. ![create-using-csv](/files/create-using-csv.png) Complete GIF for manual creation of a **Serial and Batch Bundle** for an inward entry is as follows: ![manually-create-serial-no-inward](/files/manually-create-serial-no-inward.gif) ### Manual Creation of Serial and Batch Bundle for Outward Entry Using the Serial and Batch Selector, the user can pick the Serial / Batch Nos based on the "FIFO / LIFO / Expiry" method. ![serial-batch-selector-outward](/files/serial-batch-selector-outward.png) Complete GIF for manual creation of a **Serial and Batch Bundle** for an outward entry is as follows: ![manually-create-serial-no-outward](/files/manually-create-serial-no-outtward.gif) ### Serial and Batch Bundle Creation Using CSV for Outward Entry Now users can create serial and batch bundles for outward entries by importing a CSV file. ![](/files/Screenshot 2026-01-20 at 12.19.18 PM.png) ## History of Serial Numbers To check the history of serial numbers, see the report "Serial No Ledger". ![](/files/Screenshot 2026-01-20 at 1.15.35 PM.png) ## Serial / Batch Selector This is used to select Serial Nos / Batches manually. This popup is also used to create serial nos / batches automatically if they do not exist. ![serial-batch-selector](/files/serial-batch-selector.gif) ## Disable Serial / Batch Selector If users don't want to use the Serial and Batch Selector (popup), they can disable it through **Stock Settings**. To disable it, go to **Stock Settings** > Serial and Batch Item (TAB) > enable *Disable Serial No And Batch Selector*, then save. ![disable-serial-batch-selector](/files/disable-serial-batch-selector.png) ## Old Serial / Batch Fields Many customers requested that we retain the old serial and batch fields to address UX issues. In response to this demand, we retained the old serial/batch fields. These fields are solely used for entering serial numbers and batches. The system will automatically create the **Serial and Batch Bundle** upon submission of the stock transaction. To enable this feature, users must navigate to **Stock Settings** and enable the *Use Serial / Batch Fields* option (see the image below). ![use-serial-batch-fields-global](/files/use-serial-batch-fields-global.png) After that, when the user creates a stock transaction (for example, a **Delivery Note**), the system will show the old Serial / Batch fields. For more details, see the GIF below. ![user-old-serial-batch-fieldsd](/files/user-old-serial-batch-fieldsd.gif) Users can disable the old serial / batch fields at the transaction level too. ![use-serial-batch-for-dn](/files/use-serial-batch-for-dn.gif) ## Update Serial / Batch on Creation of Auto Bundle If the user wants to automatically update the Serial No / Batch in the Serial / Batch fields when a **Serial and Batch Bundle** is created, go to **Stock Settings** and disable *Do Not Update Serial / Batch on Creation of Auto Bundle*. ![update-Serial-Batch-on-creation-of-auto-bundle](/files/update-Serial-Batch-on-creation-of-auto-bundle.png) Case: 1. User has enabled *Use Serial / Batch Fields* in **Stock Settings** 2. User wants to create the **Serial and Batch Bundle** per single batch 3. User has set the auto-create batch in the **Item** master. 4. On submission of the **Purchase Receipt**, the system has created the auto **Batch** and **Serial and Batch Bundle**, and set the *Batch* and *Serial and Batch Bundle* fields on the **Purchase Receipt** line item. 5. Updating the value of the batch takes time. If you want to skip this step, enable *Do Not Update Serial / Batch on Creation of Auto Bundle* in **Stock Settings**. 6. With this, the batch column remains blank, but the **Serial and Batch Bundle** will have the value of the auto-created bundle. ## How to Use **Serial and Batch Bundle** [https://www.youtube.com/watch?v=-VjZvRtdjDQ&t=820s](https://www.youtube.com/watch?v=-VjZvRtdjDQ&t=820s)
