# Advanced sub batch numbering

Life Sciences Supply Chain Management also allows defining a structure for the generation of sub-batch numbers. The sub-batch number structure is item-specific and defined in the **Sub batch number group** field in the **Released products** form (**Product information management > Products > Released products > Inventory Management** FastTab). If no rule is defined, the sub-batch numbers are by default generated as the batch number plus a sequential numbering (for example, BatchNum-###), defined in the **Default sub batch ID format** in the **General** tab of the **Inventory and warehouse management parameters** form (**Inventory management > Setup > Inventory and warehouse management parameters**).

The rules for the generation of the sub-batch numbers are defined in the **Sub batch number groups** form (**Inventory management > Setup > Dimensions > Sub batch number groups**). The **Sub batch number group** allows to:

- Define the sub-batch number structure by specifying the segments that are going to compose the sub-batch number in the **Segments** FastTab. The available segments are:

> [!NOTE]
> Note
> 
> The sub-batch numbers can now be created independently form the batch number by not including the **Batch number** segment.
  - **Item number**
  - **Batch number**
  - **Date**
  - **Number sequence code**
  - **Site**
- Specify the **Date format** (for example, YYYYMMDD, YYMM, YYWK) in case the **Date** field is included in the **Segments** FastTab of the sub-batch number groups.
- Choose to identify the sub batches via a configurable number sequence (for example, SB###Site), by enabling the **Number sequence No.** parameter and populating the **Number sequence code** field in the **General** FastTab, or via a sequential numbering defined in the **Format** field added at the end of the sub-batch number (for example, SubBatch-###), only available if the **Number sequence No.** parameter is disabled.
- Configure the automatic reset of the sub-batch number sequence based on a predefined frequency (that is, never, daily, weekly, monthly, or yearly) in the **Reset number sequence** field.
- Select the separator to be used between the segments composing the sub-batch number in the **Separator** field.
- Define the default quantity per sub batch automatically populated when generating sub batches in the **Per qty.** field.
- Define whether the default quantity per sub batch can be overridden or not upon material registration by enabling the **Per qty. block editing** parameter.

**Example**

The **Sub batch number group** for item “RM001” is configured as follows:

- **Per qty** set to “50”
- **Number sequence No.** set to **Yes**
- **Reset number sequence** set to **Never**
- **Number sequence code** set to “SB###”
- **Separator** set to **Hyphen**
- The segments of the sub batch number group are set as follows:
  - **Number sequence**
  - **Date,** with format set as “YYYYWK”
  - **Batch number**

Multiple batches of item “RM001” are received in site AA on different dates. Each batch includes “100g” quantity. The batch and sub-batch numbers will be generated as follows:

| Date | Week | Batch number | Sub batch numbers |
