You can scan and parse GS1 barcodes for lot and license plate tracked items tracked items, and the system calculates the quantity based on the barcode data.

The system supports parsing barcodes scanned in multiple steps, including partial barcodes, for both lot-tracked and license plate items.

To scan GS1 barcodes in physical count, follow these steps:

  1. Open the Physical Count screen.
  2. Scan the GS1 barcode (item reference number, lot number, and quantity) for lot-tracked item.
    The system populates the mobile scan entry with the item number, lot number, and quantity. Additionally, the system works similarly when you scan the barcodes for license plate-tracked items.
    For accurate parsing, scan GS1 barcode elements in the following sequence:
    1. (00) License Plate Number
    2. (01) Item Reference Number
    3. (10) Lot Number
    4. (37)/(31)/(32)/(33)/(34) Quantity
      • You can also perform a partial scan by first scanning a barcode with Application Identifier (AI) (00) for license plate, then with (01)/(02) for item, and finally with (10) for lot or (37) for quantity, This is only supported when the license plate contains multiple lots or items.
      • If the license plate is associated with an item and a lot, you can scan a barcode with AI (00) for license plate and then 37 for quantity.
      • When barcode fields are split across multiple labels, the system prompts you to complete the required fields accordingly.

  • The system skips the GS1 barcode parsing logic when the Ignore Parsing toggle in the Mobile Warehouse app is turned on, even if the Value field is set to Yes for the Parsing by Default description on the Mobile Profile Setup page.
  • The scanned barcode is interpreted as a raw value, such as a direct item number or lot number, instead of being split by AI values.
  • This override ensures that you can control the scanning behavior dynamically based on the situation without being restricted by global setup.

Parse GS1 quantity in physical count

You can scan the GS1 barcodes containing quantity-related AIs, such as AI 37, AI 31, AI 33, AI 34 and AI 32.

The system evaluates and determines quantity based on the scanned barcode using the following criteria:

  • AI 37: If found, this is used as the quantity.
  • AI 31: If AI 37 is missing, the system checks for AI 31.
    • If the item base unit of measure is kilograms (KG), the system uses the quantity without conversion.
    • If the base unit of measure is pounds (LBS), the system converts the quantity.
    • If neither, AI 31 is ignored.
  • AI 32: If both AI 37 and AI 31 are missing, the system checks for AI 32.
    • If the item base unit of measure is pounds (LBS), the system uses the quantity without conversion.
    • If the base unit of measure is kilograms (KG), the system converts the quantity.
    • If the base unit of measure is different, the system ignores AI 32.

If none of the above AIs are present in the scanned barcode, the Quantity field value remains blank, and you must enter it manually on the Physical Count screen.

The system populates the Quantity Handled field value in the physical count based on the first valid AI encountered as per the configured AI sequence.
