You have maintained a 12 character length GTIN number in the Material Master, but when you preview or print the Delivery Note, the system is adding a checksum at the end of the barcode.

Reproducing the Issue

  1. Navigate to the Product and Service Portfolio work center.
  2. Go to the Products view.
  3. Find and select the product ABC (ABC represents the Product ID).
  4. Click the Edit button and then on View All.
  5. Go to the General tab and then to the UoM Characteristics subtab.
  6. Under the GTIN column you can see that a 12 digit GTIN code is maintained.
  7. Now navigate to the Outbound Logistics work center.
  8. Go to the Outbound Deliveries view.
  9. Find and select the relevant Outbound Delivery XYZ (XYZ represents the Outbound Delivery ID).
  10. Click the Preview button to open the PDF document.
  11. You can see the barcode of the Product ABC is displayed with 13 character length on the Delivery Note. The system has added a check digit at the end to make the code 13 character.


You are using an 'EAN13' type of barcode in your Delivery Note form template. 'EAN13' barcodes always add a checksum digit at the end. This is the standard behavior of 'EAN13' barcodes.


For GTIN with 12, 13 and 14 digits, you can use a barcode type which does not add a check digit at the end of the barcode. In barcode type 'Code 128' for example, no checksum digit is added.
