GtinRequired(20030004, InvalidData)

Description

This error occurs when the product is missing a GTIN/EAN (Global Trade Item Number). The receiving system requires every product to have a valid GTIN in order to be processed correctly.

Cause

• The GTIN/EAN field is empty or completely missing.

• The GTIN is provided in the wrong field or at the wrong level (e.g., on the group instead of the variant).

• The field exists but is filtered out in the mapping.

Resolution

1. Provide a valid GTIN/EAN for the product/variant.

2. Ensure the GTIN consists of digits only and has the correct length:

   • GTIN-8 = 8 digits

   • GTIN-12 (UPC) = 12 digits

   • GTIN-13 (EAN) = 13 digits

   • GTIN-14 = 14 digits

3. Verify that the check digit (GS1) is correct.

4. If the product lacks a barcode: check whether the receiving system supports exceptions/a custom item code; otherwise a GTIN must be registered.

Example

• Valid: GTIN = "7312350333374" (13 digits)

• Valid: GTIN = "012345678905" (12 digits)

• Invalid: GTIN = "" (empty field)

• Invalid: GTIN = "B11E905" (contains letters)

• Invalid: GTIN = "12345" (wrong length)
