🔧 Zalando - Error : PSERR_148: Two or more article variants belonging to the same article ID are mapped with the same colour codes combination.

Error message

PSERR_148: Two or more article variants belonging to the same article ID are mapped with the same colour codes combination.

What does this error mean?

On Zalando, two or more variants belonging to the same product model have been submitted with the exact same colour combination. Each variant within the same model group must either have a distinct colour combination or share the same "merchant_product_config_id" if they only differ by size.

How to solve this error

1. Step 1: In your Attributes Mapping, check the colour attributes ("color_code.primary", "color_code.secondary", "color_code.tertiary") and ensure each colorway has a unique combination.
2. Step 2: If variants share the exact same colour combination but represent different sizes, assign them the same "merchant_product_config_id" and differentiate them via "size_codes.size".
3. Step 3: Ensure model-level fields (such as product name, "season_code", and media like "media.media_path_01") remain strictly consistent across variants of the same model.
4. Step 4: Launch a manual product push in Lengow to update your data on Zalando.
