Warning

CII-SR-048: Remove the separate manufacturer product number

In short

Warning: worth checking.

CII-SR-048 warns that a CII invoice line contains ram:ManufacturerAssignedID. Remove this separate manufacturer number. If you need to retain it, put it in the item description (BT-154), or use the seller's item number (BT-155) if it genuinely serves that purpose.

What it means

The test checks that the line's ram:SpecifiedTradeProduct, representing item information (BG-31), has no direct ram:ManufacturerAssignedID child.

Why it matters

EN 16931 provides the seller's item number (BT-155), buyer's item number (BT-156) and standard identifier (BT-157), but no separate field for this manufacturer-assigned identifier.

How to fix it

Remove ram:ManufacturerAssignedID from the exported product details. If this is also your seller's item number, place it in ram:SellerAssignedID. Otherwise, retain any useful manufacturer number in ram:Description (BT-154). Export the revised file and check it again.
