Fix BR-CL-21: Item standard identifier scheme invalid (ISO 6523)

BR-CL-21 in your own invoice? Upload the file and find every error in seconds.

What does BR-CL-21 mean?

The item standard identifier (e.g. a GTIN) needs a scheme from the ISO 6523 ICD list so that the source of the number is unambiguous.

Common causes of BR-CL-21

The short name of the identifier ('GTIN', 'EAN') sits in @schemeID instead of the four-digit ICD code.
@schemeID is missing entirely although a GlobalID (BT-157) is given.
An own item number was put into ram:GlobalID (it belongs in ram:SellerAssignedID).

How to fix BR-CL-21

Find the faulty spot in the XML. Open the XML of the invoice and go to field BT-157-1 along this XPath://ram:SpecifiedTradeProduct/ram:GlobalID/@schemeID
Apply the fix. Code the scheme of the item standard identifier (BT-157-1) in the @schemeID attribute with an ICD code from ISO 6523, e.g. '0160' (GS1 GTIN), '0088' (GS1 GLN), '0060' (DUNS), '0021' (SWIFT/BIC), '0177' (ODETTE). No plain text such as 'GTIN' or 'EAN'.
Validate again. Save the file and validate it again to check that BR-CL-21 is no longer reported.

Concrete fix

Code the scheme of the item standard identifier (BT-157-1) in the @schemeID attribute with an ICD code from ISO 6523, e.g. '0160' (GS1 GTIN), '0088' (GS1 GLN), '0060' (DUNS), '0021' (SWIFT/BIC), '0177' (ODETTE). No plain text such as 'GTIN' or 'EAN'.

XPath//ram:SpecifiedTradeProduct/ram:GlobalID/@schemeID

Before / after: the XML example

This is the spot in question before and after the fix (Cross Industry Invoice, ZUGFeRD/Factur-X).

Wrong

<ram:SpecifiedTradeProduct>
  <ram:GlobalID schemeID="GTIN">4012345678901</ram:GlobalID>
  <ram:Name>Kugelschreiber blau</ram:Name>
</ram:SpecifiedTradeProduct>

Correct

<ram:SpecifiedTradeProduct>
  <ram:GlobalID schemeID="0160">4012345678901</ram:GlobalID>
  <ram:Name>Kugelschreiber blau</ram:Name>
</ram:SpecifiedTradeProduct>

Frequent questions about BR-CL-21

Which ICD code do I use for a GTIN/EAN?

For the GS1 Global Trade Item Number use '0160'. For a GS1 location number (GLN) it would be '0088'.

Where does my own item number go?

The seller's own number belongs in ram:SellerAssignedID (BT-155), not in ram:GlobalID. Only the GlobalID needs an ISO 6523 scheme.
