CII-DT-026: Remove previous revision identifiers from document references

In short

Fatal: fails the selected checks.

CII-DT-026 means a CII document reference contains ram:PreviousRevisionID. This element is not allowed on any document reference. Remove it while keeping the identifier of the document you actually need to reference.

On this page

What it means

Every CII reference element whose name ends in ReferencedDocument must be free of ram:PreviousRevisionID. This element identifies an earlier revision of the referenced document. The test has no exceptions.

Why it matters

This CII mapping has no field for an earlier revision identifier within a document reference. The rule does not decide which document version your invoice should reference.

How to fix it

Remove ram:PreviousRevisionID from the affected reference. Check that the remaining document identifier refers to the intended document, rather than automatically replacing it with the latest version. If you need to explain revision history, use the invoice note (BT-22). Export the corrected file and recheck it.
