CII-DT-070

Explanation

The invoice contains a detail that the data format knows but EN 16931 does not allow at that position, such as an extra qualifier on a field or a sub-field the standard doesn't provide for. This is an error in the software that produced the invoice, not a data-entry mistake. The invoice content may still be correct.

How to fix

Ask the seller to have the error fixed by their software vendor.
