Warning

CII-SR-066: Leave out the latest product data change date on a line

In short

Warning: worth checking.

CII-SR-066 warns that your line's product details contain ram:FormattedLatestProductDataChangeDateTime. Remove this element from ram:SpecifiedTradeProduct because the EN 16931 CII mapping does not use it.

On this page

What it means

This rule checks that a line's ram:SpecifiedTradeProduct element, the item information block (BG-31), has no ram:FormattedLatestProductDataChangeDateTime child. It does not check whether the date itself is correct.

Why it matters

The EN 16931 CII mapping does not include this product data change date element. This warning alone does not establish whether the invoice will be accepted.

How to fix it

Remove ram:FormattedLatestProductDataChangeDateTime from ram:SpecifiedTradeProduct on each affected line. If your software keeps adding it, ask your software supplier to omit it from the CII export. Recheck the corrected file.

Once the file is corrected, check it again for free: Validate an invoice against EN 16931

Or fix the invoice in a form and download the corrected file, for 1 credit: Fix a rejected e-invoice
