What it means
Every CII reference element whose name ends in ReferencedDocument must be free of ram:EffectiveSpecifiedPeriod. The test has no exceptions. A referenced document's effective period is separate from the invoice period (BG-14).
Why it matters
This CII mapping does not provide an effective period within document references. A contract's validity period and the period covered by an invoice can be different.
How to fix it
Remove the ram:EffectiveSpecifiedPeriod block from the affected reference. If the dates describe the invoice period, record them in its start date (BT-73) and end date (BT-74) fields. Do not copy a contract's validity dates into those fields unless they are also the correct invoice period. Export the corrected file and recheck it.
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
