What it means
The invoicing period (BG-14), or the period on a line (BG-26), sits in BillingSpecifiedPeriod and may hold only a start date and an end date. This rule checks that there is no ContinuousIndicator element, a yes or no flag that marks the period as continuous.
Why it matters
EN 16931 describes a period by its dates alone, so a file with an extra flag inside the period does not meet the standard. It fails and is rejected.
How to fix it
Delete the ContinuousIndicator element from BillingSpecifiedPeriod and keep the start and end dates. If the service runs continuously and the buyer should know, say so in an invoice note. If your invoicing software keeps adding the flag, check its e-invoice export settings for an EN 16931 profile, or ask its supplier.
