SAF-T › DUKIntegrator D406 errors

"The return type … does not match the declared period"

What it means

HeaderComment gives the return type (L monthly, T quarterly, A annual, C on request, NL/NT non-residents) and the period in SelectionCriteria must match: one month for L, one quarter for T.

Common causes

• L with a three-month period, or T with a single month.
• PeriodEnd lower than PeriodStart.

How to fix it

1. Set HeaderComment to match the reporting period (monthly/quarterly like the VAT return).
