Do I have to check the delivery and the data in the UDB within 72 hours after the supplier has made the entry and accept or reject the delivery?

The Economic Operator has flexibility to decide the trigger point at which the information is sufficiently available for the Economic Operator to introduce the transaction on the UDB except for PoS. Examples of such trigger points include an invoice, bill of lading, surveyor report of internal reference that links multiple evidence. These trigger points are to be linked to the evidence being shared with the auditor.
