What could be a reason for Shipment records not being loaded if the integration runs every five minutes?

The reason that the integration could be failing to load Shipment records, particularly if it runs every five minutes, is that the integration process itself takes longer than five minutes to complete. When the duration of the integration exceeds the scheduled frequency, it can lead to overlapping processes, and subsequent runs could be attempting to start before the previous one has finished. This can result in data not being processed as expected, leading to gaps in the shipment records being loaded.

Thus, if the integration process takes longer than the designated interval between runs, it can create a backlog, where the system is unable to effectively handle the incoming data, resulting in missed shipments being loaded.
