This is usually not an error. Containers are reused across journeys, and the platform supports the same container number existing in several shipments. In most cases the earlier shipment is already deactivated and ther… --- ## [Why is my container flagged as not in the booking/BL and not getting tracking data?](https://community.dockflow.com/t/why-is-my-container-flagged-as-not-in-the-booking-bl-and-not-getting-tracking-data/170)

Dockflow checks the containers you supply against what the carrier reports for that booking or B/L. When a container is not on the carrier’s list, it is marked with the container not in booking/BL flag. That container… --- ## [Why do containers from another file appear on my tradeflow?](https://community.dockflow.com/t/why-do-containers-from-another-file-appear-on-my-tradeflow/169)

This is the most common cause of containers you did not expect. If more than one booking or B/L arrives on the same file, Dockflow tracks them all, and the containers from each are attached to the tradeflow. The sympto… --- ## [Why does a shipment exist but not appear in my Dockflow view?](https://community.dockflow.com/t/why-does-a-shipment-exist-but-not-appear-in-my-dockflow-view/153)

The shipment exists and has data, but it is not in your view. Dockflow deactivates a tradeflow once transport is complete, for example after the container has been returned empty, and dashboards filter to active shipme… --- ## [Why can’t I track my tradeflow reference if it never reached Dockflow?](https://community.dockflow.com/t/why-can-t-i-track-my-tradeflow-reference-if-it-never-reached-dockflow/152)

Here the tradeflow is not empty, it does not exist. Nothing can be tracked because nothing arrived. Two possibilities, and they are worth separating before anyone starts investigating: It was never sent.

Your account may have the setting “Do not import unknown containers from booking and B/Ls” enabled. With it on, Dockflow tracks only the containers you explicitly include in your upload, and ignores any other container… --- ## [Why is there no vessel name or ETA for my destination leg?](https://community.dockflow.com/t/why-is-there-no-vessel-name-or-eta-for-my-destination-leg/150)

A shipment can be tracking correctly and still show no vessel name and no ETA for the destination, because the carrier has only confirmed the earlier part of the route. A typical case: the carrier has confirmed the dee… --- ## [Why does my carrier return almost nothing at B/L level but answer properly by container number?](https://community.dockflow.com/t/why-does-my-carrier-return-almost-nothing-at-b-l-level-but-answer-properly-by-container-number/149)

Some carriers return a full transport plan when you ask by B/L. Others return almost nothing at B/L level: no containers, no milestones, sometimes only the port of loading and port of discharge. The same carrier will o… --- ## [Why does Dockflow show nothing when the carrier doesn't recognise my B/L?](https://community.dockflow.com/t/why-does-dockflow-show-nothing-when-the-carrier-doesnt-recognise-my-b-l/148)

This is the most common cause of a shipment with no data. If the carrier does not recognise the B/L or booking number you supplied, Dockflow has nothing to show. Three variants, all seen regularly: A mistyped B/L. A … --- ## [How should I report a merged shipment or a transhipment after the final port when the Console already classes it as an anomaly?](https://community.dockflow.com/t/how-should-i-report-a-merged-shipment-or-a-transhipment-after-the-final-port-when-the-console-already-classes-it-as-an-anomaly/147)

These are worth reporting: merged shipments, milestones in an impossible order, a plan that starts and ends at the same port, or a transhipment appearing after the final port. These have names and a definition - see an… --- ## [Why is a milestone shown on the carrier’s page missing in Dockflow?](https://community.dockflow.com/t/why-is-a-milestone-shown-on-the-carrier-s-page-missing-in-dockflow/146)

The carrier’s own page shows an event, the rest of the shipment tracks normally, and that one event is absent. Example A carrier’s page shows a milestone for a shipment. In Dockflow, the rest of the shipment’s events … --- ## [Why is my container shown in the wrong place when the carrier's location code and name disagree?](https://community.dockflow.com/t/why-is-my-container-shown-in-the-wrong-place-when-the-carriers-location-code-and-name-disagree/145)

Carriers send location codes and names that do not always agree, and some codes are valid identifiers for a completely different place. A leg routed through somewhere implausible for the trade lane is worth reporting; … --- ## [Why does the same event date keep alternating between the same values across updates without converging?](https://community.dockflow.com/t/why-does-the-same-event-date-keep-alternating-between-the-same-values-across-updates-without-converging/144)

Not a carrier revising its own estimate, which is normal, but the same event reading 24/03, then 30/03, then 24/03 again across successive updates, without converging.

A confirmed actual can still be revised. Revisions of a few hours after confirmation are common and are not a fault. Report it when the change is large - days rather than hours - or when a confirmed arrival ends up da… --- ## [Why does a Dockflow value stay behind the carrier page after repeated refreshes?](https://community.dockflow.com/t/why-does-a-dockflow-value-stay-behind-the-carrier-page-after-repeated-refreshes/142)

A value trailing the carrier’s own page for a while is normal rather than a defect - that case is explained here. What is worth reporting is a value that stays behind across several days, because that is the shipment n… --- ## [Why is a discharged container missing from Discharged at POD?](https://community.dockflow.com/t/why-is-a-discharged-container-missing-from-discharged-at-pod/134)

A routing can list a transhipment that the carrier later drops. The carrier’s own site sometimes keeps showing the original call for a while. A tradeflow can therefore show a leg that no longer happens, or show a routi… --- ## [Why did an actual arrival date change back after the carrier withdrew it?](https://community.dockflow.com/t/why-did-an-actual-arrival-date-change-back-after-the-carrier-withdrew-it/132)

Carriers occasionally publish an actual arrival or departure and retract it later the same day. Dockflow records what was received at the time, so a value can appear, then change back.

If a tradeflow shows an ETA you did not expect, check whether it belongs to a transhipment port rather than the final destination.

The flag does not by itself say the booking is wrong. It says the computed transport plan contains an internal inconsistency worth a human look.
