The Discharged at POD view shows containers
that are discharged and not yet picked up. Containers already returned empty have moved on and
correctly drop out of it.
If a container is missing from that view, check whether it has already been collected.
Example
A container you expected in Discharged at POD is missing after discharge. The view only includes containers that are discharged and not yet picked up, so once a container has been collected it correctly drops out. Check whether it has already been collected before treating the missing entry as an error.
