What causes this issue?

You have tried to create a finish-time event. The system ascertained
that for an existing start-time event on &V1& at &V2& there is a
missing finish- or interruption-time event.

How can this happen?

The following time events exist in the system:
Start processing 8:00
Partial finish processing 9:00
Start processing 13:00
If a "Finish processing" with 15:00 is to be created then this is not
permitted since a time event is missing between 9:00 and 13:00 which
represents the end of the time period that started at 8:00.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
