Why am I not able to change the voyage status from "Completed" to "Commenced"?

There may be an instance whereby you are trying to change a voyage status from Completed to Commenced and notice that the status keeps changing from Commenced to Completed automatically.

This happens when you have CFGAutoCompleteVoyage enabled and have entered the departure Date/Time for the last port of call for the voyage.

You can change this behavior by changing the value of the configuration flag to N.
