The effective date is used to represent when the shipment is really received (thus it may be diferent from the planned\_date). Having a planned does not mean that the shipment should be received on this date:  
For example I may have a shipment planned for yesterday but not received until today.

Normally Tryton expects the user to enter data is realtime, so when you do a move it’s effective date is set to today. But we allow the user to edit the effective date just in case he is encoding moves done in a diferent date.

I think this behaviour is correct and it should not be changed.

There is the plan to prevent [setting efective dates on the future.](https://discuss.tryton.org/t/user-mistakes-when-introducing-dates-in-different-forms/2738/5)
