Field help (SHIPSLAG2)

You can freely enter a difference in full days. This difference is considered when calculating the expected arrival date. This can be a delay causing the initially planned arrival date to be behind schedule.
When recording the shipment, the entered value increments the Total days difference. The time difference to be applied is reseted: you can enter a new time difference if needed.
If you wish to keep track of the applied time difference, enter this difference as an incident.
