During Logistics Order creation, the user is required to input both a Start and End Address for the header. The addresses available to choose from are dependent on which Operation the Logistics Order is being created in (shown with the Logistics Execution option in the drop-down). The list of available addresses is also dependent on the Customer selected for the Logistics Order (shown with the Customer option in the drop-down). The user can switch between Operation related addresses and Customer related addresses as desired.

Alternatively, if the desired address isn't already in D365, the user can create a one-time address by clicking the plus button next to the Name field. The created Address will be added to the customer for the associated Logistics Order. There is also a 'Search' option which will search the entirety of D365 for the desired Address.
Similar functionality exists when choosing addresses at the Logistics Line level. Logistics Execution and Customer addresses are available in the address pop-up (with the two drop-down options) as well as the ability to search and add addresses. Once the Logistics Order Header is saved (or the Lines are saved), the user will be unable to edit the address directly. The Change Address action will need to be used.
