Considering a customer that runs its business using several legal entities in D365 Supply Chain Management.
This customer will very likely organize itself with one team managing the containers for all entities.
Thus it is necessary for this team to have an overview of all PO lines & voyages (volume, weight, number or palets...)
As of to day, if you create one voyage in one D365-company, you can select PO lines from another company and add them to a stagging list. But you cannot finally add them to an existing voyage (although it is described in current documentation that it is possible, it will become an unsupported scenario)
suggestion: make it possible to add PO lines from different companies into one voyage/container, in order to have a central logistic team to optimize containers' filling with minimum efforts
