Free indicates that there is no expectation that the load will be tendered or moved in its current state (that is, user is "Free" to fully dismantle the load). The implication is that no commitment has been made either internally or externally based on the current load composition.
Loads in Free Planning Status must be in Open Operational status.
Loads on Trips cannot be in Free Planning status.
Loads in Free Planning status are not eligible for re-planning (that is, not eligible for optimization). The expected workflow would be for users to use the Select Load's Shipments for Optimization operation to destroy Free loads and immediately enable the associated shipment legs for optimization.
