Load Planning 
You can plan the loading space of box trucks, trailers, semi-trailers, and containers in the transportation cockpit or directly in one of the following business documents:
Road freight order
Trailer unit
Container unit
Planning is carried out at the level of business document items.
Note
Load planning returns an approximate calculation of how the available loading space can be optimally used, taking into account the maximum axle loads and the maximum weight of a vehicle resource. The calculation is based on the master data that you enter for the resource. It is essential that you check the results calculated during load planning.
Prerequisites
You have installed SAP Visual Business. For more information about SAP Visual Business, see SAP Library for SAP Visual Business on SAP Help Portal under

Features
When you plan a road freight order on a box truck, trailer, or semi-trailer, the system takes into account capacity restrictions in terms of the height, width, length, and weight of the loading space. The same capacity restrictions also apply to the planning of a trailer unit on a trailer or semi-trailer. It also takes into account the maximum axle load of your box truck.
Furthermore, in the system you can add a split deck to your trailer or semi-trailer and consequently plan two decks.
When you plan a container unit on a container, the system also takes into account capacity restrictions in terms of the height, width, and length of the loading space as well as the total weight and the empty weight of the container.
In both the transportation cockpit and in the freight order, you can check the results of load planning as a 3D load plan or a table load plan in the form of a list of business document items. In the 3D load plan, you can show or hide individual objects as well as entire rows, columns, or stacks. The systems also provides you with information about the current load distribution and utilization of the loading space.
