3. What do the Groups stand for?
(Priority) Groups enable you to decide in which order the items will be loaded into the cargo space. Items in Group 1 will be loaded first, then the second group, then the third etc.
You can, therefore, influence the load plan e.g. depending on the order in which the final destinations will be visited by the truck.
Priority Groups can also be useful if you need to rearrange items in the load plan for some reason.
The algorithm automatically loads the largest boxes first but in some cases, this might not be the desired solution. Priority Groups enable you to change the order of loading items.
