Reallocating to Offer Set or to World

Depending on the system actions a user holds, they may be able to reallocate a work item more or less widely.

For example:

reallocateToOfferSet - This system action authorizes you to reallocate a work item to a resource in the original offer set. If for example the originally allocated resource is absent or overloaded, this might typically be sufficient to reallocate a work item to another member of the same team.
reallocateWorkItemToWorld - This system action authorizes you to reallocate a work item to any resource—that is, to anybody in the "world" of the BPM runtime. You might need this level of authorization if for example it was decided that a work item needed reallocating to another department or to a resource with significantly different expertise, who was not in the original offer set.
