From Clause for the Expand Businessobject Command

When you use the From clause, you expand away from the starting object. This gives you all of the related objects defined as the TO ends in a relationship.

Think of the starting object as the tail of the arrow—you are looking for all of the arrow heads .

For example, assume you have an object that contains a component used within larger assemblies. If you have the name of the component, you might want to know which objects (larger assemblies) it goes into: 

expand businessobject Component “Mini Numeric Keypad” C from;

This might produce a list of objects that could include a calculator, telephone, and VCR. Since no other criteria is specified, this command gives you ALL objects that occupy the TO end of a relationship definition.
