Hey Chris,
It's not a problem. Just today I worked on Business Object Enterprise, Crystal Reports, MS Access, MS Project, Visual Studio, MS CRM, Javascript, HTML, TOAD, Oracle, SQL Server, IIS, Pro Tools....and Aware. It gets to be a bit of a brain scramble after a while.
As long as you have established the appropriate references between your objects you can display the data from another BO as a Shortcut.
Create a new attribute in the BO that you want to display a refenced object and select Shortcut as the attribute type. Then simply select the item from the referenced object that you want to display.
eg. Order BO create new attribute called ShippingAddressSC and add ShippingAddress.Address
Hopefully this will keep you on track.
Cheers
PEFS
