ASCP Workbench buy item release with multiple buildings to deliver to

We have ASCP and EBS for two Operating Units.  One of our organizations has three buildings that are setup as a "ship-to" location.  Each building has a distinctive physical address.  We have suppliers that need to ship different parts to potentially all three ship-to addresses.

Each item is assigned to at least one BPA that has the ship-to location assigned. 

Each item has an ASL that assigns which BPA and BPA line to use.  The ASL "release method" is usually set to Automatic/Approve.

Each Item has a sourcing assignment for the supplier of the BPA we assigned in the ASL.
