You can use a local BOM as the basis for a global BOM.
Procedure
Add a local BOM to a Business Data project, using one of these methods:
Convert an existing local BOM project into a Business Data project: Right-click the Local Business Object Model project, select Refactor > Convert to Business Data Project, then click
OK.
Copy or move a local BOM into the Business Objects folder of an existing Business Data project.
Import an external model: Right-click the Business Objects folder in the Business Data project, then select
Database,
UML Model,
WSDL or XML Schema.
To convert a local class to a global class or case class, right-click the local class and select either
Convert to Case or
Convert to Global.
You can do this either from the palette, or from Project Explorer.
Delete any local classes that you no longer need.
Make any other changes you want, then save the BOM.
