I would like to add a Brand field to the PartCatalog Entity, and I would like the user to select from a list of values in the ServiceBrand Entity.   In App10, we currently use an enumeration field but since there is a native brand field in the Request Management area, we prefer to use the native table.

When I try to add a field to the PartCatalog entity, I am unable to reference the ServiceBrand Entity.

Any suggestions?
