Thanks Tahir for your reply.
Just like to get some more info. DOE might be the tool which is used to create Data Objects.
See, in context of MBOs , we use Unwired workspace (as a tool) for creating MBO. But we use tables, web services and BAPIs(as backend components in enterprise explorer) which directly gets modeled as MBO. Do we have such concept for Data Objects that some existing objects in the SAP backend can be converted into Data Object? Or its a component that is created from scratch.
Hope my question is clear..
