For days I looked on the solution of this common senario of Componentization.
That is, in NWDI, in one SC, how to use another DC's component in consumer DC, most of the materials refer to use components in the same DC, and with my own try can not get right result.
My step is,
In the producer DC, put the Component to Public Part, with which the Component Controller Interface has been implmented.
In consumer DC, add Used DC (inactive) to DC Metadata->DC Definition->Used DCs.
Now is the problem, I think now I can find the external DC's component in the Diagram of the consumer component ( Choose 'Embed an existed component' to 'Used WebDynpro Components), but I can not find the external component.
This is my problem.
Please give me a hint.
