I have imported the ESR/XI content for a (SAP-provided) SWCV into my ESR. It looks fine there. There is just one namespace. Some message types and data types are outside folders, all the interfaces and some data types are sorted into two folders (which makes sense, as there are two scenarios covered).
Now I look in sproxy in the ABAP system with that software component. I can see the SWCV, the namespace in it, the "unsorted" datatypes and messages types - and the two folders, but they are empty!
I'm mystified. What do I need to do to make the interfaces in the folders show up?
