SEGW Runtime Artifacts: garbage removal?

Hy @ll.

've got a problem with the SEGW - SAP NetWeaver Gateway Service Builder.

- i used data sources from RFC.

- mapping the source to the entity first time: a ZIF_{rfc name} interface will be created.

- now i changed the mapping to another rfc function, the unused interface is still listed in the "Runtime Artifacts" tree.

Question: How can i remove this garbage from my SEGW project?

Another problem:

- i changed the rfc returning datatype from C(1) to C(2)

Question: How tell SEGW to update the datatype in the generated ZIF_{rfc name} interface,

or regenerate it with currently valid returning data structure?

Thanks, Danilo.
