In support of an synchronous XI interface (SOAP->XI->RFC), I changed the underlying structure of one of the RFC parameters. I appended some fields to the end of a return structure in ECC. I re-imported the RFC meta data to the Integration Repository as always and mapped the fields accordingly. When I executed the interface, the fields that I added did NOT appear in the XML. This is because the XI runtime cache did not have the updated metadata for the RFC.
To update the runtime cache (called CPA Cache), enter the following URL in your web browser http://<host>:5<sys#>00/CPACache/refresh?mode=full. XI will do the rest of the work for you. After the CPA cache is refreshed, the new RFC meta data reflects the newly added fields.
These other CPA Cache URLs may also be helpful:
