I recently ran into a new error when working through the Netweaver gateway. Because it was occurring on a new service, it left the door wide open to possible pieces I may have missed on the service. Well, after some digging, I realized that I had developed the service in one system, and was deploying it to a newer system. Since I had used structures, I bad the bad assumption that it would automatically update if the structure changed.
Well, it turns out, this is wrong. When SAP generates the service, it creates interfaces that take a snapshot of the structure, but they don’t use the structure itself. In the newer system, the structure contained 8 new fields, and until I generated the service in the new system, the service kept failing.
So, remember, structures used within a type in a Gateway Service are snapshots, not dynamic. So if you are having a strange error, sometimes it pays to regenerate the whole package.
