Errors when compiling version: Target structure & & does not match IDoc

What causes this issue?

The version compiler has determined the target structure (basic IDoc
type &v1&, extension structure &v2&) and found that the IDoc to be
processed (basic IDoc type &v3&, extension structure &v4&) does not
contain segments that belong to the target structure.

How to fix this error?

Please check that the target structure has been set correctly in the
outbound partner profiles.
