> When a deep create on a source entity follows a navigation property but no corresponding back-navigation at the target entity is found, AnnotationInMemoryDs throws the error "Missing source field for related data". There are two possible reasons no target navigation is found:
>  # It doesn't exist
>  # The target entity is of the same type as the source entity ("self-reference")
> *Steps to reproduce:*
>  # Checkout cars-annotation-archetype
>  # Remove property "Car" of entity type "Driver"
>  # Run example service
>  # Click "create example data"
> *Expected results:*
> Example data, including drivers, is created.
> *Actual results:*
> Car creation fails when it mentions a driver, no drivers are created nor cars that have a driver. Each create request logs "Missing source field for related data".
> *Workaround:*
>  # Always create a corresponding back-navigation property at the target entity of a navigation when using deep creates.
>  # Don't use deep create when target entity type = source entity type.
> *Additional information:*
>  # A similar fix as this one is already present in readRelatedData()
>  # Patch does not include a test (yet) for this special case. I would need some assistance regarding conventions and options.
>  # Bug was introduced in [6f7b76f689e4a8c8889c59760715c80d4a4c17f2|https://github.com/apache/olingo-odata2/commit/6f7b76f689e4a8c8889c59760715c80d4a4c17f2] of issue OLINGO-508. IMHO that change broke more than it fixed (expect at least one more related bug), but see #1.
