- Yes use a async sync bridge using corresponding adapter modules. There are quite a few documents on them on SCN.
- Use the adapter module message transform bean to convert xml to flat on tour receiver http adapter. This should be done before the adapter modules for the async sync bridge are configured.
- define a service interface with multiple operations for the 2nd async response flow. Depending on the response root tag PI will automatically process corresponding operation logic.
