BPM transformation multiline problem

[Former Member]

I have a transformation in an Integration Process. My Source Messages field points to a Multiline container element CollectDeliveries. My Target Messages field points to a non-multiline element SendShipment.

When I check the Integration Process, I get a red frame around the Source Message field stating that:

Expression must not return a multiline value.

If I remove the Multiline checkbox value of the CollectDeliveries container, the error disappears, but my CollectDeliveries container contains multiple Deliveries, so it is conceptually correct.

What could be going wrong here? Any clues?

Kind Regards,

Tony.

Anthony,

Check for your Interface mapping. It also must be Source 0..Unbounded and target 1..1.
