after moving to B2B toolkit 2.0 I'm facing an issue for processing the 997 x12 received from customers. The error from the Receiver EDISeparator is
Message could not be forwarded to the JCA adapter. Reason: while trying to invoke the method com.sap.aii.adapter.ediseparator.ra.x12.AcknowledgementMessage.getInterchangeSenderID() of a null object loaded from local variable responseMessage
The process is that the 997 is received and translated into an ALEAUD message was working on Toolkit 1.0 . We're not using TPM.
