Hi All,

I am trying to perform POC on flat file handling in IBM Hybrid Cloud Integration Platform. I created a flat file connector in IO Integration and then using the same I am able to create a flat file document in B2B tenant as well. When I am trying to route a sample flat file data from IO Integration to B2B using the "webMethods io B2B connector" service 'submit' , along with TN params [ TN_parms/SenderID , TN_parms/ReceiverID and TN_parms/DoctypeName] . The document is getting identified by B2B and processing rule invoked. However B2B is unable to parse the content of the document and throwing below error.

FFDocType DemoSubscriberFF encountered an error reading the document bytes.

FFDocType DemoSubscriberFF encountered an error reading the document bytes. Key "ffdata" is not found in the pipeline

Has anyone encountered this scenario? Please confirm.

Regards
Abir
