Previous SEND failed

This occurs on a FEPI RECEIVE and is indicated by RESP2=216.

It may be an external communication error, or it may be that the back-end system has responded negatively (as IMS does, for example, if you try to run an unknown transaction). Use the FEPI EXTRACT CONV command to get the sense data describing the failure. If this indicates a negative response, you should reissue the FEPI RECEIVE to get the data. If it was not a negative response, it is equivalent to a lost session and the session cannot be recovered.
