does any one know what 'quit 0' will do at the DTL level? Does this retry the same message? Appreciate it.

May be set Failure time = -1 (at the REST operation component)?

Will that help, to keep retrying the same message until the connection is re-established with the external webservice server?

Thank you David. Yes, our incoming service does not stick with one HL7 message standard and varies from segment to segment. So we can create a custom schema to match the incoming messages structure but checking all the options.
