I have an input message in the NEONMSG domain (from an SAP iDoc output from the NEON SAP adapter) representing an invoice. I need to output a set of fixed-format records concatenated together into a single output message to feed a legacy back-end system; each single output message represents a single invoice. The number of records to be concatenated is variable, determined from the content of the incoming message. A back end process will take the single message and write the set of records to a file for processing.
My idea was that each of the record types can be represented as a message within the MRM, so I can get MQSI to construct a nice output bitstream, adding trailing spaces (all fields are character) etc. and it should be possible to do eveything within a single compute node.
No. Short of defining an output format in the NEON database, which we DON'T want to do, I have found no way of doing this.
I would dearly love to hear from anyone who knows how to do this! It's such a basic EAI function and I'm amazed it's proving so difficult.
Our environment is MQSI V2.0.2 CSD2, MQ V 5.2, developing on Win2K SP2 for (eventuallly) a broker on a Solaris box.
Thanks in advance - Cliff |

Sorted.
I created a message with a set of integer count fields at the front, followed by the other compound types representing each record type, made them mandatory & repeating counted on the value of the count fields. Constructed my output message in a compute node, RCD'd it to a BLOB then in another compute node created the output message as a substring of the input message, thus chopping off the count fields.
Hey presto, output message as desired. And no messing about with NEON stuff!
Cheers - Cliff |
