When converting between two MRM message sets which each use CWF as the physical format, do the fields in the output MRM message have to be populated in the same order as they are defined in the message set?
IE:
If MRM2 has 4 fields: 1, 2, 3 and 4, and I use a compute node to map MRM1 -> MRM2 (using MRM2 as the message body and setting Properties.MessageFormat = 'CWF'), does this mean that I have to do:
SET OutputRoot.MRM.1 = InputRoot.MRM.1;
SET OutputRoot.MRM.2 = InputRoot.MRM.2;
SET OutputRoot.MRM.3 = InputRoot.MRM.3;
SET OutputRoot.MRM.4 = InputRoot.MRM.4;
and not in any other order?
I know this seems like a rather obvious question, but I would have thought that the broker would be smart enough to handle setting MRM fields within a compute node without imposing the strict 'Input messages in CWF format must be in the correct order' rule. |

You could populate fields in output message out-of-order if your output message's Compound Type is defined as Unordered Set. While writing out the message Broker will re-order these elements as per your output MRM message definition.
