HI,
I am new to this forum so not sure on the exact protocol or call signs.
Working on a problem set, I am transforming a SWIFT 54X message.
I got the SWIFT message parsed successfully using RCD.
The message folder structure after parsing is generated as:
InputRoot.MRM.FIN<msg contn.>
I am updating message fields and then need to add a 270 character length header at the beginning of message.
To do this I converted my header to Bitstream and now when I am trying to convert my transformed Swift to bitstream using the following:
DECLARE parseOptions INTEGER BITOR(FolderBitStream, ValidateContent,
ValidateValue, ValidateLocalError);
SET OutputRoot.BLOB.BLOB = CAST(ASBITSTREAM(OutputRoot.MRM OPTIONS parseOptions
SET OutputRoot.Properties.MessageSet
TYPE OutputRoot.Properties.MessageType
FORMAT OutputRoot.Properties.MessageFormat) AS BLOB CCSID 1208);
The issue I am facing is in the ASBITSTREAM function, the OutputRoot.MRM is coming as NULL.
When printing the Root element in trace, I can see the message present in the MRM folder. 
All the above operations - updating and adding header,is being done in a single compute node.
Please share your thought on why the MRM tree is getting NULL. |

MRM does not support FolderBitStream, to the best of my knowledge.
The only parser that supports FolderBitStream, to the best of my knowledge, is the XMLNSC parser.
The *correct* way to do this, however, is to create a new message definition that includes the extra header and the rest of the message.
Then just transform your input message into that message, rather than the one without the extra header. |

MRM does support FolderBitstream - it is quite a widely-used feature.

So you need to diagnose the problem. The best way to diagnose TDS problems is to take a debug-level user trace.

There are many, many reasons why this could be happening. Get a user trace, and you will be able to find out for yourself why this is happening. |

Hi and welcome. A protocol we have on here is to embed any code/output into forum [ c o d e ] tags, makes things more readable.
Cheers. |

Are you sure you should serialize OutputRoot.MRM with ASBITSTREAM function?

Apparently I've not used MRM in quite a long time. |
