let me elaborate more.
Im converting from XML to COBOL the no. of occurrences of one of the output message elements depends on an integer field in the XML input message. the output message is of fixed length. if I use Repeat Reference I have to define an integer field in the Output message and map it to the one in the input XML message but I dont want to do that since its not part of the COBOL structure I want.
Any suggestions |

is that repeating element always the last element? can they send it as last element?
if yes, you can just define it as complex element with max. occurences from the requirements. |

Do you *have* to model your cobol structure with CWF?
If so, this is what I've done in a similar situation: Model the data including the extra field. Convert the transformed data to a BLOB section. Use SUBSTRING on the BLOB field to remove the extra field.

No. You just put it on the queue as BLOB.
You can't model it successfully in CWF without the repeat count field. So you can't put it back to CWF after you've removed that field - which is your final output format, right?

Once a CWF message is written to the queue, it's been turned into a block of bytes - which is a BLOB. So all you're doing is making that happen a little early and then tweaking the contents.
So yes, it will work.
