Isn't there an XMS C version that could be used /called from COBOL?
Building a correct RFH2 in COBOL is such a nightmare..., Remember to check length and byte alignments and ... and ... and...

| No, unfortunately we do not have XMS C version. We need to construct in Mainframe using COBOL and send it to message broker. |

OK so why do you think you need to send the RFH2?

It is the requirement given to us to populate RFH2 header.
This requirement would help the message broker team to route the message without much code effort.
All these days message broker team were populating RFH2, now they want us to populate. |

That copybook doesn't appear to cater for the variable part of the RFH2. I'm guessing your message broker team will want the mcd section at least to guide the creation of the message tree.
Be aware there are rules on field placement in the RFH2 (byte alignment for one) you'll need to meet.

You should push back. This is something that the broker can do much more elegantly.

You should at least ask what information the broker team are using in the header. If, as is possible, they're not using the header at all but just want all messages to have one then it will be much easier for them to add it than for you to add it.
