Hi,

I am trying to read Group messages from an IBM MQ Queue through ITX MQ Client Adapter using -GRP2 command and its working.

-QMN QM1 -QN TEST -CD TEST.SVRCONN/TCP/127.0.0.1(1414) -HDR -GRP2 -REFRESH 60

However, I could see MQMD attached to each logical messages in the group.

As I need at read first occurrence of MQMD for my processing, how can we achieve fetch message without multiple headers ? If not possible in command, how can we handle it in typetree?

On the output side, a modified version of the standard mq.mtt Typetree can be used to read the messages, with only the 'Data' object being a repeating group.  Populate the header bit from the input side (with the header part of the output NOT being a repeating group, you will only get one occurrence) and then group to a functional map to map all the data parts.

Input             Output

  Message(s)        Message

    Header           Header

    Data             Data(s)   (=F_EachInMsg(Message:Input)

I hope this is clear

Thank you.

Paul
