How to send Header value in Jmeter using ISO8583 Plugin
I was not able to send request message as per client requirement. Can anyone please let me know how to add header value to the request message as per below highlighted format.
VTS: ( Due to client confidential information, sharing first few lines of the request HEXDUMP)
00000000 **014F 0000 1601 0201 4F00 0000 0000 0000**
00000010 **0000 0000 0000 0000 0000** *0100 F224 6691*
00000020 *28F0 8216 0000 0000 0000 0020* 16XX XXXX
00000030 XXXX XXXX XX00 0000 0000 0000 1200 0821
I have attached Jmeter configuration for reference,
<isomsg>
<!-- org.jpos.iso.packager.GenericPackager[iso93binary_DPP.xml] -->
<header>160102014F0000000000000000000000000000000000</header>
<field id="0" value="0100"/>
<field id="1" value="F224669128F082160000000000000020"/>
</isomsg>
Jmeter HEXDUMP:
0000 *0100 F224 6691 28F0 8216 0000 0000 0000*
0010 *0020* 16XX XXXX XXXX XXXX XX00 0000 0000

Added screenshots for more clarity,
Added JMX as well for reference:

There are two places to define the header, at channel level, and at message level, the channel level header acts as a default header that is overridden by the message level header if present.
You need to specify the channel level header always, so the channel knows the expected length of the header.
This where you define that: 
If you need a specific header for a given message, you set it in the ISO8583 sampler, as follows: 
Keep in mind that the channel is the one interpreting the channel level header, and each channel will handle it differently, for instance the Base24TCPChannel will expect the plain string.
The message level header is always interpreted as a hex string. That's why in the example, the message level header has twice the length that the channel level's one.
If you need a more specific answer for your use case, please share the configuration you are using for your channel.
Here you have the jmx content, just save it as something.jmx and open it with jmeter.

Then you can just open a netcat server to check the header is coming.
➜ ~ nc -l 10000 | xxd
00000000: 0029 1601 0201 4f00 0000 0000 0000 0000 .)....O.........
00000010: 0000 0000 0000 0000 1800 0220 0000 0000 ........... ....
EDIT: With the info added by the OP, I ran the jmeter with the shared configuration and a server simulator, the server simulator is receiving the header as shown below:
<log realm="channel/127.0.0.1:49698" at="2024-08-27T07:08:16.651" lifespan="40ms">
<receive>
<isomsg direction="incoming">
<!-- org.jpos.iso.packager.GenericPackager[jar:packager/iso93binary.xml] -->
<header>160102014F0000000000000000000000000000000000</header>
<field id="0" value="0100"/>
Also, you can try it yourself with a netcat, I used port 10000:
➜ ~ nc -l 10000 | xxd
00000000: 00c5 1601 0201 4f00 0000 0000 0000 0000 ......O.........
00000010: 0000 0000 0000 0000 0100 7224 6681 28e0 ..........r$f.(.
00000020: 8016 0000 0000 0000 0000 1200 0821 0657 .............!.W
00000030: 2018 4566 2408 5999 8260 3930 3130 2020 .Ef$.Y..`9010
As you can see, the header is there also, so, the issue is most probably in an intermediate system, not in the jmeter config.
EDIT 2: It seems the problem is that you think that what is shown in the hexdump in the jmeter results, is what is the whole content that is sent over the wire; it is not, that is just what the packager is generating. The header and trailer are appended by the channel at send time, to really know what it is being sent you need to capture the stream. You need to listen with netcat, like shown above, or use a sniffer, like tcpdump or wireshark, or see what the other party receives in the log.
You have to also keep in mind that the channel will also send the message length, before the header. And the way in which the Base24TCPChannel sends the length is not compatible with what you expect, it sends just two bytes, and if you want the same as the VTS you may want to use VAPChannel instead.
A final note, there is a way for you to see the header (but not the length bytes) in the jMeter hex dump, but it is quite hacky.
There is an old packager feature, which I learned it was there short ago, by which you can specify the header length in the packager.
It doesn't work quite expected, and that's why it's a bit hacky. If you set that length and send a message over a channel, it will send the header twice, once added by the packager and once by the channel. You need to tell the channel to use an empty header. And then tell it to override with that empty header the header of the message (because it was already added by the packager).
To do that, you just leave empty the header in the Connection Configuration, and add a custom property in the advanced configuration with name override-header and value true:
And in the packager you add the headerLength attribute to the root element:
<isopackager headerLength="22">
