Thank you for the follow up.
I was trying to use an automation script because IBM support (via the case I opened) told me it was not possible to display information in the External message ID and Search ID fields if the payload was JSON.

Hi Gaétan,
I'm afraid this neat feature of using script expression is reserved to JSON payloads.
For XML messages you are really left off with XPath only.
Now getting to your key question why you cannot hook automation script to the MAXINTMSGTRK object lifecycle events?
The reason for that is Maximo standard performance optimization which led developers to skip MBO layer and script the data into MAXINTMSGTRK and MAXINTMSGTRKDTL tables directly.
It means that in general there are dedicated MAXINTMSGTRK/MAXINTMSGTRKDTL MBO classes but they are never in use when the actual message tracking is triggered.
Technically, even if you would try to go for Java customization, you wouldn't be able to achieve your goal either.
BTW: I suspect that you might have seen your Mbo#init() script called when MAXINTMSGTRK/MAXINTMSGTRKDTLobject was loaded for read purposes e.g. in the Message Tracking application.
To the best of my knowledge without rather nasty hacking - which I would NOT recommend doing - there is no way of getting more than MX standard offers.

Hi Andrzej,
I have been trying to achieve something similar to what Nandisha is trying to do. I even opened a case with IBM about this and their response was External message ID and Search ID could only use XPATH expressions, and theferore could only work with XML messages.
So as you did, I tried to do this using an automation script with an object launch point on the MAXINTMSGTRK object, on save, before save.
The problem I have is that my script never gets called.
I never see any event on the MAXINTMSGTRK object in the logs. I see multiple events on other objects, for our other scripts, but none for MAXINTMSGTRK.
The only way I was able to get my script to by executed (and see the event in the logs) was by configuring my launch point on the init event. And I really would prefer not to have a script on the init event for this objet.
This being said, I am really curious to know on which object/event you would configure your script's launch point.
Thanks for your help.

Hi Nandisha,
think of External Message ID or Search ID as a JavaScript expression which evaluates as one-liner to some value, preferably string in this case, where $ is a name of the variable which holds parsed JSON object (your input).
Having said let's consider few examples.
TIP: I used Automation Script to test this easily. This way you can experiment with your expression.
from psdi.iface.mic import EntMicUtilmsg = bytearray("""{"woactivity": [ { "description": "Task1 ", "status": "", "taskid": 1, "wonum":"********", "et_compby": "xyz", "et_compcomments": "", "et_compdate": "2", "et_complcode": "" }, { "description": "Task2 ", "status": "", "taskid": 1, "wonum":"@@@@@@@@", "et_compby": "xyz", "et_compcomments": "", "et_compdate": "2", "et_complcode": "" } ], "wonum": "xxxxx"}""", "utf-8")result = EntMicUtil.evaluateJSONForSrvMsgTrk("$.woactivity[0].wonum", msg)service.log_error("### RESULT 1: " + result)result = EntMicUtil.evaluateJSONForSrvMsgTrk("'TASK: ' + $.woactivity[0].wonum", msg)service.log_error("### RESULT 2: " + result)result = EntMicUtil.evaluateJSONForSrvMsgTrk("'TASKS: ' + $.woactivity.map(function(a) { return a.wonum }).join(', ')", msg)service.log_error("### RESULT 3: " + result)result = EntMicUtil.evaluateJSONForSrvMsgTrk("'WO: ' + $.wonum + ' / TASKS: ' + $.woactivity.map(function(a) { return a.wonum }).join(', ')", msg)service.log_error("### RESULT 4: " + result)
Here's the output:
### RESULT 1: ********### RESULT 2: TASK: ********### RESULT 3: TASKS: ********, @@@@@@@@### RESULT 4: WO: xxxxx / TASKS: ********, @@@@@@@@

Hello,
I need to configure "External Message ID" in enterprise service with JSON payload for Child Object attribute.
inbound JSON payload:
{
"woactivity": [
{
"description": "Task1 ",
"status": "",
"taskid": 1,
"wonum":"********",
"et_compby": "xyz",
"et_compcomments": "",
"et_compdate": "2",
"et_complcode": ""
}
],
"wonum": "xxxxx"
}
Enterprise service message tracking configure to display WOACTIVITY.WONUM in message tracking application
Please provide syntax to configure the child object attribute in ID field. Thanks..
