Hope the above made sense. I have a message set using MRM with multiple messages. In a compute node, I am bringing in one of the messages (called contact admin). For example sake, contact admin has the following elements:
contact admin.firstName
contact admin.lastName
contact admin.address
Add this message to my Input in the compute node and drag and element from it to the ESQL area it looks like:
"InputBody"."firstName"
I need to create multiple instances of this record in this compute node - e.g.,
contact admin[1].firstName, contact admin[2].firstName, contact admin[3].firstName;
How can I say up multiple unique copies of this message - something like -
set Environment.Variables.contact admin = "InputBody"."contact admin";
set Environment.Variables.contact admin = "InputBody"."contact admin";
(not right I'm sure but this is kind of what I'd like to do)
How do I refer to this message specifically?
Thanks,
Melissa

Well first you have to tell MRM that this element repeats. This can be done by setting the Repeat property to Yes in Connection tab. WMQI can handle 2 types of repeat,
1. an Element repeats fixed number of times.
2. An element repeats "N" times, where "N" is an interger variable, which is defined before this repeating element.
Now create a Type/group element contact admin, which contains firstname, lastname and address, then create an element (contact admin) of this type.
Now create another type element RECORD_TYPE which contains contact admin element. Set the repeating property for contact admin element to true and set the repeat count to some number (or you could create an integer element and use value of for repeat). Your input message will be of this type.
In a compute node you could use code similar to this to store N records into environment tree.
SET Environment.Variables = InputRoot.MRM;
With this statement complete group element will get copied into Environment tree. If you want to refer to each repeating record's elements use following esql,
SET ..... = InputRoot.MRM."contact admin"[CNT].firatname;
where CNT = 1 to N.

Thanks very much for the info;
I'm not sure what you mean here:
"Now create a Type/group element contact admin, which contains firstname, lastname and address, then create an element (contact admin) of this type.
Now create another type element RECORD_TYPE which contains contact admin element. "
I have a compound type contact admin and a message of that type contact admin. I use the message in the compute node.
It sounds like I have to set the repeat property and do the following:
SET Environment.Variables = InputRoot.MRM;
SET ..... = InputRoot.MRM."contact admin"[CNT].firatname;
Or perhaps, I am missing something from the text I inserted above but did not understand completely.

You said:

Where is the Connection tab? I don't see one in the Compute node.
Thanks,
Melissa

Melissa,
Sorry if i wasn't clear enough in my earlier post. Connection tab is displayed for MRM elements under Message Set view.
You could set repeat property for an element, so you will have to first create an element of contact admin. Your message contact admin will be of some other type (RECRD_TYPE), as explained earlier it should also have an integer element to indicate how many times contact admin is repeating. so finally you will have these ..
Type : contact admin
contains ....
Elements: firstName, lastName, address.
create new element
Element: contact admin of Type contact admin.
create a new element to hold count ..
Element: RepeatCount (Integer).
now create a new type
Type: RECORD_TYPE
which will contain following elements in order
Element: RepeatCoun, contact admin
create a new message contact admin of type RECORD_TYP.
After you expand RECORD_TYPE element, click on contact admin element and then clcik on Connection tab in the message set, you could set the repeat property to true, in CWF tab set Repeat type to ValueOf RepeatCount element.
Your input data should always have counter in the beginning,
xxxxFNAME1LNAME1ADD1FNAME2LNAME2ADD2FNAME3LNAME3ADD3....
where xxxx is a 4 byte integer count.
