Ok. Have searched the posts and reading thru the manual. Pointers appreciated.

I import a.xsd with following parameters:
MessageSet: CRETIK_SOURCE
RootElement: MESSAGE
Result: Success

I import b.xsd with following parameters:
MessageSet: CRETIK_TARGET
RootElement: MESSAGE
Result: Error "Component Identifier Already Exists"

For testing purposes...a and b xsd are identical.

Obviously, I am still on the learning curve for using MRM...I can appreciate that messages within the same MessageSet can not contain the same RootElement but I can not understand why I am getting this error. I do know that the RootElement parameter is the cause of the error tho.
thanks

This is only occurring when the Root Element is "MESSAGE". "message" does not exhibit this behavior.

The Error Say what it mean.You should not duplicate the Identifier.

Check whether you had another element in the same message set with the same identifier MESSAGE.

And MESSAGE is different from message thats why its allowing you to check in with out any error.

Missam,
Thanks for the reply. I am defining only 1 message per message set.
My understanding is that MessageSets are distinct. That is, I should be able to have MessageSet CRETIK_SOURCE contain a message with a root element that is the same as a message that is defined in MessageSet CRETIK_TARGET.

My understanding is that you can't have 2 messages defined in the same message set with the same root element.

That's my understanding...I'm open to the possibility that I got this wrong..but I think my testing bears this out.

(wmqi2.1csd6 Test importing Identical schema files - barring modifications to RootElement)

TEST1:
MessageSet: CRETIK_SOURCE1
RootElement: MESSAGE
Result: Success

MessageSet: CRETIK_TARGET1
RootElement: MESSAGE
Result: Failure

TEST2
MessageSet: CRETIK_SOURCE2
RootElement: message
Result: Success

MessageSet: CRETIK_TARGET2
RootElement: message
Result: Success
