I need to check if MQIIH exist in my message. I used
IF InputRoot.MQIIH is NOT NULL THEN
----- ELSE --- END IF;
But this always result in MQIIH is not there even if it is.
Is this the right way to do it ?

You can check to see if the first child of MQIIH is null.

You can check to see what the cardinality of the children of MQIIH is.

You can check to see if the list of children of MQInput root contains a field called MQIIH.

You can check to see if the field name of InputRoot.MQIIH is null.

Thanks Jefflowery, Fieldname works. I was just wondering why checking InputRoot.MQIIH does not work. MQIIH is an addressable field under Root as described under the dtructure of the message tree. This is more for my learning purpose.
