In this scenario, once the Job message is created, a trigger
calling this Job can be generated.

1. In the MDM Repository
   tree view, under the Job Designs node,
   right click the message Job.
2. In the contextual menu, select Generate Talend Job Caller Trigger, accept
   the default options and click Generate.
   A trigger used to call the message Job is generated
   and stored under Event Management > Trigger. Its name is CallJob_Message, and its Service JNDI Name is
   callJob.
3. In the Trigger xPath Expressions area, customize the
   conditions of the trigger according to your needs.
   In this example, add the following conditions:

   XPath	Operator	Value	Condition
   Update/DataCluster	Matches	Product	C1
   Update/DataModel	Matches	Product	C2
   Update/OperationType	Matches	UPDATE	C3

4. In the Conditions area, combine the conditions using the
   predicates.

   In this example, enter the following:

   C1 AND C2 AND C3

   1	C1 AND C2 AND C3

   In this way, this Trigger will be executed on a record in the Update entity
   only when a Product data record has been updated.

5. Deploy the customized Trigger to the MDM server.
