If you make changes to multiserver job definitions outside Microsoft SQL Server Management Studio, you must post the changes to the download list so that target servers can download the updated job again. To ensure that target servers have current job definitions, post an INSERT instruction after you update the multiserver job, as follows:
EXECUTE sp_post_msx_operation 'INSERT', 'JOB', '<job id>'
To notify target servers that a multiserver job has been modified, you must invoke the preceding command after using any of the following procedures:
It is not necessary to call sp_post_msx_operation after you call sp_update_job or sp_delete_job, because these stored procedures post the required changes to the download list automatically.
The following are common tasks for managing jobs across an enterprise:
To check the status of a target server
To change the target servers for a job
To change the location of a target server
To synchronize target server clocks
To force a target server to poll the master server
