The Batch Manager is used to trigger manual runs of Source or Platform jobs.

Manually triggering a Platform job
In general these jobs will only need to be run for maintenance or reruns if a batch fails.
In Batch Manager there is a Platform section which lists the jobs that can be run. Click RUN for the job you want to trigger.
A pop-up will appear. Click RUN to start the job. In some cases a date may need to be provided. KADA Support will advise when to set this.
