Scheduled jobs are located in the configuration object tree, in the Common branch. Each scheduled job includes two major properties: Method name and Schedule.
The Method name property connects the scheduled job to some procedure or function defined in a common module. When the job is started, the procedure or function is executed. It should contain a 1C:Enterprise script algorithm that describes the operations included in the job.
The Schedule property defines the execution periodicity.
In addition to the above properties, a scheduled job also has other properties, such as Repeat interval on failure and Restart count on failure. So if a scheduled job fails for some reason, 1C:Enterprise can run this job automatically for the specified number of times during the specified time period.
