Example

The following example schedules a task to run the Job Queue Dispatcher and uses codeunit Job Queue Error Handler as the failure codeunit. The code requires that you create the following C/AL variable.

Variable	DataType	SubType
JobQueueEntry	Record	Job Queue Entry

TASKSCHEDULER.CREATETASK(CODEUNIT::"Job Queue Dispatcher", CODEUNIT::"Job Queue Error Handler", TRUE, COMPANYNAME, CURRENTDATETIME + 1000 + RANDOM(3000), JobQueueEntry.RECORDID);

To see this code in use, you can look at the C/AL code in codeunit 448 Job Queue Dispatcher in the CRONUS International Ltd. demonstration database.
