The Job Task table provides you with an overview of the job's economic status and provides usage information that you can use to compare with the job schedule.

Before you start planning a job or post usage on it, you must set up at least one job task in this table.

When you set up a job task, you enter basic information such as the description of the task and the job task type, which specifies the account type.

Each task must also have a job task number for identification. When you enter this number, for example, in a job journal, the information from the job task is used.
