This chapter covers the following topics:
A range of exception messages are provided in Oracle Manufacturing Scheduling so you can manage your scheduling by displaying jobs and resources requiring attention. Exception messages may be created after drop and drag scheduling on the Scheduler Workbench, after creating or scheduling discrete jobs, and after scheduling the entire shop floor.
For each exception that occurs, you can view the message, where the problem occurred and the severity, and details of the job. Messages can be one of three types: error, exception, or warning.
An error message indicates that the job was not scheduled as shown in this example:
Oracle Manufacturing Scheduling could not schedule job due to activity on this job while schedule was running. Please re-launch the scheduler.
An exception message informs you about a problem that should be corrected, but lets you know that the job is not cancelled as shown in this example:
Oracle Manufacturing Scheduling delayed the job because the requested start date is before today's date.
A warning message indicates an inconsistency, however the job is still scheduled:
The discrete job completes earlier than the requested due date.
There are several ways to view exception messages in Oracle Manufacturing Scheduling:
You can view exception messages for jobs or resources from the Scheduling Exceptions window. You can view the full text of the exception messages, delete messages, and mark messages to show that they have been read.
You can view exception messages for a single job or resource by accessing the View Exceptions window. Right click on any bar, a drop-down menu appears and choose View exceptions. This window displays in inquiry mode only.
This window displays information for all jobs and resources in inquiry mode only.
Exceptions window, choose Find to show all exception messages. Or limit the number of records by selecting criteria. See: Using Query Find, Oracle Application's User's Guide.
You can limit records displayed by selecting values for job, assembly, scheduling priority, job status, requested due date, scheduling request identification, or error message severity type.
Choose Find to display the Scheduling Exceptions window.
Select a job from the Tree Hierarchy pane to view exceptions.
You can view exception messages by either exception or properties.
Choose the Exceptions tab to view jobs by exception message.
In addition to the full text of the message, information is displayed in which operation sequence the exception occurred and the severity.
Optionally, you can mark a message to indicate that it has been read. Check the Marked box if you want to flag the message as read.
Choose the Properties tab to view the properties for the job that the exception message is flagging.
Note: In addition to the Scheduling Workbench, you can access the Scheduling Exceptions window directly from the Manufacturing Scheduling menu.
In the Schedule menu you can also access the View All Exceptions window. This window displays the same information as shown in both tabs of the Scheduling Exceptions window, in inquiry mode only.
