Context other than entity

The future samples generated from this category are related to an action performed on a job.

Job Start

Future samples are generated for a job when it is started. If there exists an effective QM specification that,

• If the item context is not null, matches the main item being produced by the job, and

• If the operation context is not null, matches the job's operation, and

• If the item category context is not null, has a context of item category to which the main item the job produces belongs, and

• If the process context is not null and the work order to which the job belongs was instantiated from a process, has a process context of the process from which the work order was instantiated, and

• If the entity context of the QM specification it is not null, has an entity context matching either the entity on which the job is being run or one of its ancestors.

The future samples are generated for each QM specification at each interval time defined, and the context directly or indirectly matches the operation, item, and/or entity of a running job. If a characteristic is already accounted for by some other QM specification context having higher specificity than the current context, then it is ignored.

When a job is started and if the context is linked to a calendar frequency that has a start_delay configured, then the first sample after the job starts is delayed by the configured amount of time. The subsequent samples using calendar frequency will be generated based on the configured interval after delaying the first sample after the job start.

If a sample exists for a time frame linked to a QM specification context that has a lower specificity than the current context, then the existing samples are deleted before the new samples are generated for the current context.

When a shift change occurs, the future samples for the next shift are regenerated up to the end of the next shift. The regenerated samples are generated for item that is linked to a sample plan frequency and QM specification, and the context has the highest specificity than others.

Job End, Job Paused, or Job Status Change from Running to Another State

When a job is ended, paused, or the status is changed to any other state except running, the future samples for the sample plan frequency and QM specifications for the operation or item are deleted for the current shift. This is done as long as the operation and item are not used by other jobs on the same entity.

If the future samples related to the current context are deleted, new future samples are generated for the current shift. To generate the future samples for the current shift, the sample plan frequency and QM specification needs to have the closest specificity preceding the current context.
