After exception registration, there is no person in charge, and the problem is easy to stay on the bulletin board. Allowing only registrants to close may slow down processing. The MES exception process should separate on-site control, cause analysis and processing confirmation, so that each step has clear actions and responsibility positions.

How to arrange records and operations

When registering, choose to affect work orders, equipment or batches, and describe the current restrictions. The processor will record temporary measures after receiving the order and suspend the circulation if necessary. The cause review and production resumption are confirmed separately. Measures and related records are retained during shutdown. Previous handling opinions can be cited for recurring exceptions.

Abnormal responsibilities should not be bound to only a certain name. The recipient should still be able to be found after the position changes. The registration interface can require you to select the current impact, such as production suspension, pending inspection, or restricted shipments, so that there is a specific basis for processing priority. When measures have been implemented but the effects have not yet been confirmed, the status remains pending verification. Recurrent exceptions must reference the original problem and record the scope of the impact. New events cannot be attached to the closed record and the new processing time limit will be lost.

Specific scenarios that need to be checked

The acceptance focus is on the situations of unaccepted orders, transfers and reopenings. When the handler leaves the post, the task should be able to be transferred to a replacement position. For quality-impacting exceptions, test whether closing the exception will incorrectly automatically release the batch, preventing the two approval boundaries from being mixed together.
