Plant ApplicationsAbout Disposing a Defect
A disposition is an action taken to resolve a non-conformance. The disposition method you select for a defect in Non Conformance determines the disposition plan for the defect.
A disposition plan includes the disposition, a description of the corrective actions to be taken (by using a hierarchy of actions), and any additional instructions to be followed to address the non-conformity. You configure the hierarchy of the disposition actions in Plant Applications Administrator, and then run a script file to link the hierarchy of the disposition actions for selection in Non Conformance.
The following table describes the available disposition methods.
| Disposition | Effect |
|---|---|
| USE AS IS | The serial/lot is acceptable for being used as is. |
| Continue to process (CTP) | The serial/lot can undergo operations up to the specified CTP
operation, at which point the defect can be addressed. Note: When a
non conformance is disposed as CTP to an operation in a mutually
exclusive set, then all the operations in that mutually
exclusive set will go on hold by default. |
| CLEAR | The serial/lot does not require any corrective action and is not considered defective. |
| SCRAP | The serial/lot cannot be used and must be scrapped. |
| REWORK | The serial/lot can be used after performing rework during a
specified operation. Note: In the list of operations to be reworked,
the excluded operations from the mutually exclusive set will not
appear. |
| MRB | The serial/lot must undergo review by the material review board before disposing it. |
Using Non Conformance, you can dispose the following types of products:
- Serialized: These products contain a unique identifier per piece (for example, a motor used in a pump). You can dispose a single defect or multiple defects for a serialized product at the same time.
- Non-Serialized: These products contain a unique identifier for a bunch of pieces (for example, a packet of screws). When you dispose a non-serialized product, you can select a different disposition method for different pieces in the same lot. You cannot dispose multiple defects for non-serialized products at the same time.
