For example, using the baseline Cause Code record, consider a Primary Event that is linked to a GAA Unit with the value Miscellaneous (800) in the Unit Type field. In this case, the Cause Code System field in Event record will contain a list of each unique value in the System field in all Cause Code records with the value Miscellaneous (800) in the Unit Type field.
In an Event, when the Cause Code System field is populated with a value, the Cause code Component field will contain only values in the Component field in Cause Code records with a value in the System field that matches the value in the Cause Code System field in the Event. The Cause code Component field will not contain a list of values until the Cause Code System field contains a value. So in this example, if you select External in the Cause Code System field, the Cause code Component field would contain a list of the following values:
-
Catastrophe
-
Economic
-
Fuel Quality
-
Miscellaneous (External)
If you populate the Cause Code Category field, the Cause Code field will contain only values in the Code and Code Description fields in Cause Code records with values in the System and Component fields that match the values in the Cause Code System and Cause code Component fields in the Event. The list in the Cause Code field in an Event is displayed using the format Cause Code (Cause Code Description). The Cause Code field will not contain a list of values until the Cause code Component field contains a value. So in this example, if you select Miscellaneous (External) in the Cause code Component field, the Cause Code field would contain a list of the following values:
-
9300 (Transmission System Problems Other Than Catastrophe)
-
9305 (Ash Disposal Problem)
-
9310 (Operator Training)
-
9320 (Other Miscellaneous External Problems)
