About Configuring the Has Task Revision Relationship

The Has Task Revision relationship family is used to link Task Revisions to Tasks. If a relationship definition exists between a Task family and its Task Revision subfamily, when you create a Task record in that family, the GE Digital APM system will automatically create a Task Revision and link it to the Task. The Task Revision serves as a historical record of the Task data on a given date and time. If you later update the Task, a new Task Revision will be created.

We assume that you do not want a Task Revision to be created when you create a new Task or update an existing Task. If, however, you do want these Task Revisions to be created, you will need to configure the Has Task Revision relationship to include the required families. No relationship definitions are configured for this family in the baseline GE Digital APM database.

The following table provides examples of relationship definitions that you might configure for the Has Task Revision relationship if you are using the root Task family or a customer-defined Task family.

Predecessor	Successor	Cardinality
Task	Task Revision	One to Many
Customer-defined Task family	Customer-defined Task Revision family (which must be a subfamily of the customer-defined Task family)	One to Many

Calibration Task Revision

We assume that you do not want a Calibration Task Revision to be created when you create a new Calibration Task or update an existing Calibration Task. If, however, you do want these Calibration Task Revisions to be created, you will need to configure the Has Task Revision relationship to include the desired families. No relationship definitions are configured for this family in the baseline Calibration Management database module.

The following table provides examples of relationship definitions that you might configure for the Has Task Revision relationship if you are using the Calibration Task family or a customer-defined Calibration Task family.

Predecessor	Successor	Cardinality
Calibration Task	Calibration Task Revision	One to Many
Customer-defined Calibration Task family	Customer-defined Calibration Task Revision family (which must be a subfamily of the customer-defined Calibration Task family)	One to Many

Inspection Task Revision

We assume that you do not want an Inspection Task Revision to be created when you create a new Inspection Task or update an existing Inspection Task. If, however, you do want these Inspection Task Revisions to be created, you will need to configure the Has Task Revision relationship to include the required families. No relationship definitions are configured for this family in the baseline Inspection Management product.

The following table provides examples of relationship definitions that you might configure for the Has Task Revision relationship if you are using the Inspection Task family or a customer-defined Inspection Task family.

Predecessor	Successor	Cardinality
Inspection Task	Inspection Task Revision	One to Many
Customer-defined Inspection Task family	Customer-defined Inspection Task Revision family (which must be a subfamily of the customer-defined Inspection Task family)	One to Many
