Cascade Update function
The Cascade Update function enables you to update a configuration item (CI) attribute in the Telecommunications Network Inventory application and cascade the change in all related CIs. You can use this function to automatically cascade the field values in related CIs when you use Workflow Studio.
You can use the Cascade Update function to update any field in the inventory record and cascade the changes all the way down to the hierarchy mentioned in the inventory record.
If there’s a conflict, such as any discrepancies found in the related CIs, this function returns an error. For example, let's say that you pass the change request and CI but the CI isn’t added to the affected CI list of the change request. Instead, it returns a sort error with the conflict information in execution.
Note: This function doesn’t work on Life Cycle Stage and Life Cycle Status fields.
You can use this function as a Workflow Studio action in the Telecommunications Network Inventory workflow.
Roles and availability
