Final answer:
To use a manually entered hierarchy ID, one must update the specific system property to true, which is a setting often found in database management or enterprise software. The exact property name will depend on the system being used.
Step-by-step explanation:
The question pertains to a configurable setting in a software system that involves hierarchies, typically found in the domain of database management or enterprise software solutions. To use a manually entered hierarchy ID, the system property that likely needs to be updated to true is a property related to hierarchical data processing or object identification settings.
This could vary depending on the specific software platform in use. Changing such a property to true would indicate to the system that manual intervention in the assignment of hierarchy IDs is allowed and that it should not auto-generate or override these IDs.
It's important that when making changes to system settings, one must have a clear understanding of the implications it could have on the software operation and data integrity. Always ensure proper permissions are in place and, if possible, conduct this operation in a test environment before applying it to a production system.
