What is meant by Datasource Precedence in ServiceNow?

Datasource Precedence in ServiceNow refers to the order in which different data sources can overwrite data in the system. It is essential for ensuring that the most accurate and relevant data takes priority when multiple sources are available that may provide information about the same resource.

When establishing precedence, ServiceNow allows for a structured hierarchy where certain data sources are prioritized over others. In this context, a lower numerical order signifies higher precedence, meaning that data from a source with a lower number will replace data from a source with a higher number if both contain information about the same asset or configuration item (CI). This is crucial for maintaining data integrity and for ensuring that the latest changes or more accurate information is reflected in the ServiceNow environment.

Understanding datasource precedence helps administrators configure their discovery processes effectively, as it directly influences how discovered data is consolidated and managed within the platform.
