What must be done after modifying a pattern for horizontal discovery?

After modifying a pattern for horizontal discovery, the essential step is to save and bind it to a classifier. This process ensures that the changes made to the pattern are not only retained but are also associated with the appropriate classifier in the ServiceNow environment. Binding the updated pattern to a classifier enables the platform to correctly identify and classify the discovered items based on the modified parameters, leading to accurate data gathering and inventory reporting in the discovery process.

This step is crucial because patterns are directly linked to how the discovery process interprets and categorizes devices and applications within the system. Without saving and binding the new or altered pattern, those changes would not take effect, and the discovery results may not reflect the desired modifications, potentially leading to inaccurate or incomplete data.
