What is a primary function of the left column in the pattern designer?

The primary function of the left column in the pattern designer is to create, edit, and view steps for updates. In the context of ServiceNow's Discovery and pattern design functionality, the left column serves as a foundational workspace where users can define the various actions that should be taken during the discovery process. This includes setting up logical steps that dictate how data is processed and transformed, which is essential for ensuring that the configuration items (CIs) are accurately represented in the system following a discovery scan.

By utilizing this section of the pattern designer, users can streamline their interactions with the discovery process, allowing them to manage updates and apply specific logic steps that cater to their organizational needs. This functionality supports an intuitive design approach, allowing practitioners to visualize and manipulate the data flow efficiently.

While there are other functions associated with pattern design, such as data gathering, interaction with temporary variables, and analysis of existing CIs, the left column is specifically centered around the management of steps relevant to updates. Hence, its role is critical for updating and refining discovery patterns effectively.
