What is the function of a Glide List field in ServiceNow tables?

The Glide List field in ServiceNow serves a specific function of storing multiple records in a single entry. This unique capability allows users to select multiple entries from another table to be displayed in a single field, making it an efficient way to manage and visualize relationships within the data. For instance, if you are associating multiple users to a single task or incident, a Glide List can facilitate this by allowing multiple selections, which are then displayed together instead of needing separate fields for each entry.

Other options may describe features of ServiceNow but do not capture the essence of a Glide List. A simple text field is characteristic of basic data entry and lacks the relational context that Glide Lists enable. Creating relationships between two tables typically involves reference fields or many-to-many relationships rather than the multi-selection capability of a Glide List. Lastly, summarizing data from related tables usually pertains to reporting functionalities or aggregate fields rather than the direct entry of multiple records within a single field configuration, which is the primary nuance of a Glide List.
