ServiceNow CSA Exam With Confidence Using Practice Dumps

When creating acustom table in ServiceNow, the platform automatically assigns a table name prefixed with " u_ " to differentiatecustomtables fromout-of-the-box (OOB) tables.

The default prefix " u_ " is applied to allcustom global tables.

The table name follows the format: " u_ " + [custom name].

Example:

If you create a table named " abc " , the system assigns it the table name:u_abc.

All custom tables created by usersautomatically receive the " u_ " prefix.

Prevents conflicts withServiceNow’s internal tables.

Ensurescustom tables are easy to identify.
