I'm trying to understand a HealthScan finding for an Update Set. The scan result shows: "A table's elements are on compatible columns," but provides no other details.
What does this finding mean, How can I fix this came for referenced fields?
the message "A table's elements are on compatible columns" relates to how tables in an extended hierarchy can share the same physical database column. This mechanism is most notably seen with tables that extend the Task table, like Incident or Problem. It is a built-in platform feature that helps manage the underlying data structure efficiently.
The platform's table structure: In ServiceNow, tables can extend, or inherit from, one another. For example, the Incident table extends the Task table, and the Problem table extends the Tasktable. This creates a hierarchy where a single, physical database table (e.g., the base Task table) can store common field data for multiple child tables (Incident, Problem, Change Request, etc.).
