Which fields can be configured in reporting to perform arithmetic, coalesce, concatenation, and length?

'Sourcing fields' refers to the original database fields from which report data is drawn, not a type of field that performs calculations itself.

Function fields enable users to create virtual fields within reports by applying database functions such as arithmetic operations, coalesce (handling nulls), string concatenation, and calculating string length to existing fields, enhancing reporting capabilities without altering the database.

'Computational fields' is not the standard or official terminology used in ServiceNow for fields with these specific data manipulation capabilities.

'Calculation fields' is not the standard or official terminology used in ServiceNow; 'Function fields' is the correct term for this reporting feature.
