Attributes such as entity name, entity ID, date, duration, etc. which populate SAS report headings are also known as:

Dimensions are attributes or characteristics of data that provide context for metrics. In SAS reports, entity name, entity ID, date, and duration are all examples of dimensions because they describe what is being measured or when it occurred, allowing for data segmentation and analysis. Metrics, on the other hand, are the quantitative measurements (e.g., impressions, clicks, revenue). Delimiters are characters used to separate data fields, and advertisers are a type of entity, not a general term for these attributes.
