What is the purpose of using comments in published data sources in Tableau?

Using comments in published data sources in Tableau primarily serves to provide additional context or descriptions for fields within the data source. By adding field descriptions, users can better understand the data’s purpose, its collection methods, and any relevant nuances that may impact data interpretation. This is especially helpful for those who may not be familiar with the data, as it aids in enhancing user comprehension and ensuring more accurate analyses.

Field descriptions can clarify how to use specific fields or highlight any limitations in the data, making the overall data set more useful and user-friendly. This helps maintain consistency and clarity across collaborative projects, as team members can refer to these descriptions to make informed decisions based on the information provided.
