Define Data Granularity

Data granularity is the detail that is represented within your data, meaning that the more granularity your data has, the greater the level of detail within your data.

Data granularity can also have an impact when you are building relationships between tables in Power BI. For example, consider that you are building reports for the Sales team at Tailwind Traders. You have been asked to build a matrix of total sales and budget over time by using the Calendar, Sales, and Budget tables. You notice that the lowest level of time-based detail that the Sales table goes into is by day, for instance 5/1/2020, 6/7/2020, and 6/18/2020.

Power BI automatically detects relationships, but you can also go to Manage Relationships > New and create the relationship on the Date column. The relationship should resemble the following figure.
