Hi @Zuah04881 ,
To avoid bringing unnecessary tables into their tables, you can create reports that use OLS
The color saturation option is no longer supported for real-time tiles. If you attempt to add the saturation, you'll be met with an error. The option should be left empty and the visual will work correctly.
Object-level security (OLS) enables model authors to secure specific tables or columns from report viewers. For viewers that don’t have the required permission, it's as if the secured tables or columns don't exist.
You can view the following documentation to create a report that uses OLS

To create a dataflow, launch the Power BI service in a browser then select a workspace (dataflows are not available in my-workspace in the Power BI service) from the nav pane on the left, as shown in the following screen. You can also create a new workspace in which to create your new dataflow.
Creating date dimensions in a data flow is a best practice that you can refer to
