Hi @NishchalG ,
Usually we use IIF Fuction and Switch Fnction in SSRS to set the color, visibility, etc. of the report. Please see: Conditional Formatting for SQL Server Reporting Services Reports.
A report can have multiple data regions, but one data region corresponds to a dataset. If you want to obtain data from multiple datasets at the same time, you can use Lookup Function or LookupSet Function, etc. For more information, please refer to: Expression examples in paginated reports (Report Builder).
At the same time, we can use Subreports , Nested data regions , Drillthrough report and Drilldown action in the report. For more information, please see: Drillthrough, drilldown, subreports, and nested data regions in a paginated report (Report Builder).
