Looping for multivalued in power Bi report builder

Hi Aartibhilare ,

Thanks for reaching out to Microsoft Fabric Forum Community,
To meet your requirements ,you can use the following approach:
You can create Multi-value parameters, Create Conditional Report Views and Control Visibility Dynamically.

Step 1:  Create a Multi-Value Parameter
In your Power BI report, create a parameter (e.g., CompanyParameter) and check Allow multiple values. This will be linked to your slicer for selecting the company names.

Step 2: Add a Dataset to Fetch the Selected Companies

• Create a dataset (e.g., SelectedCompanies) to capture the selected values of the parameter.
• Use an expression to convert the selected companies into a comma-separated list for visibility logic.
  Example SQL :

                SELECT CompanyName

                FROM Companies

                WHERE CompanyName IN (@CompanyParameter)

Step 3: Create Conditional Report Views

• SingleView: For individual company selections.
• MultiView: For multiple company selections.

Step 4: Control Visibility Dynamically

• Set the visibility of the different report views based on the parameter.

For SingleView:

                            =IIF(Parameters!CompanyParameter.Count > 1, True, False)

For MultiView:

                           =IIF(Parameters!CompanyParameter.Count = 1, True, False)

Run the report and test the slicer selection,
