@kritib To run the Contribution Analysis you can right click on any line item in the freeform table in your project and then select Contribution Analysis option. A new panel of same will open up which will allow you to select the date range and dimensions for which you want to run the analysis. You can select the same and click on 'Run Contribution Analysis' button.
If this is not the case than can you please help me in clarifying the exact requirement ?
