The Number of Lost Opportunities use case calculates the amount of lost Opportunities for each Account record. This use case deploys one Rollup Helper setting and one field, "rhuc_Number_Of_Lost_Opportunities." Once logged into your Salesforce organization click on the App Launcher or All Tabs and search for "Rollup Helper." Click on the "Deploy Pre-Built Rollups" tile and click Deploy next to the Number of Lost Opportunities label: ![Browse Use Cases Tile](https://www.passagetechnology.com/hs-fs/hubfs/Browse%20Use%20Cases%20Tile.png?width=1303&name=Browse%20Use%20Cases%20Tile.png) ![Number of Lost Opportunities](https://www.passagetechnology.com/hs-fs/hubfs/Number%20of%20Lost%20Opportunities.jpg?width=1752&name=Number%20of%20Lost%20Opportunities.jpg) - Click on the "Deploy Number of Lost Opportunities Field" button ![Number of Lost Opportunities deploy field](https://www.passagetechnology.com/hs-fs/hubfs/Number%20of%20Lost%20Opportunities%20deploy%20field.jpg?width=1750&name=Number%20of%20Lost%20Opportunities%20deploy%20field.jpg) - The Number of Lost Opportunities field will be deployed. - Please Note: Field Level Security will not be automatically set when creating fields through Rollup Helper, and the field will not automatically be added to page layouts. Please ensure that the newly created field is added to all desired layouts and permission sets once the rollup creation process has concluded. - Then click on the "Deploy and Run Number of Lost Opportunities Setting" button ![Number of Lost Opportunities deploy setting](https://www.passagetechnology.com/hs-fs/hubfs/Number%20of%20Lost%20Opportunities%20deploy%20setting.jpg?width=2267&name=Number%20of%20Lost%20Opportunities%20deploy%20setting.jpg) - Finally, click on the "Start Rollup Run" button ![Number of Lost Opportunities run rollup](https://www.passagetechnology.com/hs-fs/hubfs/Number%20of%20Lost%20Opportunities%20run%20rollup.jpg?width=2357&name=Number%20of%20Lost%20Opportunities%20run%20rollup.jpg) You will also be able to view and edit the deployed rollup via the All Rollups page.
