Final answer:
In Excel, X would likely be the 'What-If Analysis' tool, found under the Data Tools section, and Y would be 'Scenario Manager', which is used to manage scenarios before creating a Scenario PivotTable report.
Step-by-step explanation:
In the series of clicks outlined to create a scenario PivotTable report, the term X refers to an intermediary step that would follow accessing the Data Tools within the Data tab in Excel, and precede proceeding to the Summary button and the subsequent options. It is likely that X is an action or a tool within the Data Tools that allows the user to specify or manage scenarios or models before creating a summary report, such as the 'What-if Analysis' tool, which contains various options including scenario management. Therefore, X could be 'What-If Analysis' and Y would logically be 'Scenario Manager' inside the process that ultimately leads to generating a Scenario PivotTable report.
X can be 'Scenario PivotTable report' in the series of clicks to create a scenario PivotTable report. After clicking on the Data tab, you need to navigate to Data Tools>X>Y>Summary button>Scenario Summary dialog box>Report type>Scenario PivotTable report>Enter cell name in Results cells box>OK.
