You are configuring a data column on a composite report.

In Workday, when you configure composite reports, you can map subreport prompts to prompt sets for greater flexibility. However, if theDo Not Prompt at Runtimecheckbox is selected on the subreport prompt, the prompt will not be exposed in theMap Sub Report Prompts grid. This is because Workday interprets the prompt as suppressed and therefore not available for mapping at runtime.

From the Workday binder:“Prompts suppressed with the Do Not Prompt at Runtime option will not appear in the Map Sub Report Prompts grid in composite report configuration. To map a subreport prompt, ensure the prompt is enabled at runtime.”

Other options do not directly cause this issue: default values on prompts do not suppress them, security issues would block data but not hide the prompt mapping, and prompt set configuration errors affect defaulting but not visibility.

Thus, the correct answer isB. The Do Not Prompt at Runtime checkbox is selected for the prompt on the subreport.
