In Workday Adaptive Planning, all level-assigned sheets - including standard sheets, modeled sheets, and cube sheets that have been configured and assigned to specific levels - are accessible through the Sheets section of the application. The Sheets area serves as the central hub for data entry and planning activities, presenting users with the sheets available to them based on their level access and permission settings. Users navigate to Sheets from the main navigation to find all planning input sheets relevant to their assigned levels. The Assumptions area specifically contains Assumption accounts for global rate and constant entry. Reports is for running and viewing financial and management reports. Modeling is the administrative area for building and configuring the model structure, accounts, and sheets - but it is not where end users go to view or access their assigned sheets for data entry. The Sheets navigation area is the correct and official location for users to access and interact with level-assigned planning sheets.
