The reason why you might not see any or all pins in your Excel report is due to how the report creation is structured within docu tools. If you select pins as the basis for your report but use a template like "Excel Export Tasks," only pins associated with tasks will be visible. Pins lacking any assigned tasks will not be included in the report generation process. Consequently, if none of your pins have tasks linked to them, no pins will be displayed in the report. Similarly, if only certain pins have assigned tasks, only those specific pins will be visible in your report.
It's important to ensure that you choose the appropriate template that aligns with your initial selection of the report base, whether it's focused on pins or tasks, to ensure the desired content is included in the report.
