Plan validation issues
If you encounter any obstacles while trying to advance your plan to the next stage using the Plan Progress Bar, it's likely due to a validation issue. There could be multiple reasons why your plan is unable to progress.
To address these issues, you can check the 
Validation issues tab, which provides a brief overview of the problems. By clicking on the relevant issues, you'll be directed to the specific problem areas for resolution.
Note
The validation issue will appear in the right-side panel only when a validation error occurs in your plan. If the plan is error-free, nothing will be displayed.
How to use the validation issue
If a plan contains an error, a
warning icon will appear in the right-side panel along with an indicator showing the number of issues.Click on the
warning icon. A list of all the warnings will be displayed.You can click on each issue to directly navigate to the problem and resolve it.
Once you have resolved the issues, they will be removed from the list.
Tip
Ensure that all validation issues are resolved before proceeding to the next stage indicated in the plan progress bar.
