Getting error message " NJS-0121: Your parameters were saved but not added to My Reports since you have reached the maximum number of items" while adding reports under Home/Reports & Jobs and then accessing to desired report in the section "Parameters" (Save Parameters). In the new window, after you complete parameter name and enable checkbox "Add to My Reports" will receive the message error
Maximum number of reports that you can add under "My reports" is 10 as per design, Even though from the application UI we do not see any reports added under My reports tab, the reports are added in the database table.
Please check if your "MyReports" tab has already 10 Reports added then you need to delete one before you can add another one because the maximum you can have is 10.
