I'm facing some problems to access a Dashboard. This problem is intermittent and ,at the same time, one user can access and another get the error message "Cannot Access External Data ; Value of from=GetReportBlock_Sales_Dashboard_Gap_Analysis entered is incorrect.".
No changes were made on this Dashboard and since middle of last year everything runs Ok.
This dashborad uses QaaWs.
The BW query runs OK and no incorrect data was found.
All caches were cleaned.
Could anyone suggest what should I do?
