Alerts and Most Common Alerts Report information Displays Blank

Question

Hello Sir,
Could some one help me on my Issue in SCOM 2012 R2.
Previously we use to generate all reports with out any issues, But very recently we had an issue while generating reports for "Alerts" and "Most common Alerts" Reports (from Microsoft Generic Library) its giving a blank with out any data.
Where in CPU, Memory, Disk Utilization are coming fine as expected. Only issue with "Alerts Reports"  and "Most Common Alerts Report".
Not sure how to proceed further to trouble shoot this issue.
Regards,
SA

Thank you Sir,
Previously all reports works fine, but recently we had issue only for "Alerts" and "Most Common Alerts" reports which is giving the blank DATA. Please find the below screen shot of the report.
