Refresh on Open is not working

Hi All,

I am using BO 4.1 SP 7. I am working on the existing reports. I enabled "Refresh on open" in the webi report(All reports in webi are pointing to Same Universe). But This Option is not working for few reports.

I tried all options like

1. Changing to Same data provider.

2. I even tried to create the report with same objects and Same filters(The new reports are working).

Please give the solution for the above issue except creating new ones.

Thanks in advance.
