Data is accessible via web client but not via perspectives

[ryan]

All of sudden users are unable to access the cube data via perspectives, but able to access the same via web.
Only admin id is able to access the data via perspectives, rest of the users are not able to access the cube data via excel templates.

- Old excel templates are not working in excel but working in web
- Newly created excel templates are working in both web and excel
- Old excel templates saved as new is also not working in excel but working in web.

What could be the reason.

I appreciate it if any one could help me in this.

Thanks in advance.

Have you made any changes to your Client Security Cube?
Any process/rule changes happen recently that might have affected your Group Security?

No, I haven't changed any thing. Until Friday evening it was working fine. But from the Monday morning it was not working. I have 5 TM1 modules. only one module which was meant to work on web(templates associated with this module used to work on both clients until Friday evening, but today the templates associated with this module is working only on web) is causing problems. Rest of the modules are working as usual. please refer the snapshot attached.
