IE, Excel and EPM compatibility issues

Hi,

We’ve one user who is having issues with input schedules in BPC ( As soon as a value is entered and moves onto next cell, value disappears). Same input schedules works for all users except this user whose PC has difference of 2013 excel. I’m wondering if Excel 2013 is compatible with BPC 10.1.

Also, we are seeing another issue on IE browser (IE 10 on BPC 10.1) caching of BPC web admin not displaying documents properly for the 1^st time (changing context to parent member shows document properly. Now, changing  back to the 1^st selected context also works so document doesn't show up the very 1st time). This issue is for all users.

For these issues, I’ve found SAP note 2113022 that talks about EXCEL and IE should be on same bit levels like 32-bit or 64-bit. Is this true and if not, it may cause these issues? Any other factors might be causing these issues.

Appreciate your help.
