Hi Rohit,
in the note 1678822 you will see that office 2013 is suppported, but over YES you will see a note number 5 described below 2013 is ok with bpc 10 sp10 and epm sp 14.
You mean if we have dimension files,templates and reports in one version then it doesn't matter if we have different Office version on client and server.
yes if the saved version is the lowest, thisgives youthe assurance that it works also with the highest version.
Regards
Roberto
