Cognos 10.2 ContentStore Database

[GeethaKL]

Hi All,

I am working on Cognos 10.2.2 and wanted to find out the cognos report version numbers after querying CMObjects table from cognos Content Store Database.
I expect the report version numbers will be the same for all the existing reports in all DEV UAT and Prod cognos.
But to my surprise the report versions appear different in all the environment though the modified date is the same.

Can anyone explain or provide some document on the version column  in CMObjects table and why is it different in different environments.
Thanks in advance

Regards
Geetha
