How to find the history of users when they are in and out of a business role through dynamic role calculation?

HI All,

I have been looking how can I get the history information of any user who is being assigned/removed from a Business role via. a dynamic role calculation. 

When I click on "Reports - Overview with Business roles and user accounts(incl. history)" from the Manager application, I can only see the users active assignment to the Business role, but when the user is being removed from the

role, that information is not being visible in the "Reports - Overview with Business roles and user accounts(incl. history)"  report.

Could some one help me how to see the entire history of the user and his past assignments? Any config parameter that needs to be enabled.?

Note : We are using version 8.1.4.

Thanks and Regards,
