Hello @Swapan
Welcome to eazyBI community! Thank you for raising this point. Currently there is no such feature, but we have discussed it before (you can read about it here - It would be good to have a inbuilt version control / Report changes history with EazyBI repors 5) as well as added it to ideas in the eazyBI backlog.
I added your vote to the improvement and will update this community post once there is any news regarding it.
Best wishes,
Elita from support@eazybi.com
