Difference between roolup,hotfix and service pack

Hi All,

Could you please tell me…

What is the difference between roll up,hot-fix and service pack?

Thanks in Advance,


Roll up is like an update patch which we use only for Retail Ax.

Hot fix - If any specific bug is there and the customers complaint about it, MS will release an update patch only for respective bug which is called as Hot fix…

Service pack - Some newly added features are there also cover some previous bugs…

Thanks and Regards,


Thanks for giving replay
