Redoing the changes in transport request

Hi All.

We have a situation in our landscape wherein we need to manually key in the changes moved in one of our landscapes to another landscape. So we have a set of Role transports. We now need to find out what were the changes that was made in each of these role transport to do them manually in another landscape of ours.

Can you ppl let me know if there is any way to check this. The maximum information that I could get was the role that was changed and when it was changed. Please help on this.

Regards,

Karthik
