how to avoid conflicts while transporting a role

Hello,

Hope you people are having a great day!!

How to find out if there are any conflicts while transporting a particular role.

If a person A is transporting a particular role, and also his associate B has made some changes to the role. And assuming person B transports the role before, all the changes made by A will be overwritten.

How do we avoid this.

Thanks,
