Query Regarding Variants

Hi

Suppose we create a job in client 300.This job executes a report in background that downloads data on to the application server.

As jobs are client-independent , we can run the job on any client.When we run this job in client 310, it is using the same variant that it used in client 300.

If variants are client-dependent, then how would this be possible??
