This only appears if the job identified by Job Name has Allow Multiple Instance enabled. Enter a name for the invocation or a job parameter allowing the instance name to be supplied at run time

An 'invocation id' is what makes a 'multi-instance' job unique at runtime. With normal jobs, you can only have one instance of it running at any given time. Multi-instance jobs extend that and allow you to have multiple instances of that job running (hence the name). They are still a 'normal' job under the covers, so still have the restriction of one at a time - it's just that now that 'one' includes the invocation id. So, you can run multiple 'copies' of the same job as long as the currently running invocation ids are unique.
