Hi Nitin,
I am not sure I understand your question. But, the scenario you are explaining can't occur. If the ILM Object is not part of the Audit Area and you try to enter it (as you described above), you get an error
"No policy available" and it does not let you continue.
One thing to note is that rules are mapped to the ILM Object, not the Archive Object.
Best Regards,
Karin Tillotson
