Why p sequencer

In reply to Rahulkumar:

Hi Rahul,

I would like to understand your statement “p_sequencer is used to access the environment component detail inside the sequence as sequence won’t have access to component detail/configuration etc.”

Could you give me an example where I can differentiate the difference between m_sequencer and p_sequencer? what kind of error I will get If I use p_sequencer instead of m_sequencer or vice versa.?

Thank you so much .
