Q - By accident, I received goods and posted them on line# 1 of the PO when it was supposed to be on line# 2.Can you show me how to reverse it or correct it as line 2?

Generally speaking, it is a negative receiving --- make the ‘Quantity Received’  negative. Then make the rest of the fields identical to original value. In this case, you should enter QTY Received = -84, Line # 001, …… Post the transaction, and then make a new receiving (Line # 002).  See sample screen below:
