InventUpdateOnHand class.

Hi All,

Can anybody please tell me whats the use of addOnHandCheck() method in InventUpdateOnHand class in AX 2009?

I want to know the significance of the above method, as the execution of this method is leading to some performance issue to our client. So, if anyone can give me detailed explanation of the use of this method and also the scope of its impact, then, I can think of either commenting this method or finding some work around. Kindly, reply at the earliest as this method is the standard code and we cannot just simply comment the code and give the solution to the client.
