stock requirement list/quantity discrepancy

Hi All,

I am facing one issue in stock requirement list.The schedule line quantity for a component material(ROH) is greater than the demand of dependent material(HALB) and that schedule line is accumulating whole months requirement whereas it should consider only weekly requirements as Lot size in material master is maintained as weekly lot size.

Can you please suggest why system is accumulating whole months requirements? What are the settings needs to be checked to clear the issue..

What are the factors that are considered at the time of required quantity calculation for any procurement proposals during MRP??

Regards,
