MC46 Slow Moving Material

Dear Friends,

while i execute MC46 for Slow Moving Items.. Reports showing some material wrong data.. i generated for 30 days

HSD -- Showing data perfect 9 days no consumption ( after 31st 12 2011 no issues done.. checked thru mb51)

Brake OIl showing 30 days no consumption but when i check mb51 days before issues done..

is there any material specific or any configuration left.
