BAPI_SALESORDER_SIMULATE condition value not triggering for smaller quantity

Hi all,

When I am executing the BAPI_SALESORDER_SIMULATE the output table ORDER_CONDITION_EX is not returning COND_VALUE for small quantites.

If I am executing the same with bigger quantity it is coming.

Eg: I want to get the volume discount,Invoice condition values from BAPI_SALESORDER_SIMULATE output table ORDER_CONDITION_EX .

      If I am giving bigger quantity as example 72000 Pieces it is returning all Condition values.If I am giving smaller quantity as example 7200 pieces or lesser it is not returning the values for Volume discount and On Invoice discount percentage.On Invoice value and Tax is coming fine for small and big quantities. I checked the same in VA01 where for small and big quantites all values are showing correctly in condition tab.

Thanks in advance,
