SHEDULING  PARAMETER IN MAINTENANCE ORDER.

Dear All,

i am new to this community please suggest me regarding consumption order in iw31.

i have created a consumption order for regular consumption of materials in equipment.

suppose i created an order on 28.10.2012 and i gave the basic start date 01.10.2012, so accordingly my first operation start will be 28.10.2012. and i chose the component in component tab on same date(means 28.10.2012) so my requirement date will be 28.10.2012. and next day(29.10.2012) i chose one more component for the same operation. then my requirement date of previous component changes to 29.10.2012,

please suggest me so that my previous day reservation requirement date should be previous date and current date requirement should be current date.

thanks
