Dear all, Will some one help me in this issue please? We are entering the Zero Stock Component in Maintenance Order, and we make a Check when the order creator is going to release system will appear Error, until he will not delete that zero stock components from the Maintenance order. but right now what the order creator is not releasing the order but he is going to save order, when's he save the order without release system will generate Reservation in the back ground, which should not happen for Zero Stock Components ? I need the way which we are doing in MB21, Reservation creation by thru Cost Center / WBS Element. At present if you run MB21 and you are going to issue the material system will not allow to generate the reservation if there are zero stock components in the list. please guide me for this issue ?
