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 ?

My vendor filled liquid oxygen in our 11000 liter capacity tank. He filled from 1400 MMWC up to 3200 MMWC. I followed the provided conversion table and found that we had been supplied 1800 MMWC liquid which is going to yield 2815 cubic meter. On the other hand, the vendor claims that he supplied as follows:- 5236 cub mtr(3200 MMWC)-2124 cub mtr(1400MMWC) = 3112 cub mtr. I fear that he wants to charge 297 cubic meters extra. He claims that my method was wrong and his was right. He says that this disparity is because of the conical shape of the base of the flask. I will be thankful if somebody can explain me the truth.
