We have issue related to material availability check for material in tcode MDVP. Actually when we are doing availability check for material in planned order (MD12) then it is successful but when we do the collective availability check (MDVP) then it does not work. Even we have stock for it but in collective availability checks it does not work.
In both cases there is same group and same rule. So please explain me what will be the reason
Please as soon as possible
