MF60 Material staging (Error E7021 by staging)

Hi,

I've tried to stage the components through the T.Code MF60. I get 100 pc in the storage location and I need 120 for my production order. I got an error(E7021) 20 pc shortfall.

I would like to stage the available goods 100 pc in spite of the difference and get a warm message instead of an error.

Thanks

Dede
