Determining Minimum Quantity as Percentage of Maximum Quantity in MAT1

Hello together,

is it possible that the Value for the field within /SCWM/MAT1 in Storaga type data "Min.Qty (%of Max. Qty) is determined by the system automatically?

I did the customizing "Define Storage Type Parameters for Slotting" and entered 15 in Max./Min. Qty.

After activating the values via /SCWM/SLOTACT it is not maintaining the value in MAT1.

Does somebody know why?

Thank you.
