Beginning Availability in time series showing incorrect on hand

Hi Team,

I have observed that for potency controlled items, when I ran MRP R3482 for material planning, the beginning availability in time series showing incorrect quantities.

Further on my anlaysis ,I found that on-hand qty is getting multiplied with Lot potency value and that quantity is shown as on-hand in BA.

Any setup to avoid this calculation. So that MRP will consider the actual on hand for planning and generate message.

I am expecting the OP messages but because on hand qty is multiplied to lot potency value

system not generating any supply messages considering the on hand at the higher side of demand which is not true.
