P4021 does not appear correct for Planning rule C after MPR multi branch run (R3483)

Hello,

I ve a case where the supply and demand P4021 does not appears correct for a planning code C. I've set an plan horizon of 40 days, which means that the program should take max of Sales and forecast, in the month period of december.

In december I've a sales of 1170 pieces in 13 of december and a forecast of 1200 pieces in 29 of december.

The time series are correct becasue the planed order is 1200 in the month of december But the Supply and demand is wrong becasue the quantity is deducted Twice (for the sales and for the forecast).

Please have a look at the word attach for more information.
