Hi! Running app9 and are trying out weighted average, transaction based we get some pricediff transactions as MPL vouchers instead of I and J when we've issued the received part to a repair shop order before the invoice is matched. 

On some of these transactions (PRICEDIFF) we get negative amount in debet/credit columns. I think this only occurs when we first issue qty to a repair order and then later do a return for credit, but i have never seen negative amounts in debet/credit in mpccom before and are a bit confused. 

Can someone please clarify when this negative amount is supposed to occur? Or is it a bug?

Thanks /Micke
