Production order basic dates (start and finish) in past

Hi,

My clinet has got one requirement where in they want to create an production order with past date (Basic start and finish). I found one way to achieve this by selecting the scheduling type as "Only Capacity requirement", but the disadvantage is that the order will not get scheduled.

Do you know any other method to achieve this functionality?

Thanks and Regards
