Production Order Scheduling Basic start date in the past

Hi,

I have an issue in scheduling the production order in the forward scheduling. the scenario is like this:

I am trying to forward schedule the production order starting from today. But when the scheduling happens, the basic start date automatically go 1 day in the past. for example if today is March 30th 2016 and I use Forward scheduling in the CO01 screen with the basic start date as March 30th 2016 then after scheduling, the basic start date is automatically changing to March 29th 2016.

Please let me know the possible reasons for this.

Thanks

Regards

AK
