ATP suggesting earlier arrival date than the requested date
Hi,
We are using ATP based on the planning data.
We have a sales order with 17-feb as requested date and delivery lead time is 1.
We don't have enough on-hand and so planned order should be created for this.
Request date type is Arrival in sales order. So, as per expectation, sch. arrival date should be 17-feb and ship date should be 14-feb as 15-feb and 16-feb are weekend holidays.
But ATP is returning 14-feb as arrival date and 13-feb as ship date.
I checked shipping, customer receiving and carrier calendars where both 14-feb and 17-feb are working days only. Not sure why ATP is suggesting earlier ship and arrival date.
