ATP/CTP results and actaul dates are not in sync
Hi Experts,
We have unconstrained based ASCP ATP plan.
We have observed that based upon ATP/CTP results, there are some constraint shown ( resource constraint) because of which the request date is not fulfilled and new date is suggested as per the constrint resource availability.
Now next, when the SO is scheduled and a WIP job is created (by auto create final assembly program) it looks at SSD and schedules the work order operation, resource and components required dates backwards from SSD. It schedules the work resource and components to a different date than that of the actual results we have seen in resource availability. Due to this, the whole production schedule goes for a toss.
