This blog post is intended to present a simple scenario of Backward and Forward Scheduling in action.
In this case, our Requested Delivery Date (RDD) is set to 24/06/2016. As shown in the above example, TDDAT was calculated to 21/06/2016 while doing the Backward scheduling. Since the date is in the past (date < RDD), Forward scheduling is triggered, resulting a new and final Delivery Date: 24/06/2016.
One important concept about this topic is Scheduling Schema: The given predefined set of date types and activities and their relationships are called Scheduling Schema. The supported Date Types are:
• ELDAT (Unloading Date) (only APO)
• LFDAT (Delivery Date)
• WADAT (Goods Issue Date)
• LDDAT (Loading Date)
• MBDAT (Material Availability Date)
• TDDAT (Transportation Planning Date)
I hope it gives you a better picture of the basics in Scheduling.
