Hello Gurus,
Can you please shed some light on how the planning happens with standard procedure . I have gone through the help document for Standard procedure with backward scheduling but could not understand much of it.
The helps documents mentions below.

Standard Procedure with Backward Scheduling
1. CTM shifts the demand date by one day into the future and attempts to fulfill the demand on this date.
CTM uses the search strategy and executes the source determination with this new date as the demand date. The way in which the system proceeds from here is dependent on the result of this planning step:
- If CTM can completely fulfill the demand on this date, the system ends the late demand fulfillment.
- If CTM cannot fulfill the demand completely or even partially on this date, the system continues with step 2.
- If CTM can schedule a partial quantity of the demand on this date, the system shifts the demand date by one more day in order to fulfill the remaining quantity of the demand.
If CTM can also schedule a partial quantity of the demand on this new date, then CTM shifts the date by one day again and again further into the future. CTM shifts the date again and again until the demand is completely fulfilled, or until the system can no longer create orders by shifting any further. A reason for this may be that the date falls at a weekend.In this case, CTM continues with step 2.
2. To determine a possible date for scheduling the demand, CTM now uses forwards scheduling. Starting on this date, CTM attempts to schedule the demand or a partial quantity of the demand with backwards scheduling.
3. If CTM can only partially fulfill the demand on this date, but not completely, CTM starts to shift the last determined date again, as described in step 1. If the system can no longer create orders by shifting the date further, CTM continues with step 2.
