If you use Confirmed Delivery Date (EDATU) as the requirement date, the new requirement date is Material Availability Date (MBDAT).

The requirement date is calculated as follows:

New Requirement Date = [Requirement Date] – [Number of Working Days Needed to Schedule a Delivery]

For this sales order, the new requirement date is calculated as follows:

New Requirement Date = November 15 – [November 15 – October 15] = October 15

If you use Cancel Date (FSH_CANDATE) as the requirement date, the new requirement date is calculated as follows:

Requirement Date = Cancel Date – [Confirmed Date – Material Availability Date]

The system calculates the number of working days between the Confirmed Delivery Date (EDATU) and the Material Availability Date (MBDAT). This number of days is subtracted from the cancel date to determine a new requirement date. The requirement date for the sales order is calculated as follows:

Requirement Date = December 15 – [November 15 – October 15] = November 27

If you use Requested Delivery Date (VDATU) as the requirement date, the new requirement date is calculated as follows:

Requirement Date = Requested Delivery Date – [Confirmed Date – Material Availability Date]
