SNP Planned Order Date Issue

Hi All,

Planned order created by SNP run (Heuristic) always has start and end date same.

The same planned order when hit the ECC, it get rescheduled and has different start and end date.

Example:

Planned Order           Start Date                    End Date

     In APO                    31/10/2013               31/10/2013

     In ECC                    29/10/2013               31/10/2013

In PDS, activity duration (fixed) is 1 day and I believe it could be the reason.

ECC, calculates the correct duration (Actual Order Quantity*Standard Activity Hours in Recipe / Base Quantity) and schedules the order.

How the activity duration (fixed) figure populates in PDS?

Please provide the info what could be the reason for SNP planned order have always similar start and end date.

Let me know if required any information to undersatnd the facts.

Regards,

Deepak
