Differences between Exception 20 and 10 in MD04

[Former Member]

Hello experts,

Depending on the material, I have two scenarios:

Sometimes MRP says to reschedule the PO (message 10):

And other times MRP says to cancel a PO and create a new one (message 20):

Why does this happen? According to which data does occur one behavior or another?? Is there any value in the material master??

Thanks in advance.

Laura,

Exception message 10 generated because requirement on 28/07 but your firmed receipt is on 06/08 which is later than the requirement so as per rescheduling horizon system generates 10 to Reschedule in, if requirement is later than the receipt then system generates 15 to Reschedule out.

Please check SAP note 1745312  which explains about  Exception message 20 and Rescheduling horizon functionality.
