Hello,
You can delete the future PIR you have an option of Key date without reorganization period.
The key date refers to the to-date of the reorganization
OMP8 to mention the Period for requirements consumption only in some positive value.
Period which determines from which date that data is reorganized.This date is calculated by
subtracting the entered number of days from the current date. All data which is older than this date
will be reorganized.
Refer SAP note 135807 - Reorganization of planned independent requirements (Consulting)
