Manual reservations not getting deleted from APO

Hi ,

As per our business requirement we are CIFing manually created reservation from R/3 to APO. it got CIFed successfully.

Once we put FAINAL ISSUE indicatior in reservation its getting removed from APO.

The issue is some reservations not getting deleted from APO but we set final issue indicatior in R/3 for those reservation & there is NO DELETION FLAG for those reservation.......

i executed CCR but its not detecting those reservations........

what will be the issue?

Regards

Rajesh
