How to close service PO as completed

Dear Experts,

PR come from plan maintenance (service PO).

PO qty : 1 pc net price : RM1000

Service : 4 unit gross price : RM250 means each qtr

The issue here is user accidently create SE via ML81N for all 4 service qty instead of enter as 1. This caused to purchase order history shows SE & GR as RM1000 but user get correct inv & enter as RM250 in MIRO. So invoice stated as RM250 in purchase order history & others shows full amount.

Now user created new PO for remaining qty (3 unit) & wanted to close the above PO as completed. Kidly assist me how may I make this PO close instead of reverse IR, SE & SA. Please assist me. Thank you.

rgds,
