zReport logic

Dear SAP Gurus,

my client needs to pull ot all the orders that is shipped from the existing zreport.

my plan is in the selection criteria there should be a check box for shipped , if the user click the shipped and execute the report all the orders that is shipped should come.

the existing field in the report is sold to party, ship to party,confirmed date,sales doc number, p.o number,cust mat info record,material id,requested date,confirmed date,commited date,,planned goods issue date,, delivery date , delivery number and plant.

pls let me know the logic from this existing report how to pull the orders that is shipped.

Awaiting for ur reply
