That was the statement that I was looking for. I could not figure out why the scan was skiping records. Here is how it was fixed.

Use invfl in 0 shared order orderno
use orderfl in 0 shared order orderno

set relation to orderno into orderfl

sele invfl

Scan for shipdate=date() and empty(invfl.invno) and lines=1
lcCusnum=invfl.cuskey
lnOrdernum=invfl.orderno
lcCatkey=orderfl.catkey
If lcCatkey="CON" and orderfl.orderno=lnOrdernum
Replace hold with .T.
Wait window "Replaced Hold with True as Requested for Customer # "+lcCusnum at 15,115 timeout 0.75
Endif
Endscan
