Untested:
insert into tblInjectLoans (lnkey, AuditorID)
select lnkey, AuditorID
from tblALPSLoans al
where AuditDate between @BegDate and @EndDate
and AuditorID in (
select lanid
from tblEmployees
where actiontype = 'ADDED'
)
and AuditType = @AuditType
and (select count(lnkey)
from tblInjectLoans il
where il.AuditorID = al.AuditorID
)
< (select round(count(lnkey) * @Percent/100, 0)
from tblALPSLoans al2
where al2.AuditDate between @BegDate and @EndDate
and al2.AuditorID = al.AuditorID
)
