Unallocated payment report omits partially unallocated

The "Unallocated payments" report is based on report view: "C_Payment_v UnAllocated" which has the where clause:

"NOT EXISTS (SELECT * FROM C_AllocationLine al WHERE al.C_Payment_ID=C_Payment_v.C_Payment_ID) AND DocStatus IN ('CO','CL') AND COALESCE(C_Charge_ID,0)=0"

This causes any payment with an associated allocation to be filtered out -- even if the allocation is only for part of the total payment value. So partially unallocated payments don't show up.

I think the where clause should simply be:
"DocStatus IN ('CO','CL') AND IsAllocated='N'"

The isAllocated flag is set when the payment is fully allocated or if the payment is to a charge.

(Historic bugs may have resulted in this flag not being properly set in the past. If this is the case the bad data should be fixed anyway.)

Any objections? Thoughts?

SQL script:

UPDATE AD_ReportView SET WHERECLAUSE = 'DocStatus IN (''CO'',''CL'') AND IsAllocated=''N''' where ad_reportview_id=155;
