You could use some sort of equasion to measure accuracy. Putting a code or letter for return type in the PO line on credit memos, would decifer wrong parts from other return types. Then make an english report on PDA.PARTS WITH INV# EQ "CM]" AND WITH CLOSED GE "date" AND LE "date" AND WITH PO EQ "your return code" BREAK-ON SLSMN
ect. ect.
compare each number of wrong part credit memos with total invoices and bam!
Of coarse that would require some honest counter people, and if accuracy is an issue, remembering to put something on the PO line would be an issue too.
Might just have to buy a six pack and do some scheming alone in the garage.
