1099 MISC for Being Generated for Non-1099 Suppliers

All:

We have a situation where the Clerk mistakenly entered ‘MISC7’ for our non-1099 Suppliers in TYPE_1099 column of purchase order line. The Closure Status is ‘Closed’. Unfortunately, 1099 MISC form is generated for these few suppliers. Is there a possibility to reverse the Closure Status or the Purchase Order line to change the TYPE_1099 code in order not to generate 1099 MISC form for these suppliers? 

Thanks,

Ernest
