FIMS: Edit Report Warning: Voucher that Debt Memo is applied to had been moved to history - when posting debit memo

When posting a debit memo for a voucher, the edit report may contain a warning followed by an error.
 
 **W Voucher that Debit Memo is applied to had been moved to history.
 **E Debit Memo will cause Payable to go Negative. 

Answer:

This issue generally occurs if the voucher has been paid. The voucher will be visible in Accounts Payable > History. This alone doesn't prevent the debit memo from posting, but because the debit memo would cause the already-paid voucher to be negative, the error appears as well.
 
 If the voucher should be paid, the debit memo cannot be created.
 
If the voucher is paid incorrectly or shouldn't be paid at all, void the check and process the debit memo as usual.
 
*Note: If there should be a grant adjustment or cancellation, a debit memo will be created when adjusting the grant and should not be created manually in Accounts Payable after voiding the check. If this is the case, and a debit memo was created before the grant was adjusted or canceled, please see the steps here to remove this debit memo.
