There are two scenarios where you might need to do this:

If the check has already been printed and posted, but it used the check stock from a different account than shown, do the following:
  1. Create a journal entry in General Ledger to move the payment from the current cash account to the correct one.
  2. Void the check, but do not create a debit memo.  Use original check dates.
  3. Change the historic voucher in Accounts Payable to reflect the correct cash account using the steps in the other scenario below.
  4. Process a new check with the old check number and date.
If the voucher has been posted, but the check not printed, do the following:
  1. Login to FIMS with the user id of "NPO".  You will have to find the password if not blank.
  2. Find the voucher in the History tab in AP.
  3. Navigate to the Line Item tab.
  4. Modify ONLY the cash account. Do not change the expense or payable account.
  5. Save the record.
Remember to log out and back into FIMS with your own username.
