Topic: How to correct old allocation errors

In a previous year, there were some errors made where some customers' payments were posted to the wrong sales accounts.  These were fixed with a journal entry.

Now, the effected customers all show un-allocated amounts due from the journal entry, yet have no other open transactions.
Whenever a new customer payment is received, FA attempts to credit the payment against the journal entries.

How can I correct/zero out these orphaned allocation amounts?  They are from a closed year, so I cant correct them by normal means.
Thanks

Re: How to correct old allocation errors

The journal entry should have been from the wrong sales account to the correct one. This should not affect the allocation of customer's  payments.

Re: How to correct old allocation errors

It was a journal entry from the wrong to the correct account.  But somehow, the customers effected all show balances from that journal entry that need payments allocated to them.
The problem is that it is from a closed year, so I cant correct it.
