How to true up payables subledger if we had to delete a journal in GL that was transferred

Summary: We had an issue where a user entered an invoice and then canceled the line and added new line with an accounting date for the next period which isn't open. Now there is a journal for these AP lines for April which is incorrect. We can reverse the journal in the GL but what do we do about the invoice? Its already paid and accounted we can't change the accounting date or override the invoice. Is there a way to create AP subledger lines to reverse april entry?
