Three invoices (for staggered payments) were created for three separate ticketing orders. Invoice #1 was for £3520. Invoice #2 was for £1020. Invoice #3 was for £570.
One of our staff members opened the order of invoice #1, and using CTRL+G, processed payments in the customer record of £590 (#1), £340 (#2) and £190 (#3).
As a result, all of the payments seem to have been processed in order #1, although the record of the payments is also across orders #2 and #3. To be specific, order #1 is showing:
Order #1 has £530 outstanding balance (the sum of the invoice payments of #2 and #3). Orders #2 and #3 have negative balances of their respective invoice payments.
I can't return any of these balances to account, or create new invoices out of them to try and pay them off, without encountering this error:
This error occurs on all three orders, with the amounts mentioned differing depending on the order and what you try and do with it.
Can anyone advise anything? I've tried returning the amounts, creating invoices, and nothing works without leaving this error, which means none of my attempted changed can be saved.
Thanks.
Ouch. This looks like a bug. I would advise submitting a ticket to TASK, since it sounds likely that there will need to be some manual SQL updates to resolve your issue.
