You are able to contra off the original entries (credit note/negative payments etc) and allocate these contra entries off at the same year period and then re-enter and then allocate at the correct year/period you wanted.
Support can review to determine whether it can be amended or not but depending on how many transactions involved, there is no guarantee we can resolve for you.
Please provide as much detail as possible, including supplier code, audit numbers involved, if not provided this could delay the progress with your query.
Please note that if you have the Corrections module you can delete the transactions and re-enter and then you will be able to allocate at the required year/period.
