All banks I've reported to require an AGED Payables listing as part of the monthly security requirement. The only way to generate this is to hold payables open until all Last Month(LM) AP invoices are posted and to use Manual cheque processing to print cheques but not post.
The Open Payables report gives a balance which will match our payables liability, but it is not aged. It may be too complex, but if the Aged Overdue Payables report was calculated AS AT a date which you could specify then this the program would save the extra work and occasional being in default of the bank requirements.
I currently have dropped the Open payables into an Excel spreadsheet and have been able to age. I submit this as a suggestion to the Aged Overdue report in some future update, but understand if there isn't a great deal of demand for this.
