If you select Keep Transaction History in the P/O Options screen, the program keeps details of posted transactions until you remove them using the Clear History screen.
You can print Transaction Lists of the data—and reprint requisitions, purchase orders, receiving slips, and returns—until you clear the transaction history for them.
Transaction and Audit Reports
You can print transaction history on the Transaction List. All transactions you posted in Purchase Orders can appear on the list until you clear them using the Clear History screen.
You can also print the Payables Clearing Audit list for receipts you posted in Purchase Orders and invoices you processed using Day End Processing.
Transaction History Required for Drilldown
You must keep history to drill down from the G/L Transaction History screen in General Ledger, or from the Invoice Entry screen in Accounts Payable, to the originating transaction in Purchase Orders.
If you do not keep transaction history, Purchase Orders automatically deletes completed transactions when you run Day End Processing, and you will not be able to drill down to Purchase Orders transactions from General Ledger or Accounts Payable. More...
If you do not keep history, you cannot display or print copies of completed requisitions, purchase orders, receipts, and returns after you run Day End Processing, and you cannot look up the invoices, credit notes, and debit notes you posted before posting or running Day End Processing.
