The Purge Closed Sales windows allow you to specify and purge the closed sales you want to remove from your Accounting Plus company file.
Before you purge information from your company file, be sure to print all reports that you wish to keep that show the closed information you plan to purge. You might consider printing a copy of the Sales Journal (Sales view of the Transaction Journal window), which contains detailed information about all sales.
We also strongly recommend that you make a backup of your company file before you continue the purging process. See Backing Up Your MYOB Accounting Plus Company File:
