Hi, Marlon,
No, save restoring from a prior backup (which would mean knowing when it still showed in the window and having to redo any work done in Payables since then, etc.), there isn't. Purging means just that - purged/deleted/cleared.
Nothing else comes to mind that might cause this other than, say, some sort of system 'hiccup' that occurred at the time of posting. It's possible that a different status might have been set for the check (eg. Void although we don't recommend this) but the process would be the same.
Is it that you're trying to reconcile to the bank? If so, you can simply take the amount of the check into consideration. If you want to see a report that shows the check actually existed, if they haven't been purged, you could reprint the posting journal (the correct posting sequence can be determined by drilling down to the transaction details in the Vendor Transactions tab), along with Vendor Transactions.
