AR Invoice has disappeared

Summary

An AR Invoice cannot be found, it has vanished

Content

We created an AR invoice dated 3/31/2019.  It was printed, reviewed, scanned, and emailed to the client.

But now it is not on Oracle.

If we search by the invoice # or the client name it does not come up.

I can't even see that it is possible to even accidentally, much less on purpose, delete an invoice without any trace.

Is it possible to delete an AR invoice completely?  And if so, how?
