Hi
Check log tables: ADOC, ADOx - maybe you'll be able to find your data there. You'll still need to take care about lots of things: header and lines for docs, reconciliation, accounting etc.
but this just as an emergency - as Frank stated: you broke the rules and cannot count on SAP support.
Maybe your database's recovery model is set to 'Full' - in such case you could be able to make restore to point in time. Otherwise do what Frank suggested.
Kind regards,
Radek
