If deleted from database with open-sql :
Not with Abap (even connectivity Abap), try asking database managers, they could restore date either from backup data (can be restored on another systel then copied back but with other number id) or by removing some journaled changes to the database.
If delete during Archive processing :
If you are lucky the data was saved (many objects) in a file on application server, maybe not yet destroyed - Look at SARA transaction object MM_EBAN.
If delete with standard transaction/BAPI/BDC
Alas Change documents wont help much if the flag "Doc. for individual fields at delete" is not checked (that is not the case by default) - look at SCDO transaction object BANF -> so go to first point
