Answer / rajesh chowdary pendyala
A "SAP lock" is named "enqueue lock", the enqueue is on a
much higher level, e. g. a complete sales document is locked
there whereas in the datbase usually only row locks exist.
Since SAP runs on more database than Oracle one needed to
have a mechanism, that is database independent and on a
higher level. sap locks can be viewed in sm12 and db locks
we can view in db01.

Answer / dj
Sap lock= sm12 lock on table/s while bring updated or modified.
Dealock/enaueue lock/db lock = db01. lock from db level by enqueue wp, so multiple instances in a landscape cannot access the db at the same time.
