shared lock
Lock that allows other users to set further shared locks but no simultaneous
exclusive locks for the locked data. The
ABAP SQL statement
SELECT, without the addition FOR UPDATE, and the corresponding
Native
SQL statement or a SELECT statement in an
AMDP method do not set a corresponding
database lock for the rows in question by default. A shared lock is set as an
SAP lock using a call of a
lock function module with the appropriate parameters.
