Lock that does not allow other users to set simultaneous locks for the data in question. The
ABAP SQL statements
INSERT, DELETE,
MODIFY, and
UPDATE, SELECT
with the addition FOR UPDATE plus all corresponding
Native SQL statements or statements in
AMDP methods set appropriate
database locks on the rows they address. As an
SAP lock, an exclusive lock is set by calling a
lock function module with the appropriate parameters.
