ABAP Keyword Documentation → ABAP Glossary →Exclusive Lock
Lock that does not allow other users to set simultaneous locks for the data locked exclusively. The Open SQL statements INSERT, DELETE, MODIFY, and UPDATE, SELECT with addition FOR UPDATE as well as all relevant Native SQL statements set the corresponding database locks to the specified rows. As an SAP lock, an exclusive lock is set by an appropriately parameterized call of a lock function module.
