Object documentation Isolation Level 15 Locate the document in its SAP Library structure

The following rules apply if isolation level 15 is specified:

For all SQL statements, the behavior described for isolation level 1 or 10 also applies for isolation level 15: The only difference is that, with isolation level 15, shared locks are requested for all the tables addressed by the SQL statement before processing starts. When the sql statement generates a result table that is not physically stored, these locks are not released until the end of the transaction or until the result table is closed. Otherwise, they are released immediately after the sql statement has been processed.

When rows are inserted, updated or deleted, implicit exclusive locks are assigned to the transaction for the rows concerned. These cannot be released until the end of the transaction.
