Question
What is the isolation level?
Answers
The isolation level defines whether and in which way locks are implicitly requested or d.
The selected isolation level affects the degree of parallelism of concurrent transactions and the data consistency:
The lower the value of the isolation level, the higher the degree of parallelism and the lower the degree of the guaranteed consistency.
If there are concurrent accesses to the same dataset, various inconsistencies (such as dirty read, non-repeatable read, and phantom) may occur at different isolation levels.
For SAP applications (ABAP stack), the isolation level is defined in the XUSER file. The ABAP applications run at isolation level 0.
In NetWeaver (Java stack), data sources are used for the application logon. These data sources can be configured using the NetWeaver. You can freely choose the isolation level. If the data source does not specify an explicit isolation level, default isolation level 1 (read committed) is used.   Your Comment
