Documentation

Definition

The logging flag defines whether changes to the data records of a table should be logged.

Use

If you have set the indicator for logging, every change (with UPDATE, DELETE) to an existing data record by a user or an application program is recorded in a log table in the database.

Note:

If you have activated logging, this slows down accesses that change the respective table. The reasons for this are as follows:

• The system must write a record in the log table for each change.
• Many users access this log table in parallel. This could cause lock situations, even though the users are working with different application tables.

Dependencies

• Logging only takes place if the parameter rec/client in the system profile is set correctly. Setting the flag on its own does not cause the table changes to be logged.
• The existing logs can be displayed using the Transaction Table History (SCU3).
