Purpose

A logging table is a table in the source system that records any changes to a table is being replicated. This ensures that SAP LT Replication Server can replicate these changes to the target system.

In general, for each application table being replicated, there exists a corresponding logging table. If changes occur to the application table, SAP LT Replication Server creates entries in the logging table to record the changes.

In order to replicate changes from the source system application tables to the target system, SAP LT Replication Server checks the logging tables to determine whether entries exist.

If entries do not exist, this indicates that no changes have occurred to the corresponding application table. SAP LT Replication Server proceeds to check the next logging table in the queue.

If entries exist, this indicates that changes have occurred to the corresponding application table. SAP LT Replication Server replicates these changes to the target system immediately, and proceeds to check the next logging table in the queue.

If all tables have been processed, SAP LT Replication Server provides different options for processing the logging tables again.

Under Utilities-> Specify Options for Logging Tables, you can specify the following options for how SAP LT Replication Server processes the logging tables:

  • Process all Logging Tables
This is the default setting. If you select this option, SAP LT Replication Server will process all logging tables again.
  • Only Process Logging Tables with Records
If you select this option, SAP LT Replication Server first performs a check to determine which logging tables contain entries, and then only processes these tables.

Example

You have many tables being replicated (for example more than 100), and changes are occurring to most of these tables. The option Process all Logging Tables is the most suitable.

You have many tables being replicated (for example more than 100), and changes are occurring to only some of these tables. The option Only Process Logging Tables with Records is the most suitable option. This allows you to reduce the number of data transfer jobs that process the tables, and still replicate to the target system in real time.

Additional Information

In the SAP LT Replication Server Cockpit (transaction LTRC), in the tab page Data Transfer Monitor, you can view whether the tables have been processed. An X in the column Loaded indicates that SAP LT Replication Server has processed the table.
