Activating Table Change Logs in the System. Transaction SCU3

You logged into the system to analyze table change logs (let’s assume that), using transaction SCU3, but received the following message:

A similar situation occurs if you choose the command Goto -> Change log in the SPRO context menu.

Let’s figure out how to enable these logs.

Modify the rec/client parameter for your system profile. This can be done via transaction RZ10.

An example of modifying the system parameter in the profile is presented in the note: Problems When Launching a WebDynpro Application.

The rec/client parameter can take the following values:

• ALL – if you want to activate logging in all available clients of the system;
• client1, client2, client3 – if you want logging only in the specified clients of the system.

N.B. Pay attention: using the ALL parameter may negatively affect system performance.

N.B. After making changes to the system profile, you must restart the application server.

See: REC/CLIENT Parameter in the System Profile
See: Setting Rec/Client Parameter for Logging

Check the results by launching transaction SCU3 for the table you're interested in.
