SAP Database change logs - A simple solution for recording database change history

There is a very simple way to activate change history for database tables in SAP, including your own custom z tables. All you have to do is check the 'Log data changes' checkbox within technical settings.

Once you have done this and activated it you simply use transaction SCU3 to view any changes made to data within this table. There is obviously a very slight performace hit involved with doing this as logs need to be created each time a change is made so you probably only want to turn this on for tables you are interested in recording history for.

These logs are stored in table 'DBTABLOG' and can be access via function module 'DBLOG_READ'. Rather than me repeating what is already available on the web check out the following link for ABAP code on using this FM Using DBLOG_READ

SAP profile parameter rec/client
Also note you need to make sure the global parameter for for data logging 'rec/client' is set in-order to activate data logging to work. This can be set to be on for all clients, specific ones or set to off all together. See here for how to set the rec/client parameter.
