You use transaction DB02 to determine the space used by each database table. You can sort the list as needed, such as by bytes used or by average daily growth.
The values for bytes used is only an approximation of how much space is reserved for a table. Depending on the database, the actual value may vary. This is why transaction DB02 may not be able to tell you how much space will be gained from archiving.
To determine this information, you can run a detailed analysis in transaction DB02 for individual tables. This requires the job COMPUTE STATISTICS be run in the background. This job can run for a long time; in extreme cases it may run for more than an hour.

For more information, see the documentation for the Database monitor.
