Not possible from ABAP. If you explain more about the context, maybe a different solution is possible.

Hi Hasan,

In table DD02T you can find all table names.

First copy this table to an internal table, then loop over it.

Check if the first character of the table name contains the 'S'.

If so, append these to a new table.

Then, for each table you can try to read the first line, if sy-subrc = 0, the table contains data. Otherwise, it is empty.

Be aware, this might take a very long time. There are over a million tables in DD02T. And if you want to check for many tables if they have any content, this would impose a lot of effort on your database.

Best regards,

Steven
