Database table protection or lock

Hello!

I need to protect a DB table from writing when my program in running. I have tried CF ‘ENQUEUE_E_TABLE’ and custom locks also, but these only work if the other programs do check the lock. If other programs start to insert/update/delete the table without checking the lock, they are executed with no errors or warnings. I tested it several times and checked in SM12 if the lock exists. So i need a solution to permanently protect the table from any writing, except the one that I executing.

Thanks in advance.
