I asked a question ( Lotus Notes 7 - copy / move docs. ( parent & response docs ) without changing the UNID ? ) and I received an answer which helped me a lot! Thanks Knut Hermann!
It works OK, it is an agent working on selecting documents. I was wondering if it's possible to create a schedule agent which runs one time per day? That means the user shouldn't manually selecting the documents and run the agent.
Thank you for your time and for your sharing info!
