Alters - Delta Reports

Hello everyone, this is my first post in the community I am writing from Uruguay.

I’ve been using Openvas for a while now, and I’m facing the following problem that I’m trying to solve automatically to avoid endless hours of exports.

Here is my question:

I’m running alerts after each scan where if there is a new vulnerability compared to the previous report, I export the result to a .csv by SCP and so far so good. But I need the report to be filtered and only show me what is new compared to the previous report.

Is this possible?

I tried creating a filter (
delta_states=n ) and applying it in the alert from the Report Compose but it doesn’t work.

Thank you very much in advance if someone can help me.
