1. Yes, it should be like that, as there are other systems where the configuration is like that and the task works perfectly. I will change to see what happens

2.Yes, same as above. Although, I will change it too 

3. That is because through the Task Schedule tool I manually executed the task after son changes. 

Hello Vitaliy, as I said to Yaron, I've granted to the user all kind of rights but it continues like that. I've also change user to Administrator but nothing has changed. It seems it is also not related with the user who runs the task.

I will take a look, thank you :)

I will check, thank you :)

Yes, it's a namespace and a task created by me. The thing is that it works normally in my own database or in other PCs databases, but not in this particular one. That cache task PurgeAudit works also with this database, but as you point, this is for the namespace %SYS and not other one than that.

Hi Vitaliy. I forgot to say that the audit logs are in other namespace called "ACB". Whatever, I also tried to delete the logs manually via SQL and it works. There is something in the task itself or the DB preventing the task to have a normal behavior. I have updated the main post with the task configuration, so anyone can see if there is a problem there.

Thanks for your help,

Pablo.
