@noob Retro Bowl said in Problem with preparing a report:

Hello

I would like to create a report, but I don't know if it is possible to do so.
I've tried different ways but I can't do it.

We have organized the following data :

Virtual Machine
	|_Organization
		|_Asset owner
		|_Responsible for treatment

We would like to produce a report that allows us to :
Give all vms from an organization, where this organization is asset owner, but not responsible for processing

I've recently encountered this problem too. How can I fix it?
