Custom Queries and authorisations

Hello,

I want to create a new specific report. I will create a custom CDS, then a custom query and finally a custom app. It works all right.

For instance, I've created an app to analyse the customer open items with some criteria available in the sales document.

Now, I would like to restrict the access to this data depending on some criteria. Let say that I would like to create athorisation profiles depending on the company code.

In the description of the root CDS i'm using, the documentation says:

To create the new app, I must specify a catalog. I look for a catalog that makes sense for this CDS: SAP_FIN_BC_GL_ANALYTICS_PC.

This catalog handles some restrictions types:

And I see no restriction type that would match the CDS prerequisites.

My question is: how will the system determine what data a user will be allowed to display? How the link between the CDS prerequisite and the catalog restriction types is made?

Thanks in advance for any enlightment you may give me.
