Use parameter maps in security filter

[arwol]

Is it possible to use parameter maps in a security filter?

I have a query subject which contains data about company numbers.
I have a parameter map in which I have usernames and company numbers for which they are authorized.
I would like to create a security filter in which I filter on the company number, so that users can see only the company numbers for which they are authorized.

I tried a lot of things, but I still cannot find out what I have to do.

Can anyone help me on this?

Thanks in advance
