Authorization isssue on S_RS_COMP

Hi experts,

to grant authorization on querys there exists authorization object S_RS_COMP.

The field RSZCOMPID determines which components according to name a given user/role is allowed process.

Here my question:

is it possible to use variables instead of values and to fill the variables in customer exit/ABAP Coding?

Example:

Instead of

RSZCOMPID = "Z", "EG"

something likes

RSZCOMPID = $query

and query is filled via customer exit.

Thanks for your help.

Best Regards

Lothar
