Getting R3 type

Hello colleagues,

I'm interested in a way to get the R3 type under NW platform, for exmaple, whether a system is a CRM, BW, PI, or any other kind of system available.

Is there a way to retrieve this information from the backend itself (using RFC for exmaple), or using the SLD repository to retrieve it? is this kind of information something a system provide upon itself? or one should figured it out of the deployed components in the backend?

Thanks,

Tomer
