Hi Jeff,
the information about software components (and this is I think what you are looking for) is stored in the LMDB of Solution Manager. Each satellite system sends its component info into SLD (either in an external system or in Solution Manger itself). From there it is redirected to LMDB.
Try transaction LMDB in Solution Manager. There you have (depending on your SP-Stack) access to several reports to evaluate your landscape.
Best regards, Alexander
