SLAW2 is intended to be used by a central hub to collect and collate the data from all your audited systems, i.e. use this in your Solution Manager system. If you have SolMan 7.1, that will be on a NW 7.02 basis, and with current support packs SLAW2 will be available. In your other systems, you still run USMM as usual.
Cheers,
