Integrated at the BASIS/WAS layer, Firstlogic has developed Business Add-Ins (BAdI’s) that can be leveraged with a single instantiation; allowing for all SAP modules that utilize SAP’s Business Address Services framework to leverage the compelling advantages of Firstlogic technology. Furthermore, Firstlogic’s Information Quality Suite has been developed as a Remote Function Call (RFC) Server: the most common integration component of SAP software. Utilizing SAP’s RFC interface, SAP makes calls to Firstlogic technology for address check, updates, duplicate checks, and error-tolerant searches.
