AccessOne is an information security software specifically developed for SAP™ Business Warehouse (SAP-BW). AccessOne allows you to build your access-control security in an easy excel-like matrix, and deploy it with a few clicks. BI AccessOne can extract access information from your ECC system (be it role-based, structural authorizations, etc), or a traditional SoD ACL matrix, or even an excel file you created on your desktop.
With AccessOne, you can assign any report to any role, without having to worry about access control and data security. Unless the user has specific authorization defined either in the transactional system or by means of any other specification, the user will not be able to pull any data outside of their own span of control.
