Thousands of functions and processes across multiple modules deployed via hundreds of complex roles and responsibilities can mean keeping control of license usage can be extremely difficult. You may have hundreds or thousands of user accounts with access to multiple roles and responsibilities; all of this means there could be literally millions of individual access points that need to be reviewed from a licensing perspective.
An added obstacle to understanding license usage is that a significant number functions (screens) within Oracle EBS are not mapped to a module out of the box (approx. 83% in EBS Release 12.2.7); this makes performing a detailed analysis extremely difficult if not impossible.
Reviewing your application license usage is not something you do once and forget about, it is an ongoing requirement that you should revisit periodically to ensure your license usage remains under control.
CS License greatly simplifies the review process by analyzing what your active users have access to in terms of the individual functions and processes to give you a detailed analysis of exactly who can do what. With this raw data, we can determine how many users you have that are likely to require licenses for a given module. This can help ensure that your license usage is closer to what it should be.
