When it comes to having a successful SAP licensing audit, remember the acronym “ECC”:
1. E - ELIMINATE inactive user accounts and also inspect the need for accounts with low-activity. After that, continue by identifying duplicate accounts and ELIMINATE them too.
2. C - Carefully COMBINE all user accounts of the same employee from multiple SAP systems to a single employee record. Since an employee can use multiple applications, this is a crucial step in achieving good SAP licensing.
3. C - CLASSIFY each employee according to the most appropriate license type. Don’t count on the current license type but re-inspect it carefully according to volume of activity, the type of activities done, etc.
