• Key Concepts: 
  Tenant isolation is a feature of the ABAP Runtime Environment (BC-ABA) in SAP that allows multiple tenants to run on the same system without interfering with each other. Each tenant is isolated from the others, meaning that their data and processes are kept separate and secure. This ensures that each tenant can use the system without worrying about the data or processes of other tenants. 
  
  How to use it: 
  Tenant isolation is enabled by default in the ABAP Runtime Environment. To use it, simply create a tenant in the system and assign it a unique ID. This ID will be used to identify the tenant and ensure that its data and processes are kept separate from other tenants. Once the tenant is created, you can begin using it as normal. 
  
  Tips & Tricks: 
  When creating a tenant, make sure to assign it a unique ID that is easy to remember. This will make it easier to identify and manage the tenant in the future. Additionally, make sure to keep track of all tenants in the system so that you can easily manage them and ensure that they are properly isolated from each other.
