3248190 - Items of type XXX must not be edited in this tenant | 3-System Landscape


  • You are trying to use a Key User Extensibility app
  • You are using a 3-System Landscape  
  • You are getting the error message "Items of type XXX must not be edited in this tenant." or "Extensibility is not active. Use the customizing tenant instead."




You're trying to use a Development Tenant to use the Key User Extensibility. 

As you're using a 3-System Landscape, you have two tenants in your Development System:

  • Customizing Tenant: Used for Business Configuration and Key User Extensibility.
  • Development Tenant: Used for Developer Extensibility


Use the Customizing Tenant. If the "Add"/"New" button is greyed out in your Customizing Tenant, it means that you still need to activate the extensibility in this system. To activate the extensibility, please follow the steps below:

  1. Go to "Extensibility Settings" app
  2. Click on the "Key User Extensibility" button to set it to "ON"
