Symptom
- 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."
Environment
SAP S/4HANA Cloud
Cause
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
Resolution
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:
- Go to "Extensibility Settings" app
- Click on the "Key User Extensibility" button to set it to "ON"
