2486898 - "New" button is greyed out in Custom Communication Scenarios app - SAP S/4HANA Cloud Public Edition

"New" button is greyed out in Custom Communication Scenarios app as shown below:

SAP S/4HANA Cloud Public Edition

There are three possible causes for this issue:

1. The Key User Extensibility is not activated in the system.
2. The system doesn't support Key User Extensibility (for example the Productive System).
3. "Unrestricted" authorization is not maintained in the Business Role that provides access to this application. The Business Role is Read Only restricted with "Write Access: No Access".

1. Activate the Key User Extensibility in Extensibility Settings app.
2. Use a system that supports Key User Extensibility.
3. Review the Business Role which is used to grant access to the application. Change the restriction to "Write Access: Unrestricted" or create a new Business Role unrestricted and assign to the user.
