Message no. TO133
Diagnosis
This SAP System does not have a valid development license for the namespace *ABCDEF*.
System Response
You cannot edit objects from namespace *ABCDEF* in this SAP System.
It is not possible to create the namespace *ABCDEF* with the namespace role P (producer) without specifying a valid development license.
Procedure
Have your system administrator check the change licenses of the namespace *ABCDEF* in your SAP System.
Maintain the namespaces with the Transport Organizer tools: Transaction SE03 -> Administration -> Display/change namespaces.
The following cases need to be distinguished:
• The namespace begins with “/0SAP”:
Make sure that the namespace role is “C” (recipient) and the “SSCR popup” and “SAP standard” indicators are activated. The license fields remain empty.
• You have not created the namespace yourself, but the owner of the namespace is SAP AG or another software manufacturer:
Make sure that the namespace role is “C” (recipient). The valid license must either be entered in the field Repair license, or the “SSCR popup” indicator must be activated. Contact the owner of the namespace, who can tell you what you need to do and what the valid repair license is.
• You yourself are the owner of the namespace:
In this case, follow the instructions in the documentation about applying for and setting up namespaces. The documentation describes how you can obtain the valid development and repair license.
