Releasing Namespaces 

You assign objects in the ABAP Workbench to a namespace by adding the reserved namespace ID as a prefix to the object name. To make sure that a namespace can be used exclusively by its owner, the namespace ID can only be used as a prefix in the object name if the namespace is maintained in the namespace table in the SAP system, and has a valid development license. External systems (for example, customer systems of the SAP partner to whom the namespace belongs) into which objects with a prefix were imported, only allow changes to namespace objects if a repair license was entered. This is a repair license that the namespace owner has received from SAP and can pass on to customers, if necessary.
