DMC_IU055 - Details

• The SAP error message DMC_IU055 indicates that the namespace for the creation of upgrade transports is exhausted. This typically occurs when the system has reached the limit of available transport requests in the specified namespace, which is often due to a large number of transport requests being created without proper management or cleanup.
  
  Cause:
  
  Exhausted Namespace: The specific namespace used for upgrade transports has reached its limit. Each namespace has a finite number of transport requests that can be created.
  Transport Request Management: If transport requests are not properly released or deleted after they are no longer needed, it can lead to exhaustion of the namespace.
  System Configuration: The system may be configured with a limited number of transport requests allowed in the namespace.
  
  
  Solution:
  
  
  Check Existing Transport Requests:
  
  Use transaction code SE01 or SE09 to review existing transport requests in the namespace. Identify any that can be released or deleted.
  
  
  
  Release or Delete Transport Requests:
  
  Release transport requests
