• What is the cause and solution for SAP error message DHBAS_UTIL026 - Namespace of function group &1 is not /1DH/ ?

  The SAP error message DHBAS_UTIL026 indicates that there is an issue with the namespace of a function group in the SAP system. Specifically, the error message states that the namespace of the function group is not /1DH/, which is typically a reserved namespace for SAP's own development objects.
  Cause:
  
  Incorrect Namespace: The function group being referenced is not in the expected namespace. This can happen if a custom function group is created in a different namespace or if there is a misconfiguration in the system.
  Development Environment Issues: If you are working in a development environment, the function group may have been created or modified incorrectly.
  Transport Issues: If the function group was transported from one system to another (e.g., from development to quality assurance), it may not have been properly configured in the target system.
  
  Solution:
  
  
  Check Function Group Namespace:
  
  Go to the ABAP Workbench (transaction SE80).
  Locate the function group in question and check its namespace.
  Ensure that it is correctly defined under the /1DH/ namespace if that is the requirement.
  
  
  
  Create or Modify Function Group:
  
  If the function group is incorrectly named or in the wrong namespace, you may need to create a new function group in the correct namespace or modify the existing one to comply with the required namespace.
  
  
  
  Transport Configuration:
  
  If the issue arose after a transport, check the transport logs to ensure that the function group was transported correctly.
  If necessary, re-transport the function group or manually adjust it in the target system.
  
  
  
  Consult Documentation:
  
  Review any relevant SAP documentation or notes related to the specific function group or namespace requirements.
