• What is the cause and solution for SAP error message ESH_CU_SEM030 - ID has to start with Y or Z ?

  The SAP error message ESH_CU_SEM030 indicates that a certain ID (usually a custom object or a custom namespace) must start with the letters "Y" or "Z". This is a common convention in SAP systems where custom developments are required to use these prefixes to differentiate them from standard SAP objects.
  Cause:
  
  Naming Convention: In SAP, standard objects (like programs, function modules, classes, etc.) typically do not start with "Y" or "Z". Custom objects must follow this naming convention to avoid conflicts with standard SAP objects.
  Configuration or Development: The error may occur during the creation or modification of a custom object where the ID provided does not adhere to this naming rule.
  
  Solution:
  
  Change the ID: Modify the ID of the object you are trying to create or modify so that it starts with either "Y" or "Z". For example, if you are trying to create a custom program with the ID ABC123, change it to YABC123 or ZABC123.
  Check Configuration: If you are working with a configuration or development tool, ensure that the settings or templates you are using are set up to generate IDs that comply with this naming convention.
  Review Documentation: If you are unsure about the naming conventions or the specific requirements for the object you are working with, refer to the SAP documentation or guidelines provided by your organization.
  
  Related Information:
  
  SAP Namespace: The use of "Y" and "Z" is part of SAP's namespace management, which helps in organizing and managing custom developments.
  Transport Requests: When transporting custom objects between systems (e.g., from development to production), ensure that the IDs remain compliant with the naming conventions.
  Best Practices: Always follow best practices for naming conventions in SAP to avoid issues with object identification and to maintain clarity in your development environment.
  
  If you continue to encounter issues after making these changes, consider consulting with your SAP Basis or development team for further assistance.
