• What is the cause and solution for SAP error message DMC_GENERAL335 - Name must start with Z, Y, or another customer namespace ?

  The SAP error message DMC_GENERAL335 indicates that the name of an object (such as a table, function module, or other development object) does not conform to the naming conventions required for customer-specific objects in SAP. Specifically, it states that the name must start with "Z", "Y", or another customer namespace.
  Cause:
  
  Naming Convention Violation: In SAP, customer-specific objects must start with "Z" or "Y" to differentiate them from standard SAP objects. This is a part of SAP's naming convention to avoid conflicts between custom developments and standard SAP objects.
  Incorrect Namespace: If you are trying to create or modify an object and the name does not start with the required prefix, SAP will throw this error.
  
  Solution:
  
  Rename the Object: Change the name of the object you are trying to create or modify to start with "Z" or "Y". For example, if you are trying to create a table named MY_TABLE, rename it to Z_MY_TABLE or Y_MY_TABLE.
  Check Namespace Settings: If you are working in a development environment, ensure that you are using the correct namespace settings. You can check the namespace settings in the SAP system by navigating to transaction SE03 (Transport Organizer Tools) and reviewing the namespaces.
  Use the Correct Development Package: Ensure that the object is being created in a development package that is assigned to the correct namespace. If you are using a package that is not customer-specific, you may need to create a new package or use an existing one that is designated for custom developments.
  
  Related Information:
  
  SAP Namespaces: SAP uses namespaces to organize and manage objects. Standard SAP objects are typically in the global namespace, while customer-specific objects are in the customer namespace (starting with "Z" or "Y").
  Development Guidelines: Follow SAP's development guidelines and best practices when creating custom objects to ensure compliance with naming conventions and avoid potential conflicts.
  Transport Management: If you are working with transport requests, ensure that the objects are correctly included in the transport and that the transport is released properly.
  
  By adhering to these guidelines and making the necessary changes, you should be able to resolve the DMC_GENERAL335 error and successfully create or modify your SAP objects.
