Smart SAP Assistant

• What is the cause and solution for SAP error message MDG_DT_DATA_MODEL147 - Object names must not start with Z* or Y* in delivery client ?

  The SAP error message MDG_DT_DATA_MODEL147 indicates that you are trying to create or modify a data model in SAP Master Data Governance (MDG) using object names that start with "Z" or "Y". In SAP, object names that begin with these letters are typically reserved for customer-specific developments, and the system enforces this restriction to maintain consistency and avoid conflicts with standard SAP objects.
  Cause:
  The error occurs when:
  
  You attempt to create a new data model, data element, or any other object in the delivery client (client 000) using names that start with "Z" or "Y".
  The naming convention is violated, as SAP restricts the use of these prefixes in the delivery client to ensure that standard objects remain intact and unaltered.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Rename the Object: Change the name of the object you are trying to create or modify to ensure it does not start with "Z" or "Y". Use standard naming conventions that are allowed by SAP.
  
  
  Use a Different Client: If you are working in a development client (not the delivery client), you can create objects with names starting with "Z" or "Y". However, ensure that you follow the proper transport and development guidelines to move these objects to production.
  
  
  Check Naming Conventions: Familiarize yourself with SAP's naming conventions and guidelines for object names to avoid similar issues in the future.
  
  
  Consult Documentation: Refer to SAP documentation or the SAP Help Portal for more information on naming conventions and restrictions related to your specific version of SAP MDG.
  
  
  Related Information:
  
  SAP Naming Conventions: SAP has specific guidelines for naming various objects (like tables, data elements, domains, etc.). It's important to adhere to these conventions to avoid conflicts and ensure compatibility with standard SAP functionality.
  Development Client vs. Delivery Client: Understand the difference between development clients (where custom developments are made) and delivery clients (where standard SAP objects are maintained). Custom developments should typically be done in a development client and transported to the delivery client as needed.
  SAP Notes and Community: Check SAP Notes for any updates or specific guidance related to this error message. The SAP Community forums can also be a valuable resource for troubleshooting and finding solutions shared by other users.
  
  By following these steps and guidelines, you should be able to resolve the MDG_DT_DATA_MODEL147 error and proceed with your development work in SAP MDG.
