• What is the cause and solution for SAP error message MDG_DT_DATA_MODEL116 - Invalid name used in structure; names must start with Z ?

  The SAP error message MDG_DT_DATA_MODEL116 indicates that there is an issue with the naming convention of a structure in the Data Model of SAP Master Data Governance (MDG). Specifically, the error states that the name used in the structure is invalid because it does not start with the letter "Z". In SAP, custom objects (like structures, tables, etc.) are typically required to start with "Z" or "Y" to distinguish them from standard SAP objects.
  Cause:
  
  Invalid Naming Convention: The structure name does not start with "Z" or "Y", which is a requirement in SAP to avoid conflicts with standard SAP objects.
  Configuration Error: There may be a misconfiguration in the data model or the structure definition that leads to the use of an invalid name.
  
  Solution:
  
  
  Rename the Structure: Change the name of the structure to start with "Z" or "Y". This can be done in the ABAP Dictionary (transaction SE11) or wherever the structure is defined.
  
  For example, if the structure is named MY_STRUCTURE, rename it to Z_MY_STRUCTURE.
  
  
  
  Check Data Model Configuration: Review the data model configuration in the MDG application to ensure that all custom structures adhere to the naming conventions.
  
  Navigate to the relevant configuration settings in the MDG application and verify the names of all structures used.
  
  
  
  Transport Requests: If the structure is part of a transport request, ensure that the transport is correctly configured and that the naming conventions are followed in all environments (development, quality, production).
  
  
  Testing: After making the changes, test the data model to ensure that the error is resolved and that the structure is functioning as expected.
  
  
  Related Information:
  
  SAP Naming Conventions: Familiarize yourself with SAP's naming conventions for custom objects. This is crucial for avoiding similar issues in the future.
  MDG Documentation: Refer to the official SAP MDG documentation for guidelines on data modeling and structure definitions.
  ABAP Dictionary: Use transaction SE11 to manage and create structures, tables, and other database objects in SAP.
  
  By following these steps, you should be able to resolve the MDG_DT_DATA_MODEL116 error and ensure compliance with SAP's naming conventions.
