• What is the cause and solution for SAP error message MDG_DT_DATA_MODEL096 - Object names must start with Z* or Y* in development client ?

  The SAP error message MDG_DT_DATA_MODEL096 indicates that you are trying to create or modify an object in the development client that does not adhere to the naming conventions required by SAP. Specifically, in SAP development environments, custom objects (like data models, tables, or other development artifacts) must start with the letters "Z" or "Y" to distinguish them from standard SAP objects.
  Cause:
  The error occurs when:
  
  You attempt to create or modify an object (such as a data model, table, or structure) in the development client that does not start with "Z" or "Y".
  This is a safeguard to prevent conflicts with standard SAP objects and to ensure that custom developments are easily identifiable.
  
  Solution:
  To resolve this error, you should:
  
  Rename the Object: If you are creating a new object, ensure that its name starts with "Z" or "Y". For example, if you are trying to create a data model named CUSTOM_MODEL, rename it to Z_CUSTOM_MODEL or Y_CUSTOM_MODEL.
  Check Existing Objects: If you are modifying an existing object, verify its name. If it does not start with "Z" or "Y", you will need to create a new object with the correct naming convention and migrate any necessary data or configurations.
  Review Naming Conventions: Familiarize yourself with the naming conventions in your SAP environment to avoid similar issues in the future.
