CZ178 - Details

• The SAP error message CZ178 indicates that the table you are trying to create or modify is already defined as an SAP standard object. This typically occurs when you attempt to create a database table in the ABAP Dictionary (SE11) that has the same name as an existing SAP standard table.
  
  Cause:
  
  Name Conflict: The table name you are trying to use is already taken by an SAP standard table. SAP has a naming convention where standard objects usually start with specific prefixes (like "T", "Z", or "Y" for custom objects).
  Namespace Violation: If you are trying to create a custom table in a namespace that is reserved for SAP standard objects, you will encounter this error.
  
  
  Solution:
  
  Use a Different Name: The simplest solution is to choose a different name for your custom table. Ensure that the name starts with "Z" or "Y" to avoid conflicts with SAP standard objects.
