MC204 - Details

• The SAP error message MC204 ("Table & already exists. Choose another name") typically occurs when you are trying to create a new table in the SAP system, but a table with the same name already exists in the database. This can happen in various contexts, such as when creating database tables in the Data Dictionary (SE11) or when working with custom development.
  
  Cause:
  
  Duplicate Table Name: The most common cause is that the table name you are trying to use is already taken by another table in the database.
  Namespace Conflicts: If you are working in a development environment, there may be naming conventions or reserved namespaces that are already in use.
  Transport Issues: If you are importing transport requests, there may be conflicts with existing objects in the target system.
  
  
  Solution:
  
  Choose a Different Name: The simplest solution is to select a different name for your new table that does not conflict with existing tables.
