• What is the cause and solution for SAP error message UJ0_EXCEPTION120 - Table &1 already exists ?

  The SAP error message UJ0_EXCEPTION120, which states "Table &1 already exists," typically occurs when there is an attempt to create a database table that already exists in the system. This can happen in various scenarios, such as during data loading, system upgrades, or when executing certain transactions that involve table creation.
  Cause:
  
  Table Already Exists: The most straightforward cause is that the table you are trying to create is already present in the database.
  Incorrect Configuration: There may be a misconfiguration in the system that leads to the attempt to create a table that should not be created again.
  Data Migration Issues: During data migration or system upgrades, scripts may attempt to recreate tables that have already been created in previous steps.
  Custom Development: Custom programs or enhancements may inadvertently try to create a table that already exists.
  
  Solution:
  
  Check Table Existence: Verify if the table indeed exists in the database. You can do this by using transaction codes like SE11 (Data Dictionary) or SE16 (Data Browser) to check for the table.
  Modify the Logic: If you are developing custom code, ensure that the logic checks for the existence of the table before attempting to create it. You can use SQL statements to check for the table's existence.
  Adjust Migration Scripts: If this error occurs during a migration or upgrade, review the scripts to ensure they are not trying to create tables that already exist. Modify the scripts to include checks for existing tables.
  Delete or Rename the Table: If the table is not needed, you can delete it (if it is safe to do so). Alternatively, if you need to keep the data, consider renaming the existing table before running the process that creates the new one.
  Consult Documentation: Check SAP notes or documentation related to the specific transaction or process you are executing to see if there are known issues or recommended solutions.
