  The SAP error message UJ0_UT_EXCEPTION023 indicates that an import operation is being attempted on a table that is not empty. This typically occurs in the context of data transport or data import processes, such as when using the SAP Transport Management System (TMS) or during data uploads.
  Cause:
  The error arises when:
  
  You are trying to import data into a table that already contains records.
  The import process is designed to only allow empty tables to be populated to prevent data integrity issues or conflicts with existing data.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Table Contents:
  
  Verify the contents of the table you are trying to import data into. You can do this by executing a simple SELECT query in the database or using transaction codes like SE11 (Data Dictionary) or SE16 (Data Browser).
  
  
  
  Clear the Table:
  
  If it is appropriate to do so, you can clear the table before attempting the import. This can be done using a DELETE statement or through transaction codes that allow you to delete records. Be cautious with this approach, as it will remove all existing data in the table.
  
  
  
  Modify Import Settings:
  
  If you are using a specific tool or method for the import, check if there are settings that allow for appending data to non-empty tables. Some tools may have options to merge or update existing records instead of requiring an empty table.
  
  
  
  Consult Documentation:
  
  Review the documentation for the specific import process you are using. There may be guidelines or best practices for handling non-empty tables.
  
  
  
  Contact Support:
  
  If you are unsure about the implications of clearing the table or modifying the import process, consider reaching out to your SAP support team or consulting with an SAP expert.
  
  
  
  Related Information:
  
  Data Integrity: Always ensure that clearing a table or modifying data does not violate business rules or data integrity constraints.
  Backup: Before making any changes to the database, it is advisable to take a backup of the existing data to prevent accidental loss.
  Transport Management System (TMS): Familiarize yourself with the TMS if the error is occurring during a transport operation, as it has specific rules regarding data consistency and integrity.
  
  By following these steps, you should be able to resolve the error and successfully complete your import operation.
