  Causes:
  
  Foreign Key Constraints: The table from which you are trying to delete records may have foreign key constraints that prevent deletion if there are dependent records in other tables.

  Consult Logs: Check the application logs (transaction SLG1) for more detailed error messages that can provide additional context on the failure.
