If you are trying to create a new table in MongoDB, you will need to utilize the  **GenerateSchemaFiles**  connection property and set that value **to OnCreate**. All you have to do is go to your connection manager, and under  **Advanced**  change the value of  **Generate Schema Files**  to  **OnCreate**.
