The DTS is a function within SQL Server where you can configure Data Transformation services.
So you can configure that a source file (accessed by ODBC or OLE DB if it not native SQL Server Data) is going to be imported into some table into some Database in a SQL Server.
You can even define some transformations on each fieldfs if you want. These transformatuion can be configured by the wizard or can be written in VBScript.

You can choose to create the table if it doesn´t exists.
You can also configure it to run automatically periodically.

To do the import from within VFP, you must know the fields types and lengths in order to execute the transact SQL command (via SQLEXEC) to create the table.
You can do it with 'Afields()'
