Nope, the SAP HANA database server always needs to get the information from the client.
So the question is: why does the ODBC client seem to "forget" your connection details.
As I have exactly zero (0) clue about FoxPro, I recommend enabling ODBC tracing to see, what information are actually passed to the ODBC driver.
Whenever I used ODBC for SAP HANA and stored the logon data I had not been asked for the information again.
