I have never used FoxPro DBF. But by doing little bit of google found that there are JDBC-ODBC driver available for the same.
So, we can conclude that we can read the FoxPro dbf using JDBC-ODBC connection in ODI. So we can transfor an load data using SQL to SQL Knowledge modules.
Hope it helps!
If you need POC for the same then mai lme a sample DBF on mmy mail id email@example.com. I will try reading from ODI.
