The PROC IMPORT step is running in your SAS Grid environment on a UNIX/Linux platform.  This session probably does not have access to the path where your MDB sits, and even if it did the SAS session would not be able to process this import of a Windows database directly.  Instead, it would require a PC Files Server specification and use of the DBMS=ACCESSCS option to trigger it.  I'm guessing that you don't have all of that set up, but if you do a SAS admin would need to tell you exactly what the PC File Server host and port specification should be. Another possibility to get the data into the session via EG -- you could try File->Open->From ODBC.  Then you could use the Microsoft Access ODBC driver to open the database file.  However, for this large table it might be slow -- it's not usually the method we recommend.
