You can loop over only one field and use index for others to get appropriate data:

foreach ($_POST["Description"] as $index => $val )
{
    $Description = $_POST['Description'][$index];
    $Unit        = $_POST['Unit'][$index];
    $Quantity    = $_POST['Quantity'][$index];
    $Cost        = $_POST['Cost'][$index];

    $array = array($Description, $Unit, $Quantity, $Cost);

    $query = "
        INSERT INTO MRF_Request (Qty, Unit, Description, Cost) 
        VALUES ('$Quantity', '$Unit', '$Description', '$Cost')
    ";

    odbc_exec($conn, $query);
}

You should also think about sanitizing your $_POST data, to make the system secure and reliable.
