Hi Rahul,

 

Thanks for the response.  I am able to access the data files in manage data catalog with no issue.  I am logged in to the cdf-fundamentals project as well.  My data sets are named Bernard1977 as seen below:

When navigating to the charts section, I am having issues.  Please see screenshots below. 

First it shows as if its trying to load like this:

 

And I ultimately receive this after trying to reload;

Any help will be greatly appreciated.  This is the final module prior to certification.

Thanks

Hi Bbauri,

Thanks for providing the console snap short of browser.
I have investigate deeply and found out all is working fine with the fusion. In the console , you have problem with failed to load resource:net::ERR_CERT_AUTHORITY_INVALID, which is related to your network connection and SSL certificate.

I recommend you to check your network connection and SSL certificate in your browser.

Hi @Eniko Farkas, I did, my network was too restrictive when I tried. And once I did I wanted to remove the comment, since I saw there were similar comments as well, which I’ve managed to miss somehow when I first went through the discussion 😅 Thanks for asking

Hello

I cant find the raw data for IFSDB data set i.e. where is the data for the maintenance events or the timeseries? I only loaded assets.csv file and that was for asset hierarchy. 

Thanks

Hello,

For the Data points step “Transform RAW to Data points” I received the error “Query returned no results. The query is syntactically correct, but returned 0 rows of data.” 

It seems the query does not filter for dataSetId and returns no matches. I changed the query to solve the issue on my end, here are the changes: 

SELECT
  concat('FirstnameBirthyear:',dp.sensor) AS externalId,
  cast(time_stamp/1000 as timestamp) AS timestamp,
  cast(value AS double)
FROM IFSDB.values AS dp
JOIN _cdf.timeseries AS ts 
ON CONCAT('FirstnameBirthyear:', dp.sensor) = ts.externalId
AND ts.dataSetId = '1234567890'

Hi @Aleksander Poverud 

Did you try to run it without the data set part? Since datapoints is such a big amount of data it is not always ideal to ‘preview’ datapoints. But for the preview part, your additional line of code is doing the trick!
