Hi,

I understand that initially data manipulation is applied on sample records(5000). The manipulation is carried on the entire dataset after processing the workbook.

In this regard is it possible that when I carry out an 'Inner join' on two sheets the result is a blank sheet because the random sample have no union?

how do I remedy this apart from increasing the sample size?

Thanks!

  Hi Enaven,

   

  Good question. 

   

  This was an issue in the past which was met with Datameer's Smart Sampling. This method better ensures that analysts will not experience a blank page like you are describing. 

   

  However, if you are experiencing a blank worksheet which you believe should show data, run or re-run your workbook and then check back on that join sheet to see the results. 

   

  Let us know if this works for you.

   

  Cheers,

  Rob

  Hi Rob,

  Thanks for the immediate reply. I went through the link you shared for smart sampling.

  According to the link,  The optimized preview(smart samples )can only be generated only when workbook is run. does this (run) mean processing of the workbook?

  Thanks!

  Yes, running the workbook means processing the workbook. It will regenerate the Smart Sample when it is run and the joined records would expect to get populated if there wasn't any in the original sample set.
