Data Preview

In this article, we'll guide you through the process of improving preview performance times by filtering out unnecessary data.  This is particularly useful when dealing with large volumes of data.

Step 1: Initiate your preview by selecting the preview icon.

Step 2: Instead of processing all the data and then filtering out the unnecessary records, filter out the data before the preview data is returned by adding a preview filter.

Step 3: Configure your preview filter using the same syntax as the "Apply Filter by Expression" syntax.  In this example, we're removing records where the Gross_Weight is less than 33.

Step 4: Select Apply to save your Preview Filter.

Step 5: Run or refresh your preview.

Now, the preview only returns records with gross tons of less than thirty-three. This upfront removal of data early in the process significantly improves preview performance times.
