The ScrapeMap Data Preview Pane displays a sample of the data being scraped from the website. This lets you see sample write output for the DataAddresses while you are creating the ScrapeMap.
The Data Preview pane typically displays only DataAddresses in the Root InstructionSet on the first screen of data. The results of Actions may not appear in the Data Preview pane. In the screenshot below there is a BrowseTo Action to get a DetailedDescription DataAddress which has no data displayed in the Data Preview Pane. The actual write output will include all of the DataAddresses and Actions defined in the ScrapeMap.
