Please find the screenshot.
I have One extract for entire dashboard.
I have 2 ETL Jobs. One coming from Customer and 2nd one coming from Backorder,
customer ETL job gonna complete at 5AM IST and extract refresh gonna takes place. backorder job starts at 6AM.
After completion of customer etl job, i have refreshed tableau extract. I am able to see customer chart with updated data but unable to see Backorder chart.( Invisible).
Why my backorder chart is getting vanished when i try to refresh extract for customer??
What are you connecting to i.e. what are you creating extract of?
What ETL tool are you using?
Without clear understanding of your data movement it is very difficult to answer you question.
