Only load new data

Hello,

I am needing some assistance with a current issue. I am connected to MySQL and I have a dashboard that will update daily and include historical data. I have a table of historical daily data and a table of new day data. I want to only append the new data to the historical data without refreshing or loading the other table. I am not sure the the difference between enable load and report refresh.

How can I only run one table and turn off the other so that it no longer loads the same data again. Hope this makes sense.

Thank you for your help!
