If there are no joins required and they are truly two separate data sources, then....
1) Close your second connection in your screenshot.
2) Click on Data > New Data Source
In the superstore workbook, there are three data sources. None of them have to join to the other, but do based on blending on correct fields. If you don't need to join/blend your sources, then my steps above will work and your end result will look similar to the screenshot, only with 2 sources.
Great I will tray and let you know thanks
