I have an issue that I will try and explain. I have three data flows of the same fact table that contain one for current year, prior year and 2 years ago. They all refresh and show the data correctly. I then created a linked data flow and brought those three different data flows in and then created a new append query and saved that as a new data flow. Data is showing for the append query.
I then tried to create a new link data flow so I can then apply transformations and grouping to it. When I am at the Get Data/Choose data window and I select the appended data flow, it doesn't show any records. Now I can select the original three data flows that are linked into that appended data flow and each one does show data even though the appended data flow doesn't show data but when you are in the appended data flow it does show data that it appended the three data flows. I have refreshed it but still not showing records.
The odd thing is that I have done this correctly with other data flows and shows data in the appended data flow. I have also recreated the original data flows and linked data flows in a different workspace but still get the same results. These are Gen 1 data flows using Premuim edition.
Any help would be appreciated.
