Dataflow Timeout

I am trying to create a dataflow with only partial values from a table. Is there a way to break the 1-year data into 4 months each and create 4 different dataflows using advanced editor. When I created a dataflow with entire 1-year data (Millions of records), it is taking more than 6 hrs to load that data in Power BI Desktop.

when you have connected to the 4 dataflows in Power BI Desktop like below (I added 2 as an example):

You can join the queries back together with Append Queries:

Hi @neetu14

In the editor of the dataflow using a date/datetime column you can use relative filters.

So you can choose Quarter 1 for dataflow 1, Quarter 2 for dataflow 2, etc.

Thank you. it worked 🙂

 

How do I connect these 4 dataflows together to get the complete data in 1 table in desktop like the original SQL table?

Table is empty after connecting the dataflow 😞

 

I have tried refreshing dataflow, refreshing the navigation pane in PowerBI desktop and clearing permissions as well but nothing is working.Dataflow.JPGPBIDesktop.JPG
