Incremental refresh on Report with auto refresh Dataflow

[robotbi]

Hi, this may be a silly question..

I need to build a Bi report which shows cost trends from 2019 to yesterday, and table contains 300million rows, so I have to set up incremental refresh.

On Power Bi service: I splited the data into 2 sets: 1) 2019 - 2023 as archived and static;  2) 1/1/2014 - yesterday as dynamic, and I loaded them into 2 dataflows, and set the 2014 dataflow with auto refresh schedule on every morning.

On Power Bi desktop: I loaded the two dataflows and appended the two queries to create this big report, and it takes more than an hour to refresh everyday. Right now, I am trying to set up Incremental Refresh on this report: Ive set it up with parameters and policy and published to Service. 

The goal is to let the report auto refresh every 6am, and have the 2019 - 2023 static data as well as 2014 incremental refreshed data. 

Is there a way to achieve this? Or do I need to hit the report refresh button everyday  after the dataflow finished auto refresh? Thanks much in advance for any advices!

Hi @robotbi ,

Below is my table:

Now you should create two parameters: RangeStart and RangeEnd

Here's a detailed incremental refresh strategy based on your rules:

After that, you can publish it to the service, and then you can set up a scheduled refresh every morning at 6:00 am to refresh.

Static data for 2019-2023 will remain unchanged, while data for 2014 will be progressively refreshed based on date parameters you define.
