Hello,
I am working on a requirement to snapshot some data ona weekly basis for Power BI usage.
I tried a solution using Incremental load I have a query with the following logic:
Select ItemCategory, Quantity, GetDate() as SnapshotDate From MyTable |
And I then set incremental loading in my flow baed on the SnapshotDate
-Storing 10 years of data
-Refreshing only last day.
My understanding was that when refreshing this dataflow every few days, the previously extracted data would not be affected (as it is out of the date range, and data would be appended.
What am I missing there ? I could not find in-depths explaination on Incremental refresh that could explain this.
