Query from large set of data, old data doesn't have to be updated

Hi all,

 

I have a large set of data with stock movements. As I refresh my document, there is no reason for all the data to be downloaded for new as old stock movements haven't changed. 

 

What would be the best way to speed up the process and prevent old data to be refreshed for no reason?

 

(I am thinking of dividing my query into two pieces by dates and setting the old data to be excluded from refresh..)

 

Any ideas highly appreciated!

 

Jenny

That's a good plan, to the best of my knowledge Power BI does not currently support incremental refresh. You could create 2 queries that get the same data but for different date ranges and set one of them not to refresh. Then perhaps an Append query to combine them together into a single table. In theory, at some point in the future, create a third query, set the second query to not refresh, add to Append query, etc.
