Help with automating append in power query

How can I setup a dynamic append between query1 and query2 so that query2 updates automatically with query1's refresh?
Note that query2 is a reference of query1 that has been filtered. And the data appended to query2 is query1.

I know query2' initial filtered data before the append will update because it is a reference of query1. But will the appended data also continuously update each time a new data is added and quey1 is refreshed?


Goal is to do a comparison in pivot table of original data "query1" and filtered data "query2". Both have have duplicate data so it's not possible to do one to many. I can do a bridge table, but that would mean adding a additional query for each field I want to use in the pivotTable..


The only reason I am creating a reference is because I don't want to pull twice from the source which is the case if I were to create query2 as duplicate instead..

Hi @StrPod ,


You're not avoiding a second pull from the source by referencing Query1.

There are some edge cases where Power Query can/will cache query results to use them later but you should generally assume a source hit per query, regardless of whether they are duplicated/referenced etc.

Hi @StrPod 


For the question "But will the appended data also continuously update each time a new data is added and quey1 is refreshed?", the answer is Yes. 


In every refresh, all queries will be refreshed. Since query2 is a reference of query1, you will find its data updated after a refresh completes.
