Copy Table in Power Query Without Data Source

Hello,

 

I'm trying to expedite my refresh time for a large report with lots of tables. There are 3 or 4 which are causing most of the issues which I'm trying to tackle.

 

In Power Query I want to copy a table (T1), and carry out subsequent applied steps to produce another table (T2), however I just want to copy T1, I do not want T2 to refresh from the source in SQL on my scheduled refreshes, as this file takes a long time to refresh.

 

I can find documentation online which explains Copy/Paste, Duplicate and reference but all of these then go to the source in SQL when I run a data refresh, is there any way to avoid this so T1 refreshes and T2 just takes the latest data from T1.

 

It's worth mentioning producing the new table in SQL is much slower than what can be achieved in power query, and I also know I can create a DAX table, however I am unpivoting 150+ columns which is not really practical.

 

If anyone has any experience with the above scenario I would be extremely grateful.

 

Thanks

Unless you made it a table of records, but you can't use Dax on that.

No, you cannot dynamically stopped that source table from refreshing.
