I am a Power BI Desktop newbie. I am bringing data from Snowflake into Power Query in Import mode, and then adding various transform steps (replace values, add columns, etc.). Every time I make a change to a step, Power Query refreshes and re-Imports the data from Snowflake again. It takes forever to make a small number of changes, because I have to wait for the refresh from Snowflake every time. I just want it to import the data once, and then edit the remainder of the query.
I saw options for adjusting how often data refreshes, but that just seems to turn off Power Query previews.
Any suggestions?
It is a good practice to uncheck the "Allow background refresh" option, but another is to add a Keep Rows step early in your query to limit the # of rows while you are building. Once all your transformations look good, you can delete that step and load all the data.
