Hi dear community,
I work to set a reporting weekly refreshed. The problem is I made my reporting with a huge exctraction (30 columns, 50mb), and for performance reasons we decided to now use a little version of the extraction (around 20 columns). I removed all non -essential columns in my Power Query, but after changing the source to my new reduced CSV, Power BI keeps asking me for deleted colums, despite the fact i dont need them anymore.
Is someone has a solution for my problem ?
(Sorry for my very basic english)
