Keep historical data in Report Server
Hello, I currently face an issue : I have different Excel's files as source. For each of them, I have almost 7 million lines (client level, a line per month). I need to historise them in PBI Desktop because I'm on importation. Do you have an idea how to do that ? Thank you by advance, I hope there's no other message about this subject, I tried to find an answer but I didn't find one. Kind regards,
