Result table keep to cumulative.

[u4us1923]

Hello Everyone ..

I have a lot of csv files (almost 50) to create my weekly report. I have imported these csv files in power query. These csv files are not readable, I edit them in Power Query. At the end of the day, I have a weekly result table from these csvs. But I want to keep the table cumulatively every week. I don't want to manually keep track of the keep every week. Can I do any process automatically.

Thnak you

Power BI has no memory* . You need to manage your snapshots/CSV file storage in the upstream system. * Yes, there is the self referencing option but that has no safety net.
