How do I delete items from feeder table without deleting from master in PQ editor?
Hello all, I am developing a report that will refresh monthly from a csv file. Each month a new csv with the previous months data will feed into this. Therefore, the mechanism is to load the data...
Power BI reads the data and nothing else. It doesn't store a historical copy. Any change to your data will reflect in the next refresh. If you removed some rows, those rows would be removed from the semantic model as well. If you want to keep all the rows, either the source has it or connect to a folder connecting csv files of the monthly data.
