How to change the data source of a model and run the existing queries?
I created a model based on excel file. after connecting to the data source (which is the his excel file) I created several steps and measures. Now I realized that it could be better to used a pivot table (which is in anotehr excel file) as a data source, instead of the first excel file. The layout is the same in both excel file and pivot table file (1st and 2nd file). When I change the data source to the pivot table excel file, it gives me error and I cannot connect it properly nor use the steps that I created beforehand. Error presented when trying to load new data source: "The key don't match any rows in the table". How to make that? Thanks, Diego
