Newb here to PowerBi and DAX.
I have multiple files in very similar formats for different fiscal years:
| Year | OrgID | Value1 | Value2 |
| 20152016 | 001001 | 2 | 26 |
| 20152016 | 001002 | 58 | 6378 |
| Year | OrgID | Value1 | Value2 |
| 20142015 | 001001 | 3 | 25 |
| 20142015 | 001003 | 59 | 6399 |
The data comes via Excel, and I have four years of these files. Each file is formatted similarly (but not necessarily exactly), and the Year field is formatted as text like above. There is no guarantee that an Organization will be there from one year to the next. Plus, I have a corresponding Profile data file for each organization for each year. I want to allow the user to slice the data by year and organization, and probably other fields as well.
Should I flatten all the data into one table, and all the profiles into its own table, or one big table, or keep them all separate? If separate, how do I do this?
Thanks for any assistance.
