Please see attached example files which has a PD column with about 43 unique ID for each years. Is there anyway I can separate this file into 43 data streams or 43 single data sets? then I can perform a series of calculations (same for each separated data set) on separated data sets.
For example one of separated data set would look like this:
| Year | PD | Amount |
| 01-31-2018 | 13 | 144720.4 |
| 11-30-2017 | 13 | 284440.3 |
| 12-31-2017 | 13 | 235645.1 |
