Dear all,
I have the below table:
| Sales Person | Date Joined | Date Resigned |
| ABC1 | 01-Jan-15 | 27-Jan-16 |
| ABC2 | 01-Feb-15 | |
| ABC3 | 01-Mar-15 | |
| ABC4 | 01-Apr-15 | 23-Sep-15 |
| ABC5 | 01-May-15 | |
| ABC6 | 01-Jun-15 | 23-Sep-15 |
| ABC7 | 01-Jul-15 | |
| ABC8 | 01-Aug-15 | |
| ABC9 | 01-Sep-15 | |
| ABC10 | 01-Oct-15 |
How do I write the formula (measure) so that I can calculate my agency force as at every date?
Thank you,
Eric
