Hi, I have a set of data, where I would like to check a time sequence of the events for the subset (id).
For example,
for ID 1 I would like to check, that Event 71 happened before 72.
If the event didn't happen or in a wrong seq
| ID | Timestamp | Event 1 | Event 2 |
| 1 | 2020-01-01 10:00:00 | 71 | Send |
| 1 | 2020-01-01 10:01:00 | 72 | Receive |
| 1 | 2020-01-01 10:02:00 | 73 | Convert |
| 2 | 2020-01-01 10:00:00 | 71 | Send |
| 2 | 2020-01-01 10:01:00 | 73 | Convert |
