Hi Knimers,
I am trying to achieve the following.
| ID | SOURCE |
| AB | 0 |
| AB | 0 |
| AB | 1 |
| AB | 0 |
| AC | 0 |
| AC | 0 |
| AC | 1 |
For every ID (as a group), I would like to delete the 0 that come before the first 1?
I know I need to take a group loop, but afterwards which node I need to take to write a rule like "IF source before 1 -> Delete"
Many thanks.
