How do i achieve the below calculated field based on points column?
Change start into a date. Sort start ascending. Use Running Total tool (Transform tool palette with points as your sum column)...
1. add a record id tool after text tool
2., sort it in descending order of record id field,
3. add running total tool to points
4. sort record id field in ascending order
Find attached the way of doing that.
Let me know if there is any issue and do not hesitate to mark this answer as solution if it helped.
