Hi,
Could someone help me with a calculated column index.
I have the following data:
| Sort | Test | Value | Outcome |
| 1 | 1 | 1 | |
| 2 | 1 | 2 | |
| 3 | test | 0 | 2 |
| 4 | 1 | 3 | |
| 5 | 1 | 4 | |
| 6 | 1 | 5 | |
| 7 | 1 | 6 | |
| 8 | 1 | 7 | |
| 9 | test | 0 | 7 |
| 10 | test | 0 | 7 |
| 11 | test | 0 | 7 |
| 12 | 1 | 8 | |
| 13 | 1 | 9 | |
| 14 | test | 0 | 9 |
| 15 | 1 | 10 | |
| 16 | test | 0 | 10 |
| 17 | test | 0 | 10 |
| 18 | 1 | 11 | |
| 19 | test | 0 | 11 |
Index needs to start with 1, if the column on the left is empty then I need +1 for the index column. I have tried the following:
Column = CALCULATE(SUM('Table'[Value]),FILTER('Table','Table'[Index]<=EARLIER('Table'[Index])))
But this was to heavy or something to calculate and it crashed.
How do I need to do this with a calculated column? Needs to be calculated column because the other columns are calculated as well.
Solved! Go to Solution.
Hi @TK12345 ,
As far as I know, there should be a column as a condition for calculated index column, such as [Date],[Value]... and so on. I couldn't find a column which could be condition in your above table. Is [Sort] column a calculated index column in your table and your calculation is heavy or something to calculate and it crashed? I think calculation is based on data model, here I suggest you to try to optmize your data model or your code and try again.
