How to do a double For/While?
I have a table with the following information:
| Index | Iteration | Points |
| 1 | 38 | 19 |
| 2 | 39 | 16 |
| 3 | 40 | 13 |
| 4 | 41 | 15 |
| 5 | 42 | 16 |
| 6 | 43 | 16 |
I need a double while/for to create the average of the last 3 iterations to a new table: (Example)
| Index | Iteration | Average |
| 1 | 40 | = (19+16+13) / 3 |
| 2 | 41 | = (16+13+15) / 3 |
| 3 | 42 | = (13+15+16) / 3 |
| 4 | 43 | = (15+16+16) / 3 |
I think recursion is not possible in Dax Code but I've tried different things to see a workaround.
Please help
Hi Anonymous,
If you would like to achieve the desired result with a DAX formula, you may try this Measure.
Avg = VAR avg_ = CALCULATE ( AVERAGE ( 'Table'[Points] ), FILTER ( ALL ( 'Table' ), 'Table'[Iteration] >= MAX ( 'Table'[Iteration] ) && 'Table'[Iteration] < ( MAX ( 'Table'[Iteration] ) + 3 ) ) ) VAR maxIndex = CALCULATE ( MAX ( 'Table'[Index] ), ALL ( 'Table' ) ) RETURN IF ( MAX ( 'Table'[Index] ) > maxIndex - 2, BLANK (), avg_ )Then, the result looks like this.

A new column
Var _sum = sumx(filter(Table, [Index]>= earlier([Index]) && [Index]<= earlier([Index]) +2) , [Points] )
Var _cnt = countx(filter(Table, [Index]>= earlier([Index]) && [Index]<= earlier([Index]) +2) , [Points] )
return
divide(_sum,_cnt)
If needed you can check for _cnt > 2
