DAX How To Dynamically Concatenate Earlier Row Values
I would like to, using DAX because my table will be filtered dynamically and have different ModelNumbers each time, come up with a way to produce a concatenated list (comma deliminated) of all Val1 row values in scope.
| ModelNumber | Val1 | DYNAMIC COLUMN |
| 100-01 | 456 | 456 |
| 200-01 | 21 | 456, 21 |
| 300-02 | 18 | 456, 21, 18 |
| 400-01 | 5 | 456, 21, 18, 5 |
CURRENT FORMULA:
PreviousText = MINX(
FILTER('Table1',
'Table1'[modelNumber] = EARLIER('Table1'[modelNumber])),
'Table1'[Val1])
Current Result: Error Message: single value for modelNumber cannot be determined.

I just normalized the ModelNumber into a dimension table that is why you see it as another table

Not sure if you are after something like this?
=
IF (
HASONEVALUE ( 'Models'[ModelNumber] ),
CONCATENATEX (
FILTER (
ALLSELECTED ( 'Models'[ModelNumber] ),
'Models'[ModelNumber] <= SELECTEDVALUE ( 'Models'[ModelNumber] )
),
CALCULATE ( SUM ( Data[Val1] ) ),
", "
)
)Thanks for the fast response. Your example is exactly what I am looking to do. My results outputs are not the same as yours. The only difference I see is all my data is coming from the same table, and you have the values coming from the data table as an example. What am I doing wrong?
See Concatenation is not working like yours
