Hey @Iamnvt ,

 

in Power Pivot you are able to use the CALENDAR function as is described here:

https://www.sqlbi.com/articles/generating-a-series-of-numbers-in-dax/

 

Here is the DAX statement from above now using the function CALENDAR:

 

output calendar = 

var _in = 'Table'[input]
var _inAsPath = SUBSTITUTE(_in , ", " , "|")
var _inPathLength = PATHLENGTH(_inAsPath)
var _T = DISTINCT(SELECTCOLUMNS(ADDCOLUMNS(SELECTCOLUMNS(CALENDAR(1 , _inPathLength), "_Value", INT(''[Date])), "@item", PATHITEM(_inAsPath , [_Value] , TEXT)) , "@@item", [@item]))
return
CONCATENATEX(_T ,  [@@item], ", ")

 

Regards,

Tom

Hey @Iamnvt ,

 

you can use this DAX to create a calculated column:

output = 
var _in = 'Table'[input]
var _inAsPath = SUBSTITUTE(_in , ", " , "|")
var _inPathLength = PATHLENGTH(_inAsPath)
var _T = CONCATENATEX(DISTINCT(SELECTCOLUMNS(ADDCOLUMNS(GENERATESERIES(1 , _inPathLength) , "@PathItem" , PATHITEM(_inAsPath , [Value] , TEXT)) , "@@pahItme" , [@PathItem])), [@@pahItme] , ", ")
return
_T 

This is how it looks like:

@TomMartens  thanks for the answer

 

DAX in Power Pivot doesn't have GENERATESERIES function. 

is there any other way around?
