Generateseries of multiple values

This topic was solved by simplifying the code in the earlier topic as follows:

Series = 
GENERATE(
    VALUES('Tasks'[Task]),  -- Iterate over distinct Task Names
    VAR MaxFinalLife = MAXX(FILTER('Tasks', 'Tasks'[Task] = EARLIER('Tasks'[Task])), 'Tasks'[Final Life])
    RETURN
    SELECTCOLUMNS(
        GENERATESERIES(1, MaxFinalLife, 1),
        "Series", [Value]
    )
)

Hi DataNinja777 ,

This formula refers to an existing table.

Series = 
VAR __TBL =
    SELECTCOLUMNS('Data', "Start Date", 'Data'[Start Date], "End Date", 'Data'[End Date], "Index", 'Data'[Index] )
VAR __MAX = MAX ( Data[Month] )
VAR __Series =
    GENERATESERIES ( 1, __MAX, 1 ) --must use the highest month count
VAR __CROSSJOINED =
    ADDCOLUMNS (
        CROSSJOIN ( __TBL, __Series ),
        "Date", EDATE ( [Start Date], [Value] ) - 1
    ) -- this will generate dates way later than the end date
RETURN
    FILTER ( __CROSSJOINED, [Date] <= [End Date] )

Index is not necessary. It is just a way for me to identify which row from the referenced table a row in the series table is referring to.  Be warned that doing this on a large table may cause a performance issue.
