DAX: FILTER and CONCATENATE UNIQUE values

[Anonymous]

I am trying to FILTER/LOOKUPVALUE and CONCATENATE the relevant UNIQUE values but right now, I am unable to get it to work. I can only do it without the values being UNIQUE.

My current DAX formula:

CONCATENATEX (

FILTER (

ALL ( Table2 ),

Table2[Column1] = Table1[Column1]

),

Table2[Column2],

", "

)

The output from here goes like:
Value1, Value2, Value2

My desired output is: (without any of the values being duplicated)
Value1, Value2

@Anonymous  provide sample data and expected output to accelerate response

@Anonymous , try like

CONCATENATEX (
summarize(FILTER (
ALL ( Table2 ),
Table2[Column1] = cvShipments[Column1]
),
Table2[Column2]),
", "
)

@amitchandak Hi there, thanks for commenting. I tried but the output that I've obtained is "," and ", ,"

Seems like only commas are being concatenated here...

@Anonymous , Assuming this is a new column, I tried the same on my data, a new column. without all

Column = CONCATENATEX(summarize(FILTER(Sales,Sales[Item ID] = 'Item'[Item Id]), Sales[City Id]),[City Id], ",")

@amitchandak This works great, thanks. Think in the first comment you provided, there was a missing Table2[Column2] as part of the CONCATENATEX formula, hence the error.
