    Hi Taher,

     

    If you want it in DAX, you could try these two options.

    Option 1: there will be duplicate rows.

     

    New =
CALCULATE (
    CONCATENATEX ( 'Table1', 'Table1'[TagId], "-" ),
    FILTER ( 'Table1', 'Table1'[StoreId] = EARLIER ( Table1[StoreId] ) )
)

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

    Option 2: create a new table.

     

    Table =
SUMMARIZE (
    'Table1',
    'Table1'[StoreId],
    "NewColumn", CONCATENATEX ( 'Table1', 'Table1'[TagId], "-" )
)

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

    Best Regards!

If you want to concatenate them in 1 column, I'd suggest the following approach:

 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSAeJYHQjLCM4yBrOMgCwTOMsUzjJTio0FAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [StoreID = _t, TagID = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"StoreID", Int64.Type}, {"TagID", type text}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"StoreID"}, {{"Concatenate", each Text.Combine(_[TagID], "-"), type table}})
in
    #"Grouped Rows"

You group on StoreID, select the TagID column as list and combine all those items (Text.Combine).
