CONCATENATE DAX function not recognized in Custom Column Window
I'm trying to merge the contents of two columns (text) in Transform Data Table with a new Custom Column but Custom Column window doesn't recognize CONCATENATE function and the formula produces error.
How could I merge the contents and why some functions are not recognized?
Hi Anonymous ,
Microsoft Power BI supports two different languages, M language(in Power Query) and DAX .
CONCATENATE() function is used for DAX not for M.
So if you could use the following to get the same effect:
#"Grouped Rows" = Table.Group( #"Changed Type" , {"Cate"}, {{"Custom", each Text.Combine([Value], "/"), type text}})Table 2 = ADDCOLUMNS ( VALUES ( 'Table (2)'[Cate] ), "Product", CALCULATE ( CONCATENATEX ( VALUES ( 'Table (2)'[Value] ), 'Table (2)'[Value], "/ " ) ) )My final output looks like this:

Anonymous , Are you trying in power Query M. There you can Text.Combine , it need a list -https://docs.microsoft.com/en-us/powerquery-m/text-combine
Or try Like
New column = [col1] &" " &[col2]
In Dax you have concatenate

Could you tell me if your problem has been solved? If it is, kindly Accept it as the solution. More people will benefit from it. Or you are still confused about it, please provide me with more details about your table and your problem or share me with your pbix file from your Onedrive for Business.
