Concatenate field in PBI

I have data looking like this:

Ticket   Tech
233450 qmi3
233450 top3t3
233716 hql8qoh
233893 wqd
234081 app3on
234179 momqt3
234179 hqw


I would like to create a DAX field that concatenates the Tech field so the data looks like this:

Ticket   Tech
233450 qmi3,top3t3
233716 hql8qoh
233893 wqd
234081 app3on
234179 momqt3,hqw

All help is much apprecated!


Well, this can be done in Power Query or DAX. Which is best depends on what you are wanting to do with it. In DAX, you could write a measure like this. 



place the ticket column in a matrix on rows and the measure above in the values section

Matt, I'm using Direct Query and need to buils the field in DAX,
I tried thie formula you gave me and it just places a comma after the existing field.
I need to concatenate the data from other rows when the Ticket ID is the same.

You need to change my formula TableName and TableName[ColumnName] to match your model

Yes, I changed the formula to this: TechConcat = CONCATENATEX(Installs,Installs[TECH],",")
I get this error: 

Error Message:
ORA-01704: string literal too long. The exception was raised by the IDbCommand interface.


my guess is that this is the total row.  Try this


= IF(ISFILTERED(Installs[TECH]),CONCATENATEX(Installs,Installs[TECH],","))

Ticket and Tech are columns in my Oracle db.  The query returns 4500 rows with Ticket as the id field and a Tech is on each row.
