Trying to return comma separated values from filtered related records in a column

[Anonymous]

I am trying to find the right formula in DAX for this and getting nowhere.

I have two tables:

1. The first table is Projects, this has a ProjectID column, and many others.
2. The second table is Contacts related to projects, which also has a ProjectID column, which is used to relate contacts to projects many to one. There is also a Role column and a Name column on the Contact table.

I need to create a column on the Projects table which shows, in a comma separated list, the Names of all the contacts where 1) ProjectID on the Contact = ProjectID on the Project, and 2) the Role value for that row of the Contact table contains a certain string.

I have used CALCULATE successfully to do the same kind of thing, summing values on a related table with multiple filter criteria applied to which rows are included, but I'm failing on getting text values concatenated into a comma separated string in the same way.

I need something that works exactly like:

CALCULATE(SUM(column),
FILTER(criteria),
FILTER(criteria),
FILTER(criteria)
)

Except instead of SUM, it returns a text string with all the names that match the criteria. I've been playing with VALUES and CONCATENATEX, but I can't get the syntax to work.

@amitchandak That did it for a single filter criteria--thank you!

What's the best way to do it with multiple fitlers? I just nested a second FILTER within the first, and that seems to work. Is there a more elegant and easier to read method?

@Anonymous , Create a new column in project table

concatenatex(filter(Contract, contract[project id] = project[project id]),[contract id])

correct column name as per need
