Look up multiple values from one cell

[Charlie1234]

Hi,

I have a column in one of my data sources that holds staff ID numbers, but I need it to show as the staff members name.

I've used a lookup value against another table, but the trouble I am having is that it's not returning all the names because there are multiple staff ID's per cell in each line of data in the table as it was a "Table" but I extracted the values.

The dax/new column I have used is:

DAX:Project Team Staff Names = COMBINEVALUES(" ",LOOKUPVALUE('User Information List (2)'[FirstName], 'User Information List (2)'[Id], 'Project Highlight'[ProjectTeam(StaffInvolved_Id]),LOOKUPVALUE('User Information List (2)'[LastName], 'User Information List (2)'[Id], 'Project Highlight'[ProjectTeam(StaffInvolved_Id]))"

...which will only return data with a single ID.

I'll provide tan example below so you can see what I mean - the cell with multiple values won't return names. Ideally I'd like it to return all the IDs as names in that new column.

Any help would be great - apologies, I am not well versed in PBi as I only use it occasionally.

Project Team (Staff Involved ID)	Project Team Staff Names (as per dax above)
643	"Person A First Name" "Person A Last Name"
99, 26, 41, 579, 43, 181, 78, 145, 124, 173, 1033, 28, 27, 766, 300, 643
336	"Person B First Name" "Person B Last Name"

Hi , @Charlie1234 

According to your description, you want to lookup value from one table by ids , and in a row , you have multiple ids.

For your need , here are the steps you can refer to :
(1)This is my test data:

(2)We can click "New Column" and enter this:

Column = VAR Items1 = SUBSTITUTE ( [IDs], ",", "|" )
VAR T1 = GENERATESERIES ( 1, COALESCE ( PATHLENGTH ( Items1 ), 1 ), 1 )
VAR T2 = SELECTCOLUMNS ( T1, "@Item", PATHITEM ( Items1, [Value] ) )
var T3 = ADDCOLUMNS(T2, "name" , LOOKUPVALUE('Name'[FirstName],'Name'[ID],VALUE([@Item])) & LOOKUPVALUE('Name'[LastName],'Name'[ID],VALUE([@Item])))
return
CONCATENATEX(T3, [name] , ",")

Then wen can get this:

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!
