How to create display column for multi-select choice?

Anonymous — Fri, 01 Apr 2022 04:17:08 GMT

Using CDS as data source to create Power BI graphs. In the data tables, there is a display column that can show the value of the choice ID selected for single-select choice columns in each row. It is created from the data source. For example,

fieldname	fieldname_display
0	A
1	B
2	C
3	D
4	E

How can it be created for multi-select choices?

Such as,

fieldname(multi)	fieldname(multi)_display
0,1	A,B
1,2,3	B,C,D
3,4	D,E
0	A,B
2,3	C,D

It will only display the left column, to show the choice IDs selected, with a comma to separate the values. How can it be done but to show the values of the choice IDs?

Hi @Anonymous ,

You can create a measure as below to get it, please find the details in the attachment.

FieldName_Display(Multi) = CONCATENATEX ( FILTER ( 'Table', 'Table'[fieldname] IN ALLSELECTED ( 'Table'[fieldname] ) ), 'Table'[fieldname_display], "," )

Best Regards

Hi @Anonymous , thanks for this solution. However my data table does not have the _display column to begin with, do you know how to create this multi choice _display column in the table?

Hi @Anonymous when we import the data columns from CDS to Power BI, it does not import the _display column. How do we create it?
