Concatenate a field within IF/SWITCH statement

[Anonymous]

Hello Everyone, 

I'm new to Power BI. I have created a new column in my report using this SWITCH statement to group Institutions based on the below conditions.  What I want is Concat "Control Group1" with INSTITUTIONS[NAME] within the SWITCH statement.  Tried Using CONCATENATE  and COMBINEVALUE functions as well as below method. All of those gives me " Error Message:
OLE DB or ODBC error: [Expression. Error] We couldn't fold the expression to the data source. Please try a simpler expression.." Error.  I'm using Direct Query mode in My Report.

Appreciate If anyone can suggest me a method to concat a string with Table[ColumnName] within a SWITCH Statement

INSTITUTIONS GROUP= SWITCH ( TRUE (),
INSTITUTIONS[ID] = "d3a2efa8" || INSTITUTIONS[ID] = "721be8893","Control Group1" & " - " & INSTITUTIONS[NAME],
INSTITUTIONS[ID]="729dbb5a-"
|| INSTITUTIONS[ID] ="b7ea8f29"
|| INSTITUTIONS[ID] ="6d85fa58"
|| INSTITUTIONS[ID] ="1df7d3ed","Control Group2","Control Group3")

Thanks

@Anonymous , You have to create a measure in that case

INSTITUTIONS GROUP= max(values(INSTITUTIONS) , SWITCH ( TRUE (),
INSTITUTIONS[ID] = "d3a2efa8" || INSTITUTIONS[ID] = "721be8893","Control Group1" & " - " & INSTITUTIONS[NAME],
INSTITUTIONS[ID]="729dbb5a-"
|| INSTITUTIONS[ID] ="b7ea8f29"
|| INSTITUTIONS[ID] ="6d85fa58"
|| INSTITUTIONS[ID] ="1df7d3ed","Control Group2","Control Group3") )
