Calling a function and function name is in a data row

Hello everyone,

 

I would like to add a new column using pre-made functions with 2 parameters, and the name of functions are in a column.

 

I used Expression.Evaluate + Record.Combine to accomplish so previously.  However, as #shared only works in Power Query but does not work in Power BI, I need other solutions.

 

Could someone please help me with the correct M expression?

 

Thank you so much for your time and help.

Just found others' solution.

 

First, turn the functions that I need into a list then use that list.

 

var_Shared = #shared,
ProcessorFunctionNames = List.Select(Record.FieldNames(var_Shared),each Text.EndsWith(_,"Processor")),
Result = List.Transform(ProcessorFunctionNames, each _ & " = " & _ & ","),

 

Original expression:

Expression.Evaluate( _[Processor] & "( _[Folder Path] & _[Name] , _[Publisher] )", Record.Combine({[_=_],#shared}))

 

New expression:

Expression.Evaluate( _[Processor] & "( _[Folder Path] & _[Name] , _[Publisher] )", Record.Combine({[_=_],Result}))

 

However, I am getting an expression error "Cannot turn values of List type into Record type.

Could anyone please help me with this line?  Thank you very much.
