Invoke function inside a list?

Hi 

 

I would like to create a list of numbers but the number of rows will depend on a function that calls and API and returns the number of rows  I have tried.

 

= List.Numbers(0,Function.Invoke( fnDealsIterations()),100)


the function has no variables and just returns a number 4 at the moment, 

is this possible?

 

thanks

Hi  @jasemilly ,

 

Create a function as below:

 

 

let
    Source =()=>let
       Source= 4
     in 
       Source
  
in
    Source

 

 

Then create  a query as  below:

 

 

let
    Source = List.Numbers(0,#"Invoked Function",100)
in
    Source

 

 

And you will see:

Hi @jasemilly 

As long as the function retunr the data type required as second argument of List.Numbers it should certainly be possible. Have you tried it?  I do not think you need the Function.Invoke
