Function within power query

Hi All!

 

This is my 1st post.

 

So...I've this query (it works well):

let
Source = Sql.Database("Server123", "abc"),
dbo_xyz = Source{[Schema="dbo",Item="xyz"]}[Data],
#"Accepted equals 0" = Table.SelectRows(dbo_xyz, each [Accepted] = 0),
#"Changed date/time to date" = Table.TransformColumnTypes(#"Accepted equals 0",{{"StartDay", type date}}),
#"StartDate before today" = Table.SelectRows(#"Changed date/time to date", each [StartDay] < DateTime.Date(DateTime.LocalNow()))
in
#"StartDate before today"

 

What I want to do is instead of putting "DateTime.Date(DateTime.LocalNow()))" is to put my function Today, which is pretty much the same code:

() =>
let
Source = DateTime.Date(DateTime.LocalNow())
in
Source

 

I try to learn something, but when I do something like:

#"StartDate before today" = Table.SelectRows(#"Changed date/time to date", each [StartDay] < Today)

 

I gain an error power bi cannot compare function with date...I get it, I need somehow to force m query to return result of Today instead of comparing Today, but I don't know how...I tried as well Function.Invoke but it needs 2 parameters (function and arguments, in my case it's very simple function with no args). Is it even possible? Is my fucntion missing something?

Re: Function within power query

Normally you have to call the function with (), so Today().

 

To test this function, you should add a column using Today(). That way you can prove that the function works before using it in a comparison
