Dataflow Error on save (dynamic data source)

Hey Everyone,

 

I have been using Dataflows for an API intergration for the last 2 months. Since the full release of the service i can no longer save a change. The M Function is the same but now i get this error,

 

"Your dataflow can't be saved because one or more entities references a dynamic data source"

 

Can anyone help?

 

Thanks

 

Darren.

Same issue for me

Hi, 

 

The solution in this post worked for me: https://community.powerbi.com/t5/Service/Dataflow-use-of-M-function-turns-workspace-into-Premium-cap...

 

It seems that putting the variables in a RelativePath argument avoids the dynamic data source error.

Hi, thanks for the hint.

unfortunately i am also not able to save the data flow cause due to the dynamic data set message when I try to save a function. It is a dedicated instance with the diamon. Any help highly appreciated.

 

let
Function1 = (inptFilePath, worksheet, startDate, endDate) =>
let
Source = Excel.Workbook(Web.Contents(inptFilePath), null, true),
#"sheet" = Source{[Item = worksheet, Kind = "Sheet"]}[Data],
 
in
#"Expanded dimPolicyStatus"
in
Function1
