Edit SAP BW variables in PowerBI service

Hi all, 

i try to use the functionality of "allow report readers to change SAP variables for this report". As a data source we use SAP Business Warehoue. 

I went throw the documentation:

DirectQuery Connection - Yes 

Workspace - Yes - Premium per User

Single sign-on (SSO) - Yes

Latest GateWay - Yes

Option is selected - Yes

The filter links was not appearing so refreshed manually the report. 

Any hint to get the variables run?
