Use calculated variable in web query with gateway

Hi

If use static web query link - gateway and report works well

(

   http://10.10.10.10/ERP-Orchids/hs/getting/20150101

)

But when I added calculated variable to link, PowerBI Desktop report works well, but I cant add gateway to report:

(

   v = Text.From( DateTime.LocalNow() )

   "http://10.10.10.10/ERP-Orchids/hs/getting/" & v

)

Is there way to use calculated variable in web query with gateway?
