Published report from different sources doesn't work

[Anonymous]

I have a report with 3 different sources:

1. Excel file

2. PBI Calendar table

3. Tables from the DWH (SQL DB)

The report works at desktop, but when i pulish it and open from the service, i get the error:

"This data source cannot be accsessed by a data gateway..."

I've tryed to publish both: my workspace and group workspace.

Any ideas?

Thanks
