Using Visual Composer from NWDS - CE as BI Data Source (BPM tables)

Hello

We´re using Visual Composer to build bpm analytics reports. Acessing Visual  Composer from browser (/VC) works perfectly, we can see tables from CE, on BI Data Source option.

But when using Visual Composer directly on Developer Studio. On select provider, when I click on BI Data Sources, there´s an error message:

"Check the BW systems. Check the BW configuration in the System Landscape. Make sure the user mapping is set correctly and all connection properties are correct".

But I´m not trying to connect to any BW system, I want to view CE Bpm tables.

Thanks!
