SAP BW (demo) and Microsoft PowerBI Desktop. Step by step guide

Prerequisites

You installed SAP NetWeaver AS ABAP Developer Edition
For example, you did it in the cloud with this Step-by-step guide
Explore your new developer SAP system you find that SAP_BW (SAP Business Warehouse) component installed, transaction RSA1 properly working and a lof of BI pre-delivered content exists in the system. For learning purpose your want use querying tool for existing demo InfoObjects (InfoCubes, DSO and so on)
For example, you want to use Microsoft PowerBI Desktop on your Windows machine for this purpose.

Resolution

As we see in this MS guide
Mandatory requirement for connection between MS PowerBI and SAP BW is installed SAP Net Connector
Quote:
“Implementation 2.0 of the SAP Connector requires the SAP .NET Connector 3.0. Access to the download requires a valid S-user. Contact your SAP Basis team to get the SAP .NET Connector 3.0” 
Lucky peoples with S-user can download SAP Connector from Support Portal – https://support.sap.com/en/product/connectors/msnet.html
Resolution for users who don’t have S-user account and who can’t download files from SAP Support Portal
If we consider installation media closer we can find Connector here –
<extracted path>\client\SAPGUI4Windows\BD_NW_7.0_Presentation_7.50_Comp._2_\PRES1\GUI\WINDOWS\Win32\System64\SAP .NET Connector\.NET40\ 
OK, In this point we must add this DLLs’ to GAC ( Global Assembly Cache )
An Easy way for lucky peoples who have Installed Microsoft Visual Studio:
cmd
gacutil -i <assembly name>
Resolution for users who don’t have Visual Studio IDE and who can’t use gacutil
If we consider PowerShell (this tool basically exists in each Windows machine by default) closer we can find related for our purpose functional:
[System.Reflection.Assembly]::Load(“System.EnterpriseServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a”)
$publish = New-Object System.EnterpriseServices.Internal.Publish
$publish.GacInstall(“<extracted path>\client\SAPGUI4Windows\BD_NW_7.0_Presentation_7.50_Comp._2_\PRES1\GUI\WINDOWS\Win32\System64\SAP .NET Connector\.NET40\sapnco_utils.dll”)
$publish.GacInstall(“<extracted path>\client\SAPGUI4Windows\BD_NW_7.0_Presentation_7.50_Comp._2_\PRES1\GUI\WINDOWS\Win32\System64\SAP .NET Connector\.NET40\sapnco.dll”)
$publish.GacInstall(“<extracted path>\client\SAPGUI4Windows\BD_NW_7.0_Presentation_7.50_Comp._2_\PRES1\GUI\WINDOWS\Win32\System64\SAP .NET Connector\.NET40\rscp4n.dll”)
$publish.GacInstall(“<extracted path>\client\SAPGUI4Windows\BD_NW_7.0_Presentation_7.50_Comp._2_\PRES1\GUI\WINDOWS\Win32\System64\SAP .NET Connector\.NET40\libicudecnumber.dll”)
Run Microsoft PowerBI and try to connect to your  SAP NetWeaver AS ABAP Developer Edition
Connection example:
After the connection is successfully established you can obtain data from BW
File – Get Data – SAP Business Warehouse Application Server
List of Objects available for querying
For example, InfoCube – 2CREPM_PRODUCT [1]
Everything works correctly
