SAP BW 4/HANA connection issue: Object reference not set to an instance of an object.

[Anonymous]

Hello,

We try to connect to our new SAP BW 4/HANA database. We connect via Get Data -> SAP BW Application Server. 

We can connect but when we try to load a query we get the following message:

Any idea where to look for a solution?

Hi @Anonymous ,

SAP users need access to specific BAPI function modules to get metadata and retrieve data from SAP BW's InfoProviders. These include:

• BAPI_MDPROVIDER_GET_CATALOGS
• BAPI_MDPROVIDER_GET_CUBES
• BAPI_MDPROVIDER_GET_DIMENSIONS
• BAPI_MDPROVIDER_GET_HIERARCHYS
• BAPI_MDPROVIDER_GET_LEVELS
• BAPI_MDPROVIDER_GET_MEASURES
• BAPI_MDPROVIDER_GET_MEMBERS
• BAPI_MDPROVIDER_GET_VARIABLES
• BAPI_IOBJ_GETDETAIL

To solve this issue, verify that the user has access to the various MDPROVIDER modules as well as BAPI_IOBJ_GETDETAIL. To further troubleshoot this or similar issues, select Enable tracing on the Diagnostics window within Power BI Desktop's Options. Attempt to retrieve data from SAP BW while tracing is active, and examine the trace file for more detail.
