Query Append fails when using enterprise gateway to SAP BW

Hello,

 

I have two queries that pull data from SAP BW via an enterprise data gateway. I then combine them into one table using TABLE.COMBINE() in M.

 

This works fine in the desktop, but when I publish to the service it fails every time. 

 

Is there a setting on the gateway that is preventing the combination of the data (much like in a DATAFLOW?)

 

Any ideas are much appreciated -- spent all day on this.

 

Jim

Hi @Anonymous ,

As mentioned in the "Planning a Power BI Enterprise Deployment" whitepaper:

"

There are limitations within the On-Premises Data Gateway that prevent certain types of complex M queries (used to load data into Power BI) from running successfully, even if these M queries succeed when the dataset is refreshed within Power BI Desktop. Scenarios where this happens include combining data from online and on-premises data sources, and using M functions to make multiple calls to web services.

"

Maybe you can try to use the personal gateway, the following two posts also discuss similar issues, you can see if it helps:

Team,

 

To reduce the black box effects, I pulled the data in separate queries and then combined them with a DAX - UNION statement.

 

Would have been nice to use M for all of it, but I had to get a solution in place.

 

Thanks,

 

Jim
