FIXED: Error: "Failed to read GatewayCore property: EnableFastCombine"

I was trying to refresh a report in the service that uses the Adobe Analytics connector and a on-prem database using the gateway, but kept getting this error:

 

Underlying error message: [Unable to combine data] <removed> references other queries or steps, so it may not directly access a data source. Please rebuild this data combination.

 

I have "Ignore the privacy levels" checked in my report settings, so I thought this was pretty strange.

 

I was also seeing this error in the on-prem data gateway logs:

 

Failed to read GatewayCore property: EnableFastCombine, Ex: Object reference not set to an instance of an object.

 

I found page, talking about adding something to the config file in the personal gateway:

https://docs.microsoft.com/en-us/power-bi/service-gateway-personal-mode#using-fast-combine-with-the-...

 

Even though it says this fix is for personal gateway, I thought I'd try it--and it fixed the issue.

 

 

I added the following to "Microsoft.PowerBI.DataMovement.Pipeline.GatewayCore.dll.config":

 

 

<setting name="EnableFastCombine" serializeAs="String">
    <value>true</value>
</setting>

And now my reports are refreshing.

FYI this work-around is no longer working for me with the July 2019 version of the Gateway.

FYI, this change gets removed from "Microsoft.PowerBI.DataMovement.Pipeline.GatewayCore.dll.config" when a new verison of the gateway is installed and has to be reapplied.
