Hi,
I have build few OData based PBIX files. All of the refresh fine in Power BI desktop but when refresh is schedued from PBI-RS (March 2018 Update), One of them fails with following error. Only difference between the one which refresh fine and the one which does not is that it has little larger sized datasets. However they all refresh fine in Power BI Desktop without any issue.
When refresh failes, following error is logged in RSPowerBI_2018_*****.log file

On few occasions, I have noticed that my scheduled refresh from PBI-RS succeed without any error. That makes me think that it has to be related to some timeout but logs are not verbose enough to point to a specific timeout setting. I have tried play around with following rsreportserver.config settings but none has helped
<Add Key="DatabaseQueryTimeout" Value="300" />
<Add Key="RunningRequestsScavengerCycle" Value="300" />
<Add Key="RunningRequestsDbCycle" Value="300" />
<Add Key="RunningRequestsAge" Value="300" />
I have also added following config entries in msmdsrv.ini but again no luck
<ExternalCommandTimeout>3600</ExternalCommandTimeout>
<ExternalConnectionTimeout>600</ExternalConnectionTimeout>
<ForceCommitTimeout>600000</ForceCommitTimeout>
Please let me know how can I get around this error.
Thanks...
