BI Training with Salesforce Objects Expert?

Hi, were you able to find a solution? As a workaround, maybe you can try to test your connection with a 3rd party connector, which pulls data from the SF objects connector and lets you pre-filter your data in the tool UI before exporting it to PBI. That will let you load only needed fields and date range to Power BI and your report will load faster, which seems was a problem in your case. I've tried windsor.ai, supermetrics and funnel.io. I stayed with windsor because it is much cheaper so just to let you know other options. In case you wonder, to make the connection first search for the Salesforce connector in the data sources list:

After that, just grant access to your Salesforce account using your credentials, then on preview and destination page you will see a preview of your Salesforce fields:

There just select the fields you need. It is also compatible with custom fields and custom objects, so you'll be able to export them through windsor.  Finally, just select PBI as your data destination and finally just copy and paste the url on PBI --> Get Data --> Web --> Paste the url.
