DataSource.Error: exceeded 100000 distinct who/what's

Hi, I'm getting this issue as well and also can't reach the links above. Anyone knows what to do?

Hi, for me it worked to get Admin profile in Salesforce and the error dissapeared.

Hi, was this issue ever solved? As a workaround, SF data can be pulled through external connectors, I've used this option for a while and I've never had this kind of issue. 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. 

Hi RichCopenhagen,

That "exceeded 100000 distinct who/what's" error is a Salesforce governor limit specific to Task and Event objects - both have polymorphic WhoId/WhatId fields, and Salesforce blocks the query when those references exceed 100K distinct values. Admin permission doesn't help here - it's an API limit, not a security one. The fix is to apply a filter before the query hits Salesforce - via Salesforce.Data Advanced Option → Select Query with hand-written SOQL (e.g. WHERE LastModifiedDate >= LAST_N_DAYS:30).

If you'd rather not write SOQL by hand, Power BI Connector for Salesforce on AppExchange handles filtering through a UI inside Salesforce:

Why it might fit:

• Filter conditions set on the Salesforce side - no SOQL hand-writing, no 100K distinct error
• No 2,000-row limit on reports
• Supports custom fields, custom objects, and joined reports
• 30-day free trial
• Setup docs: https://metricasoftware.com/docs/salesforce/
• Responsive support if you get stuck: https://metricasoftware.com/docs/salesforce/contact-support/

Happy to set up a quick demo on the Task object specifically. Just reach out via the support link.

Cheers,

Metrica Team.

For those still wondering, the Salesforce.Data built-in connector in Power Query folds queries, so you can include a filter in your query, which allows you to at least see what columns etc. are available. You can refine the filter after.

Here is what worked for me: 

let

Source = Salesforce.Data(

"https://login.salesforce.com/",

[

ApiVersion = 48,

CreateNavigationProperties=true

]

), 

Table = Source{[Name="Task"]}[Data],

Filtered = Table.SelectRows(

Table,

each [CreatedDate] >= #datetime(2026, 6, 1, 0, 0, 0)

) 

in 

Filtered
