With July 2017 Update in Dynamics 365, Advanced Find view now supports Does Not Contain Data filter for related record.
So basically, we can now write a query like “Find all the lead records which doesn’t contain any related task”. However, we cannot define any filter conditions for the related record though.
The other interesting thing that we observed that in the case of N – N relationships it throws exception.
For e.g. if we want to find all the contacts that are not associated to marketing list
We get the following exception à
The does not contain data filter isn’t available while defining marketing list members in marketing list.
Hope it helps..
