问题 I want to be able to perform a FetchXML request that sums a value while grouping on a field that is a custom option set but I don't get the expected results. All that is returned is the summed up values, not the related custom option set value that it relates to so I have no idea what the returned values relate to.

问题 I have an entity which has latitude and longitude fields. Now I have a address, I know the latitude and longitude of this address, I want to retrieve the records within 3 miles.

Fetch XML report aggregate undocumented limit

阅读更多关于 Fetch XML report aggregate undocumented limit

I've been struggling with this one fetchxml report for Dynamics CRM online. The report is using aggregate to detect duplications based on certain fields.

Is there any workaround for this (except to use normal fetchxml to get
