I have been harassing this forum with Views for the last month. So maybe the main issue is my google skills or Microsoft Docs navigation.
I have this page: https://docs.microsoft.com/en-us/dynamicsax-2012/developer/view-overview I know everything in it. It's for AX2012 (I have noted a few differences in D365.) I can't find a similar page for D365. (Try googling "View" or "View Overview" - it's a nightmare.) And the mentioned page is definitely an overview - I'm looking for something more in depth (no disrespect intended, it's a good article).
The question I wanted to ask (and then realised I've posted one too many): It seems to me that the FirstOnly parameter on the root datasource of a view is ignored. Is that correct? In that case, I have found a few such limitations/unresponsive-properties in the metadata node (in comparison to an AOT query). It's very frustrating if your new to View's. I mean I'm not really sure what I'm doing and then after 50 hours of struggling find out that the property I have been toggling doesn't do anything. Hence the reason for the post - any sort of related reading material will be much appreciated.
Thanks for reading
