Requirement
We need to limit how many records a Dynamics 365 (D365) view returns. Since there’s no out-of-box (OOB) way to do this, we introduced a custom column dsl_topn. This column holds the “Top N” value we want. A plugin then intercepts the FetchXML query and injects the <fetch top="N"/>
attribute, removing any conflicting paging attributes in the process.
