Extensions for D365 CE v 9.0
Contains basic execution context methods for extending Client-side functionality. In addition contains workflow and action caller.
To count or retrieve more than 5k records (50k for counting) we need to use a some kind of workaround. Using paging cookies we can control the page number count and use it for retrievement of more than 50k records.
In D365 v9.0 there is no way to set or change FetchXml directly from JS or via customizations, but it is possible to set a filter! This way is based on WebAPI ID retrievment -- > setting filter by ID on a subgrid.
