Dynamics 365 for Sales is an application created and managed by Microsoft that gives Sales departments capabilities to manage Leads and Opportunities, right through to Invoices. This post gives a basic introduction to the capabilities of Dynamics 365 for Sales.
So this post is out of pure frustration that this information seems to be really hard to find (for me anyway) for what seemed like a basic requirement. I wanted to load a Gallery of information in a Canvas App based on the status reason within the Common Data Service. This field is often used in model-driven apps, including Dynamics 365 so being able to filter on this is pretty necessary for companion Canvas based apps.
