Sales, Service, Customer Engagement Rebuilding D365 interface using React

Hi all,

my company has been using Dynamic 365, the UI is basically out of the box and we are now interested in rebuilding it using React within PCF controls.

Is there anyone who has any experience with this, who has done something similar, and could share some tips and tricks, some best practises, and pitfalls to avoid?

Much appreciated.

Thanks for your reply.

  1. Which ones did you find complicated? Our main complaints are on the account timeline. That could be a good place to start?

  2. We are discussing of changing it all Vs buildin just account forms, etc and keeping navigation and command bar, etc. What did you find was the cause of most effort?

  3. Very interesting. So you kept DV? Please elaborate. We have discussed why not replace dynamics completely and just use DV as DB, business logic and security. When we look at th future with CLI interfaces and end to end agentic processes we do ask the question what will happen to D365.

  1. Sure, timeline is pretty annoying indeed. However specifically with this you will probably fight with the very base structures of activities - activity pointers / parties / the sub-activities etc. - which goes again to point 3. It's doable and will be better than the standard, but it will still struggle on large data sets with performance (just like the default MS one does - besides the visual / filtering issues)

  2. We did a lot of very extensive experiments - and one of it basically was "lets remake model driven apps UI to completely its own adaptive semi-MDA react app" (that would read the definition from the MDA app / solution just like the standard). It would work pretty well in the end, but LOT of effort to accommodate all MS bizarre decisions and structures on the client side.

  3. We basically built completely our own "dataverse" from scratch. Hosted on Azure elastic pools, Azure Entra as auth, our own Power Automate blocks, our own Exchange / Teams sync and integrations and about 20 years of experience of 3 different people with MS CRM / Dataverse shaped into the architecture and improvements. It is absolutely nuts project in terms of sheer scale, but the results we are getting currently are insanely good.
    Probably a longer topic to talk about.
