Rumors have been spreading about
no-code and low-code being the way forward in the world of
Microsoft Dynamics 365 Customer Engagement and the Common Data
Service. To my knowledge, this is the result of the marketing
surrounding Flow, which is promoted as one of the three pillars of
the Power Platform, the two others being PowerApps and Power BI.
In my eyes, the difference between Flow and the native CRM
workflow ("Workflow") we know today is the over 200
connectors that allow flows to work with a large variety of data.
When I see this, I see the same advertisement that my cable company
gives me with 500+ channels. I fear that I will only end up using a
small subset of the connectors in Flow. Nonetheless, this is also
the feature I admire the most with Flow. It is not trivial to
combine data from different products using code.
So, when do we use flows? When you try to meet a business
requirement, you must always consider what this requirement will
evolve into in two weeks, six months or a year from now. I have
only chosen a Workflow once or twice in my life, and that was to
send emails. Once you choose to implement a workflow, calculated
field or any other solution, it is hard to switch. Therefore, I
always pick the most powerful option, which ends up being code.
By placing your logic in code, you make your system more
maintainable. You open your solution to the powers of DevOps and
strongly-typed development. You will no longer be prone to errors
related to removing fields from forms or the removal of option set
values, just to name a few.
Flows are declarative, which means they operate on a
higher-level than code. This also means they are less expressive.
If I had to convert the codebases of over 50,000 lines of plugin
code to flows, then it would be unmaintainable. My mind takes me
back to the horrors of giant Excel sheets that businesses used to
rely upon for their core business.
