In the past couple of weeks I’ve been using PowerApps, and the overall experience has been great! SharePoint Designer and InfoPath have been replaced by a browser based application that is a lot easier to work with. Of course it is still all very new but the general experience is very good.

Today, I will be looking at Flow. A Flow can be triggered by a lot of things , but for now I will look at a flow that is triggered by a PowerApp.

In the past I wrote Workflow articles about Nintex Workflow and how to setup the workflows. I have always liked the state machine workflows and I was wondering if I could setup my Flows in a similar way.

So If we start with the basics. Adding some tasks. Within Flow there are a lot of tasks available and for Flows related to PowerApps that use SQL Server as their data source I could imagine that there may be a lot of Update row actions in my flows. Flow supports both on-premises and Azure based SQL installations as the “Connect via on-premise (hic) data gateway” indicates.

For small flows it will be quite easy to just stick action after action. But once a few additional actions are added it might be useful to organize the no-code a bit.

Comments

As with Nintex, Microsoft has now introduced comments for each step

This makes the workflows already a lot easier to understand and compared to SharePoint Designer workflows this is already a massive improvement.

 

 

Renaming actions

Next to adding comments it might also help to rename all the actions within a flow. This helps documenting the Flow without the real need for additional documentation outside the Flow.

 

Variables

Within Flow it is possible to create variables. So I’m adding a Variables – Initialize variable action to my flow.

Within this action I’m creating a variable State Machine Status

Then I’m adding a Do Until Action

The Do Until action I’m configuring to run until my status variable has been set to Complete.

 

Then Inside my Do until I create a Switch, which can be found in the … More.

Then by clicking on the + between Case and Default  I add all the different states that I want to go through.

Then for each state I’m added a state change:

 

Time to add the real work into my Flows and my state machine workflow is ready.
