HOW CAN I USE MY HOLOLENS WITH DYNAMICS 365?
I recently did a video and released it on a Friday night. No one saw it, but I still think it’s interesting, so I figured I’d document how it worked. Long story short, I wanted to try to create Microsoft Dynamics 365 for Field Service work orders with a Microsoft HoloLens. There’s no native app at this point, so I needed to put together a work around. I created a Power App, logged into the Power App via Edge on the HoloLens, and then updated Dynamics 365 with Flow. Here’s how.
THE POWER APPAs you can see in the above screenshot, the Power App is pretty straightforward. I just created a blank app, added some labels and branding, and then created a few controls. Of particular interest is the data sources for these controls. The data bound to the drop down is a Dynamics 365 connection. I have multiple connections to handle the accounts, the field service work order type, and the field service incident type. Ultimately, the data point selected by the user are going to act as inputs to a Flow, so I needed to have enough information to create the field service work order. The other interesting part is the code behind the Submit button. This logic takes the inputs from the user, based on their selections and entries into the Power App, and submits them to a Flow. After the submission happens, the user is sent to a thank you screen and the experience ends.
When a user hits the submit button on the Power App, Power Apps submits the selected information to the Flow using a “PowerApps” trigger. These inputs are handled both in a “Create a new record” Common Data Service action and creating a file in SharePoint to record the images.This solution uses Microsoft Power Automate to perform the record updates based on the input from the Power App. Additionally, this flow handles the input from the HoloLens’s camera as a string, passes it through an Azure Function App (thanks to this wonderful blog post from John Liu) and converts it to bytes. One little HoloLens-specific trick here – the device’s camera saves the files as PNG, so the Azure Function has to say body = body.Replace(“data:image/png;base64,”, “”) instead of body = body.Replace(“data:image/jpeg;base64,”, “”).
Finally, one of the benefits of using the HoloLens is the camera. I created a SharePoint document folder to hold the images that are sent with the Flow. By making sure the filename matches the Field Service work order ID, it’s easy to see which photos relate to which order.
THE FINISHED PRODUCT
Here’s the finished video. I used the record feature on the HoloLens to record what I was seeing and then edited the videos to better show what was on my screens. For some reason, the monitors showed up mostly white, but the images should help visualize.
