Before you begin with this Blog, please read my previous blog which was on How to Create Object Detection Model inside the Power Platform — PowerApps | AI Builder. In a previous blog, we have created the Object Detection Model that we are going to use in this blog. Step 1: Expand the AI Builder section in Power App and click on the Models. Open Fruit Detection Model that we have created in the Previous blog series. Click on the Use model and select the Create new App. It will redirect to the Power App Builder Studio. Step 2: You will see the Object Detector Control will automatically on the screen. Your application is ready you can run the detect the objects. Step 3: Now, we will insert the Gallery Control so that we can see the count of each object present in the images. Click on Insert and Select on the Add gallery. If you are not able to see the Option Expand the ribbon from Top right Side. Select Vertical and choose Title and Subtitle. Step 4: Click on the Gallery Control and set the property to ObjectDetector1.VisionObjects Click on the Title and set the property to ThisItem.displayName Click on the SubTitle and set the property to ThisItem.count We will do some changes in the font and alignment of the control so that the application should look simple, readable & accessible. Step 5: Click on File and Save the PowerApp. You can give the name and icon to your PowerApp. Your App is ready you can select your app and click on the Play. And Click Detect it will open your file explorer to select the images. If you are using this application on the mobile your camera will be open. Following is a screenshot of Application with detected Object Inside it. I hope this helps you to understand how to create an Object Detection models and use that Model in Power Apps.

In this blog, we are going to see how to create object detection model which can be used in PowerApps or MS Flow / PowerAutomate Step 1: Log in to portal.office.com. Select the PowerApps, If PowerApps is not visible then click on All Apps then you will able to see the PowerApps. Step 2: Expand the AI Builder Section and click on Build Section in PowerApps. Note: Please ensure that you are select the correct instance. Step 3: Click on the Object Detection Model We are going to create the Object Detection Model which can be used to created PowerApps or In MS Flow / Automate. Step 4: Name the AI Model and click on Create. Step 5: We will select the Domain of Model so we will go with Common Object. And click on Next. Step 6: Before moving forward, we will download the data which will be used to train and test the Model. Kaggle is the best source for the data to train the machine learning model. We will require the fruit images as we are designing the Fruit Detection Model, search fruit images and download the Dataset given in the screenshot. Select the Fruit Image for Object Detection Click on the Download Step 7: After downloading the Zip file extract it. You will see the following two folders — train_zip and test_zip respectively. Now, we will open the train_zip folder and you can see that there will be four categories of images Apple Banana Orange Mixed [Apple, Banana, Orange] Step 8: Let move back to the PowerApps Platform, 2nd step in the creation of Object Model is to define the object that we are going to detect. Here, we have three objects — Apple, Banana & Orange and click on next to move further steps. Step 9: We will require a minimum 15 images of each category to train our Object Detection Model. Now, we will click on Add Images and select Upload from local storage. Step 10: Select the images. Once all images are upload click on Close. Click on Next Step 11: Now, we are in the most important phase of the training where we provide the Tag or Label to the Images which we have uploaded. Click on the uploaded image and select the area where the object is present. Once you will select the area you will get the option to select the object is that present in the selection area. If an image is not suitable for the model to remove that particular image click on the “Don’t use Image ”. Click on remove to remove the image from the model data set. Step 12: Once you are done will the tagging or labeling the image click on the Done tagging. Note: Please ensure that you have a more tagged image for each model so that your model will work accurately. The more the label data more the accurate your machine learning model. Step 13: Click on the Train to start the training your model based on tagged images. Click on Go to Model It will take around 5–10 min to train based on your complexity of images, model and objects. Step 14: Publish the model. Once you model finished with done and you have published the Model. You can use that model to in Power App or MS Flow. We are going to see that in the next part of this blog.

Introduction: In this blog, I have introduced how to fetch a custom table from Microsoft Dynamics 365 Business Central into Microsoft PowerApps using Common Data Service(CDS) and OData. The table that was created in Business Central was fetched into a custom entity(MatchingLists) in CDS that allows me to create a local database in PowerApps for storing the entity data and OData that helps to fetch and integrate the data. Pre-requisites: Microsoft Dynamics 365 Business Central Microsoft PowerApps Steps: 1. Create a custom entity within Common Data Service(CDS) whose data you want to retrieve from Business Central. 2. Add the fields with their required data types. 3. Get Data from Business Central using OData Integration. 4. Go to web services in Business Central, add the custom page in the web services and use its OData V4 URL.  5.Enter the OData URL and the Organization credentials. 6. You will be shown the list of tables in each and every company. 7. Go to the table whose data you want to get into PowerApps, and select that table. 8. Next is to select the entity to be mapped with this table and field by field mapping of the same. 9. Refresh can be set manual or automatically, if automatic then select the time. 10. Create a list structure to dsiplay the table.

Introduction: This blog explains how to Filter records in gallery control based on value selected in other gallery control in PowerApps. Scenario: I am using Dynamics 365 Connection. I have data source named as Time Entry within that data source I have fields named as  Projects  and  Project task and data type of both fields is lookup. Values in Project Task is filtered based on value selected in Project field. Implementation Steps for Filtering Project Task based on Project: We must add Projects and Project Task data source in PowerApps because their data type is Lookup.(If you don’t know how to work with lookup fields Refer: https://www.cloudfronts.com/connect-dynamics-365-use-lookup-field-dynamics-crm-powerapps/ ) Add New screen name it Project Lookup and add gallery control on that screen. Select gallery control and set its item property to:SortByColumns(Search(Filter(Projects,statecode=0 ), TextSearchBox1_1.Text, “cf_name”), “cf_name” ) Add new Screen and name it Project Task Lookup and add gallery control on that screen. Select gallery control and set its item property to:SortByColumns(Search(Filter(‘Project Tasks’,     _cf_project_value =Gallery1.Selected.cf_projectid),TextSearchBox1_2.Text,”cf_name”),”cf_name”)here: Gallery1 is the name of gallery control on Project Lookup screen.

Introduction: This blog explains how to Integrate PowerApps with Dynamics 365. Keep the following restrictions in mind: Only PowerApps users in the same tenant can access the embedded app. To access PowerApps using Internet Explorer 11, you must turn off Compatibility View. Steps to be followed: In powerapps.com, on the Apps tab, click or tap the ellipsis ( . . . ), then Details. Copy the App ID. Substitute the [App ID]value in the URI.: https://web.powerapps.com/webplayer/iframeapp?hideNavBar=true&source=iframe&appId=/providers/Microsoft.PowerApps/apps/579938ff-e1a0-4891-a8b9-8d69c103fd84 Embed your app in a website: Embedding your app is now as simple as adding the iframe to the HTML code for your site.http://<iframe width=”[W]” height=”[H]” src=”https://web.powerapps.com/webplayer/iframeapp?hideNavBar=true& source=website&screenColor=rgba(165,34,55,1)&appId=/providers/Microsoft.PowerApps/apps/[AppID]”/> To add PowerApp inside CRM  as web resource: Keep the following points in mind for authenticating users of your app: If your website uses Azure Active Directory (AAD) based authentication, no additional sign-in is required. If your website uses any other sign-in mechanism or is not authenticated, your users see a sign-in prompt on the iframe. After they sign-in, they will be able to run the app as long as the author of the app has shared it with them Steps: Specify the width and height for App. Specify the app id. Sample HTML code: <!DOCTYPE html> <html>  <head> <title>HTML Iframes</title> </head> <body> <p>App Goes here…</p> <iframe width=”250″ height=”250″ src=”https://web.powerapps.com/webplayer/iframeapp?hideNavBar=true&source=website&screenColor=rgba(165,34,55,1)&appId=/providers/Microsoft.PowerApps/apps/579938ff-e1a0-4891-a8b9-8d69c103fd84″ /> </body> </html>
