PowerApps and Flow: Level 2 - Building Business Solutions with PowerApps and Flow Course Outline

 (3 days)

Building Business Solutions with Power Apps and Flow is an intensive 3-day training class designed for people who have experience using PowerApps and Flow and are ready to move their skills to the next level. Students will learn best practices for building canvas apps and flows to update and manage content in Azure SQL, SharePoint Online, Excel workbooks and OneDrive for Business.

After providing a foundation for building canvas apps and flows, this course teaches students how to build business solutions with the Common Data Service for Apps (CDSA) by creating custom entities and model-driven apps. The class also examines advanced techniques required in real-word PowerApps scenarios such as creating custom connectors and conducting application lifecycle management (ALM) using managed solutions and multiple environments for development, UAT and production.

Student Prerequisites
Students should already be familiar with Microsoft Excel, Office 365 and SharePoint Online. Due to the accelerated nature of this training class, it is also recommended that students attend ONLC's Designing Modern Forms and Workflows with Microsoft PowerApps and Microsoft Flow training before taking this class or have the equivalent hands-on experience with PowerApps and Flow.

The module explains how data within a flow is propagated from step to step and discusses how to use control-of-flow actions to author advanced business logic. Students will learn the syntax for writing advanced expressions in Workflow Definition Language (WDL) to retrieve dynamic content, to perform type conversion and to design flows using loops, variables, arrays and custom objects.
Topics Covered
Building Flows using Triggers and Actions
Using Control-of-Flow Actions
Writing Advanced Flow Expressions
Executing a Flow from a Canvas App
Handling Flow Execution Errors

Module 05: Building Flows to Manage Content and Approvals
This modules focuses on using Microsoft Flow to update, manage and transform content in SharePoint Online and OneDrive for Business. The module demonstrates how to build a scheduled flow to enumerate the items in a SharePoint list to clean up and validate the data entered by business users. Students will learn build flows that upload documents and images to SharePoint Online and OneDrive for Business and to convert document content between common file formats such as JSON, XML, HTML and CSV. The module demonstrates building flows to automate the generation of Word documents and PDF files using the using the Word Online connector. This module examines the support in Microsoft Flow for automating an approval process using the Start an Approval action. Students will learn how to build flows to automate an approval process including document approval in SharePoint Online.
Topics Covered
Reading and Writing SharePoint List Content
Uploading Documents, Images and Photos
Using Flow to Generate Word and PDF Files
Using Flow to Automate Approval Processes
Managing Approvals using Approvals Center

Module 06: Getting Started with the Common Data Service
This module introduces the Common Data Service for Apps (CDSA) and explains how it provides a standardized database schema for business data used by PowerApps, Flow and Dynamics 365. Student will learn how to import external data into the CDSA and how to build canvas apps to read and write records for standard entities such as accounts, contacts and activities. The module teaches students how to customize standard entities as well as how to create custom entities to accommodate specific business scenarios.
