Power Apps Tutorial for Beginners

In this Power Apps tutorial, we will start from the basics of Power Apps and learn all the major Power Apps concepts that a Power Apps professional must be aware of. Now, let’s have a look at the components of this tutorial.

What is Power Apps

Power Apps is a collection of programs, applications, services, and data platforms that enable rapid application development. With the help of Power Apps, we can build and personalize business apps quickly, without depending on the IT Professionals and Programmers. Applications developed through Power Apps provide abundant workflow and business logic abilities to make your manual business automated. Users can subscribe to Microsoft Power Apps in office 365, Dynamics 365, or as an independent product.

Need and Importance of Power Apps

Microsoft introduced Power Apps to overcome the following problems.

  • Lack of professional mobile app developers - Gartner forecasted that the demand for mobile app developers would increase at least five times more compared to the IT organization's ability to deliver. The reason for this situation is the deficiency of professional mobile app developers to meet the requirement.
  • Expansion of business data - Business data is expanded across various systems and exceeded the firewall and SaaS cloud. As data is stored in various systems, we cannot access the data from the app.
  • App sharing and IT Activities - Mobile apps are distributed through app stores and mobile devices. This established an inheritance methodology to get the app onto the mobile devicel Now

Microsoft Power Apps

With the help of Power Apps, we can build and personalize business apps quickly, without depending on the IT Professionals and Programmers. Users can subscribe to Microsoft Power Apps in office 365, Dynamics 365, or as an independent product.

Power Apps can be classified into three categories; they are:

  • The App itself
  • Connections to your data.
  • Flows: Workflows thrown by apps.

#1. The App itself

Through Power Apps, We can create any app for mobiles, tablets, or desktops. The developed apps perform some general functions based on the template. Customization of apps can turn into more specialized and specific. PowerApp studio can create and modify the layout the same as with the App. In addition to templates, we can also develop the apps from scratch to get more adaptability concerning the application’s flow.

#2. Connectors to the data

While creating an app through a template, Power Apps queries about data source that you want to use for your App, some of the accessible data sources are:

  • Salesforce
  • Dynamics 365
  • Sharepoint list

For instance, if we want to develop an app that performs some operations on the contacts of the client, then we have to develop the application on SharePoint.

Developing mobile applications through Power Apps will take only a few clicks. For customizing and prioritizing the data, we can use the drag and drop mechanism. After creating the App, you will have separate screens for browsing records and displaying the details of documents.

#3. Microsoft Flow

Microsoft flow is the primary engine running behind the apps you run. An app is defined as a collection of many automated processes or workflows. An app is created to do certain operations on the data. Flow teaches us how our apps should perform these operations. To run our app on our device, we should install a Power Apps app on our machine.

Microsoft Flow automates various repetitive tasks, which enables you to dedicate more time to essential tasks. In addition to automation, we can establish API connectors and gateways for traditional solutions through the sophisticated integration tools of Power Apps.

Microsoft Power Apps is useful in various industries like Manufacturing, Pharmaceuticals, Information Technology(IT) as it can automate any routine task.

Advantages of Microsoft Flow

Through Microsoft Flow, we can perform the following things easily.

  • Establishing the workflows to receive notifications and handling the work
  • Applying various connectors to interchange the data between SharePoint and other Microsoft or different third-party services.
  • Create items and custom APIs.
  • Using the SharePoint list, we can create CRM entities.
  • We can share the data between SharePoint and Dropbox, one drive, etc.
Working of Microsoft Flow

To create a workflow, Microsoft Flow provides various templates to create the workflow immediately. If we cannot find a suitable template for a specific task, we can create a template that meets our requirements.

Power Apps Functions

The main functions of Power Apps are as follows

#1. Power Apps Search Function:

Power Apps Search function is used to locate the records which contain the required string. The string can occur anywhere in the column.

The syntax of the search function is as follows: Search( Table, RequiredString, Column)

  • Table: This field refers to the table to be searched.
  • RequiredString: This field refers to the string to be searched.
  • Column: This field refers to the column within the table to be searched.

Example:

Emp_Name  Emp_ID Emp_Salary
Rajesh 01 25000
Mahesh  02 38000
Suresh 03 50000

 Now, we will apply the search function on the above employ table.

Search(Employ, “esh” . Emp_Name)

The above search function returns the records which have the “esh” string in the Emp_Name Column.

Emp_Name Emp_ID Emp_Salary
Rajesh 01 25000
Mahesh 02  38000
Suresh 03  50000

As the “esh” string is present in every Column of the Emp_Name field, the search function returns a complete table.

#2. Power Apps Filter Function:

The Power Apps filter function is used to locate the records which fulfill a particular Formula or a condition.

Syntax:

Filter(Table, Formula)
  • Table: This field refers to the table to be searched.
  • Formula: Formula by each record of the table is assessed.

Example:

Emp_Name Emp_ID Emp_Salary
Rajesh 01 25000
Mahesh 02  38000
Suresh 03  50000

The Power Apps Filter function is applied to the above Employ Table in the following way:

Filter(Employ, Emp_Salary>25000)
 
Emp_Name Emp_ID Emp_Salary
Mahesh 02  38000
Suresh 03  50000

In the above Filter Function, we have applied a formula, i.e. Emp_Salary>25000, so the records which satisfied this formula are returned in the above Employ Table.

#3. Power Apps Lookup Function:

The Power Apps Lookup Function first locates a record based on the formula, and then it uses a reduction formula to reduce the record to a single value.

Syntax: Lookup(Table, Formula, ReductionFormula)

  • Table: This field indicates the table to be searched.

  • Formula: This field gives the formula to be applied to the table.

  • ReductionFormula: This field reduces the returned record to a single value.

Example:

Emp_Name Emp_ID Emp_Salary
Rajesh 01 25000
Mahesh 02  38000
Suresh 03  50000

Now apply the Power Apps Lookup function on the above Employ Table

Lookup( Employ, Emp_ID=”03”, Emp_Salary)

 The above function says that we have to select the record which has the Emp_ID Value is equal to “03”, and then we have to display the Emp_Salary Value of that record. So, now the above function returns the following single Value:

“50000”-It is the Value of Emp_Salary of the employee who has Emp_ID as “03.”
