Power Automate Fundamentals # 23: Usage of Bool Function in Power Automate

Power Automate Fundamentals # 23: Usage of Bool Function in Power Automate

 

Introduction:

In Power Automate, at times we need to take decision based on Boolean value, it could be string or Boolean value. As an example, Power outage variable with true value is considered for demonstration and then Bool function is used for condition validation.

 

Step 1:

Login to the required Power Apps environment using URL make.powerapps.com by providing username and password and click on Flows on the left-hand side as shown in the below figure.

Step 2:

After Step 1, Click on New Flow and select instant cloud flow and provide the trigger as Manually trigger a flow and click on Create as shown in the below figure.

Step 3:

After Step 2, name flow as Bool Function and take initialize variable and name it as Set Variable Power Outage with the following fields

Name :  Power Outage

Type :  String

Value : true

as shown in the below figure.

Step 4:

After Step 3, take condition branch and name it as Verify Power Outage value is true string value with the following condition

Condition : variables(‘Power Outage’)

operator : is equal to

value : true

as shown in the below figure

Step 5:

After Step 4, in the yes part take a compose variable and name it as Power Outage exists in the given area and provide

Input value :

Power Outage in the given area and the value is @{variables('Power Outage')}

As shown in the below figure

Step 6:

After Step 5, in the no part take another compose operation and name it as Power Outage Does not exist in the given area and provide

Input value :

Power Outage Not Exists in the given area and the value is @{variables('Power Outage')}

 

as shown in the below figure.

Step 7:

After Step 6, take compose variable and name it as Pass Power Outage Variable to bool function and provide bool function with the syntax

bool(value : any)

with value like below

Input : bool(variables('Power Outage'))

And click on ok / update as shown in the below figure.

Step 8:

After Step 7, take a condition variable and name it as Verify Power Outage value is true (bool) value and provide

Condition : @outputs('Pass_Power_Outage_Variable_to_bool_function')

Operator : is equal to

Value : true

 as shown in the below figure.

Step 9:

After Step 8, go to yes condition and take a compose action and name it as Power Outage exists in the given area - bool function and provide

Input : Power Outage in the given area and the value is @{outputs('Pass_Power_Outage_Variable_to_bool_function')}

 shown in the figure.

Step 10:

After Step 9, go to no condition and take a compose action and name it as Power Outage exists in the given area - bool function and provide

Input : Power Outage does not exist in the given area and the value is @{outputs('Pass_Power_Outage_Variable_to_bool_function')}

 shown in the figure.

Step 11:

After Step 10, you can see the results with string true condition flow moved to false part as  shown in the figure.

Step 12:

After Step 11, you can see the results with bool function true condition flow moved to true part as  shown in the figure.

Note:

  1. Make sure to save and run the flow whenever you try expressions.
  2. MS documentation is found at here

Conclusion: In this way we can use bool function to work on conditions.
