The "Retry Scope" activity retries the activity contained in "Action" when conditions are not met, or an error is thrown. If the specified number of retries is reached and an error still occurs, the activity throws an error. The behavior upon throwing an error depends on the value set in the "Continue on Error" property in the Properties panel.

Note: Confirmed Studio version with tested operation: 2.0.1.6
Note: Terminology may vary depending on the version.

Property Section	Property Name	Input Field	Description

Input	Retry Interval	Enter Value (TimeSpan)	Specifies the interval between each retry (in seconds).

4. Usage

Drag and drop the activity "Core > Retry Scope" from the Toolbox to the Designer panel.

Set the number of retries and the retry interval. In this example, we set the interval to retry every 5 seconds, a total of 3 times. Specify the retry count as "3" in the Properties panel under "Input > NumberOfRetries." Set the retry interval as "00:00:05" under "Input > Retry Interval."

Describe the process to retry upon error within "Action." Drag and drop the "Core > Delete" activity from the Toolbox to the Designer panel.

In the Properties panel for "Input > Target Path," specify the variable name containing the file name to delete, such as "C:\Users\VanTT20\Desktop\big-image.png"

Click "Home > Start" or press the "F5" key to execute.

Execution Result:
Since the target file does not exist, it performs execution every 5 seconds, up to 3 times.
