Sure. In the Flow Decision
You are using the rerun flag(boolean variable TRUE/FALSE) to check weather the robot should be ran again.
If rerun = TRUE, then robot will run again
If rerun = FALSE, then robot will stop afte the execution.
In the screenshot I presented you a simple workflow with 3 variables
rerun (boolean) = false ← boolean will always have it’s default value set to FALSE
count (int) = 0
rerunMaxCount (int) = 3
Whenever the exception happens in your program (inside the Try segment), robot will go to Catches segment.
Robot will check if condition (if count < rerunMaxCount)
When this condition is true, robot will set the rerun variable to True.
rerun = true
This means that exception happened and you want to run your program once more.
However, if your program fails due to some software or data problem, it would try to run infinitely(because every time exception happens the rerun will be set to true).
That’s why we add +1 to count variable every time exception happens.
First time exception happens: count = 0, rerunMaxCount = 3 => count < 3
Second time: count = 1, rerunMaxCount = 3 => count < 3
Third time: count = 2, rerunMaxCount = 3 => count < 3
Fourth time: count = 3, rerunMaxCount = 3 => count = 3
At fouth attempt, the condition in IF statement won’t be satisfied and robot will assign FALSE to rerun variable. This way robot will stop working. It’s just a safe mechanism.
The rerun = False inside of Try segment after your program is set in case that the program fails once and next time it run correctly so you don’t want to rerun it again.
