A break inside a loop will only break the loop and continues with the actions on the right side outside the loop.
If you don't want the outside-the-loop actions being executed just remove them or use a variable type boolean created before the loop and changed inside the loop just before the break. Then you can place a condition around the actions outside the loop.
A printscreen of your microflow will help in giving a better answer.
you mean this?
Hi Muhammad,
The Break event only interrupts the current loop, not the entire microflow. So it is expected behavior that it continues with the rest of the microflow after the break event. I see you are already creating a boolean variable that you change in the loop. If you want the microflow to stop after using a break event, create an expression after the loop that checks for the boolean variable and ends the microflow if the boolean is false.
