• Key Concepts: 
  A WHILE loop is a type of loop in SAP Business Workflow that allows a workflow to repeat a set of steps until a certain condition is met. This type of loop is useful for tasks that require multiple iterations, such as checking for errors or waiting for a response from another system. 
  
  How to use it: 
  To use a WHILE loop, you must first define the condition that will trigger the loop. This can be done by setting a Boolean variable to true or false. Once the condition is set, the workflow will execute the steps within the loop until the condition is met. 
  
  Tips & Tricks: 
  When using a WHILE loop, it is important to ensure that the condition will eventually be met. If not, the workflow could become stuck in an infinite loop. Additionally, it is important to consider how long the loop will take to execute and whether it could cause performance issues.
