• What is the cause and solution for SAP error message WZ591 - Valid for 1 new instance ?

  SAP Error Message:
  
  WZ591 - Valid for 1 new instance
  
  Cause:
  The message WZ591 typically appears in SAP when you are trying to create or maintain an object (such as a workflow, a task, or a configuration) that is only valid for one new instance. This means the object or configuration you are working with is restricted to a single instance and cannot be reused or instantiated multiple times.
  In many cases, this message is related to SAP Workflow or Business Object Repository (BOR) where certain workflow tasks or methods are designed to be instantiated only once per workflow instance or business object instance.
  
  Explanation:
  
  The message is a warning (W) rather than an error (E), so it does not necessarily stop processing but informs you about the limitation.
  It indicates that the object you are trying to use or create is valid only for one new instance.
  This often happens when you try to reuse a workflow container element, task, or method that is designed to be unique per instance.
  
  
  Solution:
  
  
  Check the Object Design:
  
  Review the workflow task or business object method to confirm if it is designed to be instantiated only once.
  If you need multiple instances, consider redesigning the workflow or business object to allow multiple instances or use a different task/method.
  
  
  
  Adjust Workflow Logic:
  
  If you are working in SAP Workflow, ensure that the container elements or tasks are not reused improperly.
  Create separate tasks or container elements if multiple instances are required.
  
  
  
  Consult SAP Documentation:
  
  Look up the specific workflow or business object method documentation to understand the intended usage and restrictions.
  
  
  
  Ignore if Appropriate:
  
  Since this is a warning, if the process works as expected and the limitation is understood, you may choose to ignore it.
