• What is the cause and solution for SAP error message SWF_RUN666 - Window of sub method &1->&2 not closed ?

  The SAP error message SWF_RUN666, which states "Window of sub method &1->&2 not closed," typically occurs in the context of workflow management in SAP. This error indicates that a sub-method (a method called within a workflow) has not properly closed its window, which can lead to issues in the workflow execution.
  Cause:
  
  Unclosed Dialog Window: The sub-method may have opened a dialog window (for example, a pop-up for user input) that was not closed properly before the workflow attempted to proceed.
  Error in Method Logic: There may be a logical error in the method implementation that prevents the window from closing.
  User Interaction: If the method requires user interaction and the user did not complete the required actions, the window may remain open.
  System Configuration: There could be configuration issues in the workflow or method settings that prevent proper execution.
  
  Solution:
  
  Check Method Implementation: Review the implementation of the sub-method to ensure that all dialog windows are properly closed after their use. This includes checking for any error handling that might skip the closing logic.
  User Interaction: Ensure that the workflow is designed to handle user interactions correctly. If user input is required, make sure that the workflow waits for the input before proceeding.
  Debugging: Use the SAP debugging tools to step through the workflow and identify where the window is not being closed. Look for any exceptions or errors that might be causing the workflow to skip the closing step.
  Workflow Configuration: Review the workflow configuration settings to ensure that they are set up correctly. This includes checking the method parameters and ensuring that they are being passed correctly.
