• What is the cause and solution for SAP error message /SCWM/UI_RF004 - Recursion in menu hierarchy is forbidden ?

  The SAP error message /SCWM/UI_RF004 Recursion in menu hierarchy is forbidden typically occurs in the context of SAP Extended Warehouse Management (EWM) when there is an issue with the configuration of the user interface (UI) menu hierarchy. This error indicates that there is a recursive reference in the menu structure, which is not allowed.
  Cause:
  
  
  Recursive Menu Structure: The most common cause of this error is that the menu items in the UI configuration are set up in such a way that they reference each other, creating a loop. For example, if Menu A points to Menu B, and Menu B points back to Menu A, this creates a recursion that the system cannot resolve.
  
  
  Incorrect Configuration: This can also happen if there are errors in the configuration of the roles or authorizations that define the menu structure.
  
  
  Solution:
  
  
  Check Menu Configuration:
  
  Go to the SAP GUI and navigate to the transaction code for the UI configuration (e.g., /SCWM/IMG).
  Review the menu structure to identify any recursive references. Ensure that no menu item points back to itself or creates a loop with other menu items.
  
  
  
  Modify Menu Items:
  
  If you find any recursive references, modify the menu items to eliminate the recursion. This may involve changing the hierarchy or reassigning menu items to different parent items.
  
  
  
  Test Changes:
  
  After making changes, test the menu structure to ensure that the error no longer occurs. You can do this by logging in with the relevant user role and checking if the menu displays correctly.
  
  
  
  Check Authorizations:
  
  Ensure that the user roles and authorizations are correctly set up and do not inadvertently create recursive paths in the menu.
  
  
  
  Consult Documentation:
  
  If you are unsure about the configuration, refer to the SAP documentation or help resources for guidance on setting up the UI menu structure correctly.
