UM055 - Details

• The SAP error message UM055, which states "Menu & refers to an external menu. No further entries possible," typically occurs when you are trying to add or modify entries in a menu that is linked to an external menu. This means that the menu you are working with is not fully maintained within the SAP system, and therefore, you cannot make further changes to it.
  
  Cause:
  
  External Menu Reference: The menu you are trying to edit is defined as an external menu, which means it is not stored in the SAP system but rather points to an external source or system.
  Menu Configuration: The menu might be configured in a way that restricts modifications, often due to system settings or authorizations.
  
  
  Solution:
  
  Check Menu Configuration: Verify the configuration of the menu in question. If it is indeed an external menu, you will need to make changes in the external system or configuration rather than within
