  The SAP error message GS120, which states "You cannot create using a reference for hierarchy maintenance," typically occurs when you are trying to create a new hierarchy node or object using a reference that is not allowed in the context of hierarchy maintenance. This error is often encountered in the context of SAP's Organizational Management (OM) or similar modules where hierarchical structures are maintained.
  Cause:

  Hierarchy Settings: The settings for the hierarchy maintenance may not allow the creation of new nodes using references. This could be due to configuration settings in the system.
