  Text: Hierarchy structure: &1
  
  1. Cause
  The error message WXCM026 typically occurs in the context of SAP Classification and Characteristics, particularly when dealing with hierarchy structures in the Classification system (e.g., Class Hierarchies, Characteristic Hierarchies).
  
  The placeholder &1 is replaced by the name or ID of the hierarchy structure involved.
  The message usually indicates that there is an issue with the hierarchy structure being referenced or processed.
  Common causes include:
  
  The hierarchy structure does not exist or is not defined in the system.
