  Cause

  In SAP, characteristics are used in classification and variant configuration.
  An external characteristic is typically a characteristic that is linked or mapped to an external system or interface.
  The error usually arises during data exchange, integration, or when using certain functions that require external characteristic mapping.
  For example, when using BAPI or IDoc interfaces, or when integrating with external systems, the system tries to find an external characteristic corresponding to an internal one.
  If the mapping is missing, the system cannot proceed and throws this error.
  
  
  When does it occur?
