• What is the cause and solution for SAP error message MZ051 - Exception & has no characteristic reference ?

  The SAP error message MZ051 ("Exception & has no characteristic reference") typically occurs in the context of SAP's Variant Configuration (VC) or when dealing with characteristics in the material master. This error indicates that there is an issue with the configuration of a variant or characteristic that is expected but not found.
  Cause:
  
  Missing Characteristic Reference: The error usually arises when a characteristic that is expected in a configuration profile is not defined or is incorrectly referenced.
