WRF_FOLUPART021 - Details

• SAP Error Message:
  WRF_FOLUPART021 Original material & is a generic material
  
  
  Cause:
  This error typically occurs in SAP when a process or transaction involves a material that is defined as a generic material, but the system expects an original (specific) material. In other words, the system is trying to use or reference a material that is marked as generic (often a placeholder or a template material) where a concrete, specific material is required.
  
  Generic Material: A material master record that is used as a template or placeholder, often without detailed specifications or batch management.
  Original Material: A specific, fully defined material with all necessary attributes.
  
  The error arises because certain processes (e.g., follow-up processing, goods movement, batch management, or production orders) require a specific material to ensure traceability, inventory management, or production accuracy. Using a generic material in these contexts is not allowed.
  
  When does it occur?
  
  During follow-up processing in logistics or production.
  When creating or processing documents
