• What is the cause and solution for SAP error message WRF_FOLUPART021 - Original material & is a generic material ?

  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 that require a specific material.
  In batch management or quality management processes where generic materials are not permitted.
  In scenarios involving serial numbers, batch numbers, or detailed tracking.
  
  
  Solution:
  
  
  Check Material Master Data:
  
  Verify if the material in question is marked as generic.
  Go to transaction MM03 (Display Material) and check the material type and attributes.
  
  
  
  Use a Specific Material:
  
  Replace the generic material with a specific, original material that has all required details.
  If the generic material is used as a placeholder, identify the correct material to be used in the process.
  
  
  
  Adjust Process or Configuration:
  
  If the process allows, modify the configuration to accept generic materials (not recommended unless business process allows).
  Consult with your SAP MM/PP/QM consultant to understand if the process can be adapted.
  
  
  
  Material Master Maintenance:
  
  If the generic material needs to be converted into a specific material, create or maintain the material master with all required details.
  Ensure batch management or serial number profiles are correctly assigned if needed.
  
  
  
  Check Customizing:
  
  Sometimes, the error is triggered by validation or user-exit/custom code that restricts generic materials.
  Review any custom developments or validations that enforce this rule.
  
  
  
  
  Related Information:
  
  Material Types: Generic materials often have specific material types (e.g., DIEN for services or custom types).
  Batch Management: Generic materials usually do not have batch management enabled.
  Production Orders: Production or process orders require specific materials for accurate costing and tracking.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  User Exits / BAdIs: Custom code might enforce restrictions on generic materials.
