• What is the cause and solution for SAP error message WRF_FOLUPART026 - Follow-up/replacement material & is a reference material ?

  SAP Error Message:
  
  WRF_FOLUPART026 – Follow-up/replacement material & is a reference material
  
  Cause:
  This error occurs when you try to assign a follow-up or replacement material that is defined as a reference material in SAP. Reference materials are typically used for informational or classification purposes and are not intended to be used as follow-up or replacement materials in processes like production orders, sales orders, or material master data maintenance.
  In other words, the system prevents you from linking a follow-up or replacement material if that material is flagged as a reference material because such materials are not valid for transactional or operational use.
  
  Explanation:
  
  Reference Material: A material flagged as reference is usually used for documentation, classification, or informational purposes. It is not a "real" material for production or sales.
  Follow-up/Replacement Material: These are materials that replace or follow up on another material in processes such as order processing, production, or inventory management.
  
  SAP enforces this check to maintain data integrity and process correctness.
  
  Solution:
  
  
  Check the Material Master:
  
  Go to transaction MM03 (Display Material).
  Enter the follow-up/replacement material number.
  Check if the material is flagged as a reference material (this can be in the Basic Data or Classification views depending on configuration).
  
  
  
  If the material should not be a reference material:
  
  Change the material master to remove the reference material flag.
  Use transaction MM02 (Change Material) to update the material master.
  Save the changes.
  
  
  
  If the material is correctly a reference material:
  
  Do not assign it as a follow-up or replacement material.
  Choose a valid material that is not flagged as a reference material.
  
  
  
  Review Business Process:
  
  Confirm that the business process or master data setup aligns with the intended use of materials.
  Ensure that follow-up/replacement materials are valid operational materials.
  
  
  
  
  Related Information:
