• What is the cause and solution for SAP error message WRF_ARTICLE_SCREENS093 - Cannot delete; PSM code &1 is already used in material ?

  SAP Error Message:
  
  WRF_ARTICLE_SCREENS093 Cannot delete; PSM code &1 is already used in material
  
  Cause:
  This error occurs when you attempt to delete a PSM (Product Structure Management) code that is currently assigned to one or more materials in the system. The system prevents deletion because the PSM code is still in use and linked to existing material master records or product structures.
  
  Explanation:
  
  PSM code: Typically refers to a classification or categorization code used in product structure or material master data.
  When a PSM code is assigned to a material, it forms part of the material's identification or classification.
  Deleting such a code without first removing or reassigning it from all materials would lead to data inconsistencies.
  Hence, SAP enforces this check and throws the error to prevent deletion.
  
  
  Solution:
  
  
  Identify materials using the PSM code:
  
  Use transaction codes like MM03 (Display Material) or custom reports to find all materials assigned with the PSM code.
  Alternatively, use database queries or standard SAP reports to list materials linked to the PSM code.
  
  
  
  Remove or change the PSM code assignment:
  
  For each material using the PSM code, either:
  
  Remove the PSM code assignment if no longer needed.
  Or assign a different PSM code if applicable.
  
  
  
  
  
  After all materials are updated:
  
  Retry deleting the PSM code.
  The system should now allow deletion since the code is no longer in use.
  
  
  
  
  Additional Information:
  
  Check dependencies: Sometimes, PSM codes might be linked not only in material master but also in BOMs (Bill of Materials), classification data, or other product structure elements.
  Authorization: Ensure you have the necessary authorization to modify material master data and delete PSM codes.
  Backup: Before mass changes, consider backing up data or performing changes in a test environment.
  Customizing: If this error appears in a custom development or add-on, check the relevant user-exits or BAdIs that might enforce this validation.
