  Causes of MY012 Error
  
  
  Material Locking: The material may be locked by another user or process. This can happen if someone is currently editing the material or if a background job is running that locks the material.

  Transaction Errors: The transaction used to unlock the material may have encountered an error or may not be executed correctly.
  
  
  Solutions
  
  
  Check Material Lock Status:
  
  Use transaction code SM12 to check for locks on the material. If another user or process is locking the material, you may need to wait until they release it or contact them to unlock it.

  Ensure that the user has the necessary authorizations to unlock materials. This can be checked in transaction SU53 or by consulting with your SAP security team.

  Make sure you are using the correct transaction code to unlock the material. The typical transaction for unlocking materials is MM02 (Change Material) or MM03 (Display Material).
  
  
  
  Check for Background Jobs:
  
  Verify if there are any background jobs running that might be locking the material. You can check this in transaction SM37.
  
  
  
  Consult SAP Notes:
