  Adjust Settings:
  
  If both fields are set, you need to decide which one you want to use based on your planning requirements.
  Clear the field that you do not want to use. For example, if you want to use the Advanced Planning Indicator, ensure that the ARun field is blank.
  
  
  
  Save Changes:
  
  After making the necessary adjustments, save the changes to the material master.
