  The SAP error message ARUN_MAIN018 indicates that there is an issue with setting the Advanced Planning Indicator (Adv. plan. Ind.) and the ARun fields simultaneously for a specific material and plant combination. This error typically arises in the context of Advanced Planning and Optimization (APO) or similar planning scenarios in SAP.
  Cause:
  The error occurs when there is an attempt to set both the Advanced Planning Indicator and the ARun fields for a material in a specific plant. This is not allowed because these fields are mutually exclusive; you can only set one of them at a time. The Advanced Planning Indicator is used to determine whether a material is subject to advanced planning processes, while the ARun fields are used for other planning scenarios.
  Solution:
  To resolve this error, you need to ensure that you are not trying to set both the Advanced Planning Indicator and the ARun fields for the same material and plant. Here are the steps you can take:
  
  
  Check Material Master Data: Go to the material master data for the specified material and plant. Verify the settings for the Advanced Planning Indicator and the ARun fields.
  
  
  Adjust Settings: If both fields are set, decide which one you need based on your planning requirements. You will need to either:
  
  Remove the Advanced Planning Indicator if you want to use the ARun fields.
  Clear the ARun fields if you want to use the Advanced Planning Indicator.
  
  
  
  Save Changes: After making the necessary adjustments, save the changes to the material master data.
  
  
  Test the Changes: After making the adjustments, try to execute the planning process again to see if the error persists.
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like MM02 (Change Material) to access and modify the material master data.
  Documentation: Refer to SAP documentation or help files related to Advanced Planning and Optimization for more details on the implications of setting these fields.
