  SAP Error Message:
  
  WER_UI122: Operation can only be performed on the main condition
  
  Cause:
  This error occurs when an operation intended only for the main condition in a pricing procedure is attempted on a subcondition or a condition that is not the main condition. In SAP pricing, certain operations (like changing or deleting) are restricted to the main condition because subconditions depend on or are derived from the main condition.
  For example, if you try to manually change or delete a condition record that is a subcondition (such as a discount or surcharge condition linked to a main price condition), the system will throw this error.
  
  Explanation:
  
  Main condition: The primary condition in a pricing procedure, usually the base price or main price element.
  Subcondition: Conditions that depend on or modify the main condition, such as discounts, surcharges, taxes, or freight.
  
  Operations like changing the value, deleting, or certain updates are only allowed on the main condition to maintain pricing integrity.
  
  Solution:
  
  
  Identify the condition type:
  
  Check which condition you are trying to operate on. Ensure it is the main condition in the pricing procedure.
  
  
  Perform operation on the main condition:
  
  If you need to change or delete a condition, do it on the main condition record, not on subconditions.
  
  
  Review pricing procedure:
  
  Verify the pricing procedure configuration to understand which condition types are main and which are subconditions.
  
  
  Adjust your process:
  
  If your business process requires changes on subconditions, consider if the process or customization needs adjustment, or if the operation should be done differently (e.g., changing the main condition or adjusting condition records in a different way).
  
  
  Check user exits or custom code:
  
  If this error appears during custom developments or user exits, ensure that the code respects the restriction and only performs operations on main conditions.
