  Certainly! Here's a detailed explanation regarding the SAP error message VH129 - "Conditions from (milestone) billed items can not be changed":
  
  Error Message: VH129
  Text: Conditions from (milestone) billed items can not be changed
  
  
  Cause:
  This error occurs in SAP Sales and Distribution (SD) or Contract Billing scenarios when you attempt to change pricing conditions on a billing document or sales document item that has already been milestone billed or partially billed.
  
  Milestone Billing: In milestone billing, billing is done based on predefined milestones rather than on delivery or order quantity. Once a milestone is billed, the system locks the pricing conditions related to that milestone to ensure billing consistency.
  Condition Change Restriction: SAP does not allow changes to pricing conditions (such as discounts, surcharges, or prices) for items that have already been billed via milestone billing because it would lead to inconsistencies between the billed amount and the contract or sales document.
