  SAP Error Message WS189
  Message Text:
  
  'Only Post Accrual Conditions' is not compatible with 'Post Tax Amounts'
  
  Cause
  This error occurs in SAP Sales and Distribution (SD) pricing when you try to combine two incompatible condition types in a pricing procedure:
  
  "Only Post Accrual Conditions": These are condition types that are meant to be posted only as accruals (e.g., conditions that affect accounting accruals but not immediate tax postings).
  "Post Tax Amounts": These are condition types that post tax amounts directly.
  
  The system does not allow a pricing procedure to contain both types simultaneously because the logic for posting accruals conflicts with the logic for posting tax amounts. This incompatibility leads to the WS189 error.
  
  When Does It Occur?
  
  During pricing procedure determination or pricing calculation in SD billing or sales order processing.
  When condition types with the indicator "Only Post Accrual Conditions" are combined with condition types that post tax amounts.
  Typically seen when customizing or modifying pricing procedures or condition types.
  
  
  Solution
  
  
  Review Pricing Procedure:
  
  Check the pricing procedure assigned to the sales document or billing type.
  Identify condition types flagged as "Only Post Accrual Conditions" and those that post tax amounts.
  
  
  
  Adjust Condition Types:
  
  Avoid combining condition types with the "Only Post Accrual Conditions" indicator with those that post tax amounts in the same pricing procedure.
  If both types are required, consider splitting the pricing procedure or redesigning the pricing logic.
  
  
  
  Check Condition Type Settings:
  
  In transaction V/06 (Condition Types), verify the settings for the condition types involved.
  The indicator "Only Post Accrual Conditions" is set in the condition type definition. Remove or adjust this if inappropriate.
  
  
  
  Consult with FI/CO and SD Teams:
  
  Since this involves accounting postings, coordinate with Finance and Controlling teams to ensure the pricing and posting logic aligns with business and accounting requirements.
  
  
  
  Testing:
  
  After adjustments, test the sales order or billing document creation to ensure the error no longer occurs.
