• What is the cause and solution for SAP error message WS099 - Error in calculation schema &, no net value can be set for item & ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WS099 - Error in calculation schema &, no net value can be set for item &
  
  Cause:
  This error occurs during the pricing or condition calculation process in SAP Sales and Distribution (SD) or Materials Management (MM) when the calculation schema (pricing procedure) does not result in a net value for a particular item. In other words, after all condition types and calculations are applied, the system cannot determine a net price or net value for the item.
  Common causes include:
  
  Incorrect or incomplete pricing procedure: The pricing procedure assigned to the document or item is missing necessary condition types or steps.
  Missing or zero condition values: Condition records for key condition types (e.g., PR00 - price) are missing or zero.
  Incorrect condition exclusion or condition base: Conditions might be excluded or the base for calculation is zero, leading to no net value.
  Errors in condition types or formulas: Custom condition types or formulas in the pricing procedure might be incorrectly configured.
  Currency or unit of measure issues: Mismatches or missing currency/unit conversions can cause calculation failures.
  Item category or document type issues: Certain item categories or document types might not be properly supported by the pricing procedure.
  
  
  Solution:
  To resolve the WS099 error, follow these steps:
  
  
  Check the Pricing Procedure:
  
  Verify the pricing procedure assigned to the sales document or purchase order.
  Ensure all necessary condition types (especially the base price condition like PR00) are included.
  Confirm the sequence and calculation rules in the pricing procedure are correct.
  
  
  
  Verify Condition Records:
  
  Use transaction VK13 (Display Condition Records) to check if condition records exist for the relevant condition types and keys.
  Ensure that the condition values are not zero or missing.
  
  
  
  Analyze Pricing in the Document:
  
  Use transaction VA03 (Display Sales Order) or ME23N (Display Purchase Order).
  Go to the item pricing details and check the condition types and their values.
  Use the pricing analysis (click on the pricing button) to see where the calculation fails.
  
  
  
  Check Custom Formulas or Routines:
  
  If custom condition types or user exits are used, verify that the logic correctly calculates values.
  Debug or review user exits (e.g., USEREXIT_PRICING_PREPARE_TKOMK) if necessary.
  
  
  
  Currency and Unit of Measure:
  
  Ensure that the currency and unit of measure are consistent and correctly maintained.
  Check for any conversion factors that might be zero or incorrect.
  
  
  
  Review Item Category and Document Type:
  
  Confirm that the item category supports pricing.
  Check if the document type is correctly linked to the pricing procedure.
  
  
  
  Test with Standard Pricing Procedure:
  
  Temporarily assign a standard SAP pricing procedure to isolate if the issue is with customizations.
