• What is the cause and solution for SAP error message WS603 - No price determination communication structure found for the header ?

  SAP Error Message:
  
  WS603 - No price determination communication structure found for the header
  
  Cause:
  This error occurs during pricing in sales documents (e.g., sales orders, quotations) when the system cannot find the required communication structure for price determination at the document header level. The communication structure is a data structure that the pricing procedure uses to pass header data to the pricing function modules.
  Typically, this happens because:
  
  The pricing procedure or condition technique expects a specific communication structure for the header, but it is not defined or assigned.
  Custom or standard pricing function modules are called that require a communication structure which is missing or incorrectly configured.
  The sales document type or item category is not properly linked to the pricing procedure or communication structure.
  A user exit or BAdI related to pricing is trying to access or pass header data but the communication structure is not available.
  
  
  Explanation:
  In SAP SD pricing, communication structures are used to transfer data between the sales document and the pricing routines. For header-level pricing, the system uses a communication structure (e.g., SD_VBAK or a custom structure) to pass header data to the pricing function modules.
  If the system cannot find this structure, it cannot perform price determination correctly, resulting in the WS603 error.
  
  Solution:
  
  
  Check Pricing Procedure Assignment:
  
  Verify that the pricing procedure assigned to the sales document type and sales area is correct.
  Transaction: V/08 (Assign Pricing Procedure to Sales Document Type)
  Ensure the pricing procedure is properly maintained and active.
  
  
  
  Check Condition Technique Configuration:
  
  Go to transaction V/06 or V/07 and verify the condition tables and access sequences.
  Ensure that the condition types used in the pricing procedure are correctly configured.
  
  
  
  Verify Communication Structure:
  
  Check the communication structure assigned to the pricing procedure.
  In customizing, under Sales and Distribution ? Basic Functions ? Pricing ? Pricing Control ? Define Communication Structures for Pricing, verify that the communication structure for the header is maintained.
  The standard communication structure for header pricing is usually SD_VBAK.
  If a custom communication structure is used, ensure it is correctly defined and assigned.
  
  
  
  Check User Exits / BAdIs:
  
  If custom code is implemented in user exits (e.g., USEREXIT_PRICING_PREPARE_TKOMK or USEREXIT_PRICING_PREPARE_TKOMP) or BAdIs related to pricing, verify that the communication structure is correctly handled.
  Debug the pricing routine to see where the communication structure is expected but missing.
  
  
  
  Check Sales Document Header Data:
  
  Ensure that the sales document header data is complete and consistent.
  Missing or incorrect header data can cause the system to fail in finding the communication structure.
  
  
  
  Transport or System Issues:
  
  If this error appears after a transport or system upgrade, verify that all relevant customizing and development objects related to pricing communication structures have been transported correctly.

  Transaction Codes:
  
  V/08 - Assign Pricing Procedure to Sales Document Type
  V/06 - Condition Tables
  V/07 - Access Sequences
  V/08 - Pricing Procedure Assignment
  SE37 - Test function modules related to pricing
  SE80 or SE38 - Check user exits or BAdIs
  
  
  
  Related SAP Notes:
  
  Check SAP OSS notes for WS603 or pricing communication structure issues.
  Sometimes, SAP releases notes for specific versions or patches.
  
  
  
  Debugging:
  
  Debug pricing routines to identify where the communication structure is expected.
  Check the call stack and data passed to pricing function modules.
