• What is the cause and solution for SAP error message WS_MASS034 - New Message Determination Incorrect ?

  Certainly! Here's a detailed explanation regarding the SAP error message WS_MASS034: New Message Determination Incorrect:
  
  Error Message
  WS_MASS034: New Message Determination Incorrect
  
  Cause
  This error typically occurs in the context of mass processing of messages in SAP (such as mass output processing in Sales and Distribution or other modules where message determination is used). The system is unable to determine a valid new message determination procedure for the document or object being processed.
  Possible causes include:
  
  The message determination procedure assigned to the document or master data is missing or incorrectly configured.
  The condition records for message determination are incomplete or missing.
  The output type or message type is not properly maintained or assigned.
  The customizing for message determination (e.g., in SD: Output Determination procedures) is inconsistent or incomplete.
  The system is trying to switch to a new message determination procedure that is not valid or not assigned to the relevant application or document type.
  In case of migration or upgrade, the new message determination procedures might not be properly set up or activated.
  
  
  Solution
  To resolve the WS_MASS034 error, follow these steps:
  
  
  Check Message Determination Procedure:
  
  Verify the message determination procedure assigned to the document type or master data.
  In SD, check the output determination procedure in transaction NACE or the newer message determination framework (e.g., BRF+ based message determination).
  Ensure that the procedure is correctly assigned and active.
  
  
  
  Verify Condition Records:
  
  Check if condition records exist for the output types involved.
  Use transaction VV31 (Create Condition Records) or VV32 (Change Condition Records) to verify.
  
  
  
  Check Output Types and Message Types:
  
  Confirm that the output types are correctly configured and assigned to the message determination procedure.
  Ensure that the output types are valid for the document type and application.
  
  
  
  Review Customizing for Message Determination:
  
  In SD, use NACE or the relevant customizing path:
  
  For Sales Documents: SPRO ? Sales and Distribution ? Basic Functions ? Output Control ? Message Determination Procedures.
  
  
  For other modules, check the corresponding customizing.
  
  
  
  Check for New Message Determination Framework:
  
  If your system uses the new message determination (e.g., BRF+), ensure that the BRF+ application and rules are correctly configured and active.
  Use transaction BRF+ to check the rules.
  
  
  
  Mass Processing Settings:
  
  If the error occurs during mass processing (e.g., mass output), check the selection criteria and ensure that the documents selected have valid message determination procedures.
  
  
  
  Debugging / Logs:
  
  If the above steps do not resolve the issue, debug the message determination logic or check application logs (transaction SLG1) for more detailed error information.
