• What is the cause and solution for SAP error message WES_OUTBOUND322 - System does not send blank messages ?

  SAP Error Message:
  
  WES_OUTBOUND322 System does not send blank messages
  
  Cause:
  This error occurs when the SAP system attempts to send an outbound IDoc (Intermediate Document) or message that contains no data segments—essentially, a "blank" message. The system is designed to prevent sending empty IDocs because they do not carry any meaningful information and can cause processing issues downstream.
  Common scenarios leading to this error include:
  
  The data selection or extraction logic results in no data to send.
  Incorrect partner profile or message type configuration causing no segments to be filled.
  Filters or conditions in the outbound processing that exclude all data.
  Custom enhancements or user exits that inadvertently clear all segments.
  
  
  Solution:
  To resolve the WES_OUTBOUND322 error, follow these steps:
  
  
  Check the Data Source:
  
  Verify that the data intended for the IDoc actually exists.
  Run the selection or extraction program manually to confirm data presence.
  
  
  
  Review Partner Profile and Message Type Configuration:
  
  Use transaction WE20 to check the partner profile settings.
  Ensure the outbound parameters (message type, process code) are correctly set.
  Confirm that the message type is assigned to the correct IDoc type and that segments are properly defined.
  
  
  
  Analyze the IDoc Generation Logic:
  
  If custom code or user exits are involved, debug or review them to ensure they do not clear all segments.
  Check for any filters or conditions that might exclude all data.
  
  
  
  Test IDoc Creation:
  
  Use transaction WE19 (IDoc test tool) to create a test IDoc with data.
  Confirm that the system can generate and send a non-blank IDoc.
  
  
  
  Adjust or Remove Filters:
  
  If filters or selection criteria are too restrictive, modify them to allow data to be included.
  
  
  
  Check for Notes or SAP OSS Messages:
  
  Sometimes SAP releases notes related to specific message types or modules that address this issue.

  Transaction Codes:
  
  WE20 – Partner Profiles
  WE19 – IDoc Test Tool
  WE02 / WE05 – IDoc Display and Monitoring
  BD87 – Reprocess IDocs
  
  
  
  IDoc Basics:
  
  IDocs must contain at least one data segment to be valid.
  Blank IDocs are rejected to avoid unnecessary processing and errors in receiving systems.
  
  
  
  SAP Notes:
  
  Check SAP Support Portal for notes related to WES_OUTBOUND322 or outbound IDoc processing issues.
  
  
  
  Debugging:
  
  Use debugging tools to trace IDoc creation and identify where data is lost or not populated.
  
  
  
  
  Summary:
  The WES_OUTBOUND322 error indicates that the system is trying to send an empty IDoc message. The fix involves ensuring that the outbound process actually generates data segments by verifying data availability, configuration, and any custom logic involved in IDoc creation. Proper configuration and data presence will prevent this error.
