Smart SAP Assistant

• What is the cause and solution for SAP error message SXMSF126 - Enter a maximum package size greater than 0 ?

  The SAP error message SXMSF126 indicates that the maximum package size for the message processing in the SAP Exchange Infrastructure (XI) or Process Integration (PI) is set to a value of 0 or is not defined. This error typically occurs when configuring the integration settings for message processing.
  Cause:
  The error arises when the configuration for the maximum package size is either missing or set to an invalid value (0). The maximum package size is a critical parameter that determines how much data can be processed in a single message package. If this value is not set correctly, the system cannot process messages as expected.
  Solution:
  To resolve the error, you need to set a valid maximum package size greater than 0. Here are the steps to do this:
  
  
  Access the Integration Builder:
  
  Go to the SAP Integration Builder (transaction code SXMB_IFR or SXI_MONITOR).
  
  
  
  Navigate to the Configuration:
  
  Find the relevant configuration for the message processing where the error is occurring.
  
  
  
  Set the Maximum Package Size:
  
  Look for the parameter related to the maximum package size. This is usually found in the configuration settings for the sender or receiver communication channel.
  Set the maximum package size to a value greater than 0 (e.g., 1000 KB or any other appropriate value based on your requirements).
  
  
  
  Save the Configuration:
  
  After making the changes, save the configuration.
  
  
  
  Restart the Communication Channel:
  
  If necessary, restart the communication channel to apply the new settings.
  
  
  
  Test the Configuration:
  
  Send a test message to ensure that the configuration is working correctly and that the error does not reoccur.
  
  
  
  Related Information:
  
  Documentation: Refer to the SAP Help Portal or the specific documentation for your version of SAP PI/XI for detailed information on configuring communication channels and message processing settings.
  Monitoring Tools: Use transaction codes like SXMB_MONI or SXI_MONITOR to monitor message processing and troubleshoot any further issues.
  Performance Considerations: When setting the maximum package size, consider the performance implications. A larger package size may improve throughput but could also lead to increased memory usage.
  
  If the problem persists after following these steps, it may be necessary to check for additional configuration issues or consult with your SAP Basis or PI/IX team for further assistance.
