• What is the cause and solution for SAP error message BGRFC141 - Unit size is too big (see SAP Note 2772500) ?

  The SAP error message BGRFC141, which states "Unit size is too big," typically occurs in the context of background RFC (BGRFC) processing. This error indicates that the size of the data being processed exceeds the maximum allowable size for a BGRFC unit.
  Cause:
  The primary cause of this error is that the data being sent in a BGRFC unit exceeds the maximum size limit defined by the system. This can happen due to:
  
  Large Data Volume: The data being processed in a single BGRFC call is too large, which can occur if a large number of records are being sent at once.
  Configuration Limits: The system configuration may have limits set for the maximum size of BGRFC units, and the data being processed exceeds these limits.
  
  Solution:
  To resolve the BGRFC141 error, you can consider the following solutions:
  
  
  Reduce Data Size: Break down the data being sent into smaller chunks. Instead of sending a large volume of data in one BGRFC call, split it into multiple smaller calls that comply with the size limits.
  
  
  Check Configuration: Review the BGRFC configuration settings in your SAP system. You may need to adjust the parameters that define the maximum unit size. This can typically be done in transaction RZ10 or RZ11, depending on your system version.
  
  
  SAP Note 2772500: Refer to SAP Note 2772500 for specific guidance and recommendations related to this error. The note may provide additional insights, patches, or configuration changes that can help resolve the issue.
  
  
  Monitor BGRFC Queue: Use transaction SM58 to monitor the BGRFC queue and identify any problematic entries. This can help you understand which specific calls are causing the issue.
  
  
  Consult SAP Support: If the issue persists after trying the above solutions, consider reaching out to SAP Support for further assistance. They can provide more tailored guidance based on your specific system configuration and usage.
  
  
  Related Information:
  
  BGRFC: Background RFC is a mechanism in SAP that allows asynchronous communication between different SAP systems or between different processes within the same system.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM58 (for monitoring RFC calls) and RZ10/RZ11 (for configuration settings).
  Performance Considerations: When dealing with large data volumes, consider performance implications and ensure that your system is optimized for handling such loads.
  
  By following these steps, you should be able to address the BGRFC141 error effectively.
