• What is the cause and solution for SAP error message RSM1143 - More data packets were sent than the specified number ?

  The SAP error message RSM1143, which states "More data packets were sent than the specified number," typically occurs in the context of data transfer processes, particularly when using the SAP Data Transfer Workbench or during data uploads via IDocs or other interfaces.
  Cause:
  This error usually arises when the number of data packets sent exceeds the limit defined in the configuration settings. This can happen due to:
  
  Configuration Issues: The maximum number of data packets allowed for a particular operation may be set too low.
  Data Volume: The volume of data being processed exceeds the expected limits, leading to more packets being generated than anticipated.
  Network Issues: Network interruptions or delays can cause packets to be sent multiple times, leading to an overflow.
  Program Logic Errors: There may be issues in the custom program or script that is responsible for sending the data packets.
  
  Solution:
  To resolve the RSM1143 error, you can take the following steps:
  
  
  Check Configuration Settings:
  
  Review the settings related to data packet limits in the relevant transaction or configuration area (e.g., in the Data Transfer Workbench or IDoc settings).
  Increase the maximum number of allowed data packets if necessary.
  
  
  
  Optimize Data Volume:
  
  If possible, reduce the volume of data being sent in a single operation. This can be done by splitting the data into smaller batches.
  
  
  
  Review Network Stability:
  
  Ensure that the network connection is stable and that there are no interruptions that could cause packet loss or duplication.
  
  
  
  Debug Custom Programs:
  
  If you are using a custom program to send data packets, review the logic to ensure that it is correctly handling the data and not inadvertently sending more packets than intended.
