  The SAP error message B1811 indicates that there is an issue with the configuration of a BAPI (Business Application Programming Interface) call where more than one receiving system has been specified. This typically occurs in scenarios where a BAPI is expected to interact with a single target system, but multiple systems have been defined, leading to ambiguity.
  Cause:
  
  Multiple Target Systems: The error arises when the BAPI call is configured to send data to more than one receiving system. This can happen if the configuration settings in the BAPI or the calling program are not set correctly.
  Incorrect BAPI Usage: The BAPI might be called in a way that does not conform to its expected parameters, leading to the system interpreting that multiple targets are specified.
  Configuration Issues: There may be issues in the configuration of the BAPI or the related RFC (Remote Function Call) destinations.
  
  Solution:
  
  Check BAPI Parameters: Review the parameters being passed to the BAPI. Ensure that only one receiving system is specified. If the BAPI is designed to work with a single target, make sure that the call reflects that.
  Review Configuration: Check the configuration settings for the BAPI in the SAP system. Ensure that the receiving system is correctly defined and that there are no conflicting settings.
  Debugging: If you have access to the ABAP code, you can debug the BAPI call to see what parameters are being passed and identify where the multiple receiving systems are being specified.
  Consult Documentation: Refer to the SAP documentation for the specific BAPI you are using. It may provide insights into the expected parameters and usage.
  Contact SAP Support: If the issue persists and you cannot identify the cause, consider reaching out to SAP support for assistance. They may provide additional insights or patches if it is a known issue.
  
  Related Information:
  
  BAPI Documentation: Each BAPI has specific documentation that outlines its parameters and expected usage. Reviewing this can help clarify how to properly call the BAPI.
  SAP Notes: Check SAP Notes for any known issues or updates related to the BAPI you are using. Sometimes, there are patches or workarounds available.
  RFC Configuration: If the BAPI involves RFC calls, ensure that the RFC destinations are correctly configured in transaction SM59.
