• What is the cause and solution for SAP error message B1087 - Partner system & is an R/2 system; function is not available ?

  The SAP error message B1087 indicates that the system is trying to access a function that is not available in an R/2 system. This typically occurs when there is an attempt to use a function or feature that is only available in R/3 or later versions of SAP, while the system in question is still operating on the older R/2 platform.
  Cause:
  
  Compatibility Issues: The function being called is not supported in the R/2 environment. R/2 is an older SAP system that does not have the same capabilities as R/3 or S/4HANA.
  Incorrect Configuration: There may be a configuration issue where the system is incorrectly set up to call functions that are not available in R/2.
  Integration Problems: If there is an integration with other systems (like R/3), the calls made to the R/2 system may be trying to access unsupported functions.
  
  Solution:
  
  Check Functionality: Review the functionality being called and ensure that it is supported in the R/2 environment. If it is not, you may need to find an alternative approach or function that is compatible.
  Update Configuration: If the configuration is incorrect, update it to ensure that only supported functions are being called from the R/2 system.
  Consult Documentation: Refer to SAP documentation for R/2 to understand the limitations and available functions. This can help in identifying alternative solutions.
  Upgrade Consideration: If feasible, consider upgrading to a newer version of SAP (like R/3 or S/4HANA) that supports the required functionality.
  
  Related Information:
  
  SAP R/2 vs. R/3: R/2 is a mainframe-based system, while R/3 is a client-server architecture that offers more features and capabilities.
  SAP Notes: Check SAP Notes for any specific patches or updates related to this error message.
  Support: If the issue persists, consider reaching out to SAP support for assistance, especially if you have a maintenance agreement.
  
  In summary, the B1087 error is a compatibility issue between the function being called and the capabilities of the R/2 system. The best approach is to verify the functionality and configuration, and if necessary, consider upgrading to a more modern SAP system.
