• What is the cause and solution for SAP error message 5M279 - You must give the company name when sending/receiving via RFC ?

  The SAP error message 5M279, which states "You must give the company name when sending/receiving via RFC," typically occurs in the context of Remote Function Call (RFC) communications between different SAP systems or between an SAP system and an external system. This error indicates that the company code (or company name) is required for the operation being performed, but it has not been provided.
  Cause:
  
  Missing Company Code: The most common cause of this error is that the company code is not specified in the RFC call. This can happen if the calling program or configuration does not include the necessary company code information.
  Configuration Issues: There may be issues in the configuration of the RFC destination or the function module being called, which may not be set up to handle the company code correctly.
  Authorization Issues: Sometimes, the user or system may not have the necessary authorizations to access the company code, leading to this error.
  
  Solution:
  
  Specify Company Code: Ensure that the company code is included in the RFC call. This can usually be done by modifying the parameters of the function module being called to include the company code.
  Check RFC Destination: Verify the configuration of the RFC destination in transaction SM59. Ensure that the destination is correctly set up and that the necessary parameters, including the company code, are configured.
  Review Function Module: If you are using a custom function module, check its implementation to ensure that it correctly handles the company code parameter. If it is a standard SAP function module, refer to the documentation to understand the required parameters.
  Authorization Check: Ensure that the user or system executing the RFC call has the necessary authorizations to access the specified company code. This can be checked in transaction SU53 after the error occurs.
  Debugging: If the issue persists, consider debugging the RFC call to trace where the company code is being omitted. This can help identify if the issue is in the calling program or in the configuration.
