• What is the cause and solution for SAP error message GT278 - RFC connection could not be closed ?

  The SAP error message GT278, which states "RFC connection could not be closed," typically indicates an issue with the Remote Function Call (RFC) connection between SAP systems or between an SAP system and an external system. This error can arise due to various reasons, including network issues, configuration problems, or resource limitations.
  Causes:
  
  Network Issues: Problems with the network connection can prevent the RFC connection from being closed properly.
  Timeouts: If the RFC connection is idle for too long, it may time out, leading to issues when trying to close it.
