  The SAP error message CNVMBTRFC136 with the description "Connection state set to '&1'" typically relates to issues with Remote Function Call (RFC) connections in SAP systems, particularly in the context of data migration or conversion processes.
  Cause:
  
  Connection Issues: The error often indicates that there is a problem with the RFC connection between the systems. This could be due to network issues, incorrect configuration, or the target system being unavailable.
  State Management: The message indicates that the connection state has changed, which could be due to a timeout, an error in the connection, or a manual intervention that altered the connection state.

  Solution:
  
  
  Check RFC Connection:

  Network Connectivity:

  User Credentials:
  
  Verify that the user credentials used for the RFC connection have the necessary authorizations and are not locked or expired.
  
  
  
  Review Logs:
