  Certainly! Here's a detailed explanation for the SAP error message WZ385 Could not be sent: RFC problem:
  
  Error Message
  WZ385 Could not be sent: RFC problem
  
  Cause
  This error occurs when an SAP system tries to send a message (such as a workflow message, IDoc, or any communication that relies on Remote Function Call - RFC) to another system or client, but the RFC connection fails. The failure can be due to several reasons:
  
  The RFC destination is not correctly configured or is inactive.
  Network issues preventing communication between the sender and receiver systems.
  The target system is down or not reachable.
  Authorization problems for the user executing the RFC.
  Incorrect or missing parameters in the RFC destination.
  SAP Gateway issues on either the sending or receiving system.
  Version incompatibility or patch level issues between systems.
  
  
  Solution
  
  
  Check RFC Destination:
  
  Go to transaction SM59.
  Test the RFC destination used for sending the message.
  If the test fails, check the configuration (target host, system number, user credentials, etc.).
  Correct any errors and retest until successful.
  
  
  
  Check Network Connectivity:
  
  Ensure that the network connection between the two SAP systems is active.
  Use ping or telnet to verify connectivity to the target host and port.
  
  
  
  Check SAP Gateway Status:
  
  Use transaction SMGW to check the gateway status on both sender and receiver systems.
  Restart the gateway if necessary.
  
  
  
  Check User Authorizations:
  
  Verify that the user configured in the RFC destination has the necessary authorizations to execute the required functions.
  Use transaction SU53 after a failed RFC call to check authorization failures.
  
  
  
  Check System Logs:
  
  Use transaction SM21 to check system logs for any related errors.
  Also check ST22 for any dumps related to the RFC call.
  
  
  
  Check for Locked or Inactive Users:
  
  Ensure the user in the RFC destination is not locked or expired.
  
  
  
  Review Message or Workflow Configuration:
  
  If this error occurs in the context of workflow, check the workflow logs (transaction SWI1 or SWIA) for more details.
  Verify that the workflow container and binding are correct.
  
  
  
  Apply SAP Notes:
  
  Search the SAP Support Portal for notes related to RFC problems and message WZ385.
  Apply any relevant patches or corrections.

  RFC Types:
  
  Connection types like 3 (ABAP connection), T (TCP/IP connection), etc., should be verified.
  
  
  
  Common RFC Issues:
  
  Mismatched SAP kernel versions.
  Incorrect SNC (Secure Network Communication) settings.
  Expired passwords for RFC users.
  
  
  
  
  Summary
  The WZ385 Could not be sent: RFC problem error indicates a failure in the remote communication between SAP systems. The primary step is to verify and test the RFC destination in SM59, check network and gateway status, and ensure proper authorizations. Resolving the underlying RFC connectivity or configuration issue will fix the error.
