  The SAP error message SHDB_PFW702, which indicates an "RFC Communication Failure," typically occurs during the execution of a batch input session or when using the transaction SHDB (Batch Input Recorder). This error can arise due to various reasons related to Remote Function Call (RFC) communication issues between the SAP system and other systems or components.
  Causes of SHDB_PFW702 RFC Communication Failure
  
  
  Network Issues: Problems with the network connection between the SAP application server and the database or other systems can lead to RFC communication failures.
  
  
  System Configuration: Incorrect configuration of RFC destinations in the SAP system can cause communication failures. This includes issues with the connection parameters or the target system being down.
  
  
  Authorization Issues: The user executing the batch input session may not have the necessary authorizations to perform the required actions, leading to communication errors.
  
  
  System Load: High load on the SAP system or the target system can lead to timeouts or failures in establishing RFC connections.
  
  
  Transport Layer Issues: Problems with the transport layer, such as issues with the SAP kernel or middleware, can also result in RFC communication failures.
  
  
  SAP Notes: There may be specific bugs or issues documented in SAP Notes that relate to the version of SAP you are using.
