Summary :
To troubleshoot RFC communication errors between an ABAP system (client) and an external server program in SAP environments, the following steps should be executed: First, clear old trace files from both the external server and ABAP system. Then, activate RFC traces in the ABAP system via transaction SM59 and in the external server, ensuring appropriate settings are enabled based on Note 877979. Reproduce the error to gather detailed data, then deactivate the traces once completed. Save and archive the traces, documenting all relevant information for further analysis or for sharing with SAP support teams if external assistance is required.
