Summary :
SAP Note identifies long dialog response times in RF transactions primarily in environments utilizing HTTP/HTTPS for UI in EWM. Identified latency issues originate from the Internet Communication Manager (ICM) particularly during ABAP runtimes between 500ms to a few seconds. For systems running Kernel 700/701, latency can equal ABAP runtime, potentially doubling response times. Recommendations include adjusting kernel parameters (e.g., icm/backend_waittime_mult, icm/min_timeout_mpi) to optimize latency times detailed in Note 1307291. Changes should be analyzed in case of multiple applications sharing HTTP/HTTPS connections on the same kernel to avoid interruptions.
