Summary :
This SAP Note addresses a common issue where SAP GUI users experience a severed connection error, typically noted as "XYZ: Connection to partner 'sapserver:sapdp00' broken". Two primary reasons are identified: a crash in the instance's dispatcher process or assorted network issues such as firewall timeouts, problematic routers, or WAN disruptions. If the dispatcher collapses, systemic analysis under component BC-CST-DP is recommended. For network concerns, using diagnostic tools like niping and reviewing SAP Notes 500235 and 155147 help in pinpointing troubles. Information from traces like dev_disp, errorlog.gui, and network analyses should be gathered and provided to SAP Support for further assistance.
