Authentication to SAP Systems
TIBCO accesses the SAP distribution target through the user name (ESISYS) and a password specified in the adapter instance deployment configuration. This user name is configured in the distribution target at implementation time. In other words,Windchill ESI does not support dynamic logon to the ERP distribution target. The ERP distribution target logon information for the adapter is also specified at the time of implementation.
