Configuration Assumptions
Windchill ESI assumes that your SAP distribution targets provide the APIs listed in the section titled SAP APIs and they are characterized as described in Appendix C.Windchill ESI may not work as designed unless any differences between these assumptions and your SAP distribution targets are resolved through configuration or customization of Windchill ESI, or SAP distribution targets, or both.

The detailed configuration steps and the screen examples provided in the section, "Installing Windchill ESI" in the Windchill Enterprise Systems Integration Installation and Configuration Guide - SAP are also based on these assumptions.
