The following guides describe how to customize the out-of-the-box implementation of Windchill Enterprise Systems Integration (Windchill ESI) and ERP Connector. They are intended for developers who are familiar with Windchill, TIBCO and Windchill ESI.

These documents provide high-level guidance to those considering customizing Windchill ESI and ERP Connector. They are not intended to be prescriptive or extensive. Customization should not be undertaken lightly. Customization can have a major impact on technical support, maintenance, and future upgrades. The costs and benefits of a customization should be carefully analyzed with an experienced systems integrator prior to moving forward. Also, you should discuss the Windchill ESI product roadmap with your PTC representative to determine if future product releases will include the desired functionality. Customizing Windchill ESI or ERP Connector must be viewed from an end-to-end system perspective. Windchill ESI consists of many components organized in a layered architecture. Customizations generally cannot be confined to a single component or module, due to the many interrelationships and dependencies between components. In other words, you should carefully consider the downstream effects of any modifications to the standard Windchill ESI product.
