ESI is the primary route to integrate information in windchill with downstream systems. When a company installs the SUMA package it is to manage AML and AVL for their Buy parts. Without the ability to include these lists and their information in the ESI, we are forced to customize the Renderers available to get the information downstream. The relationship between Parts and Supplier Parts is one to many and we cannot represent that relationship elegantly in the ESI xml when we must extend something like the WTPartRenderer and try to force it into a flat xml state.
Please support AXLEntries in the ESI solution and also include the objects that link to the AXLEntry object so that the XML is formatted similarly to other linked objects in the ESI.
