Only the child business objects are displayed in the Keep Relationship ASI property. Additionally there is no way to set the Keep Relationship flag for the grand child business objects in the WebSphere Adapter for PeopleSoft Enterprise V7.5, and lower in the EMD wizard.
The Keep Relationship property is only initialized with the child business objects. The grand child business objects are not processed.
Resolving the problem
This issue has been resolved in PeopleSoft Adapter Fix Pack version 22.214.171.124. This version provides EMD with the capability to list the child, and the grand child business object for the keep relationship property.
