Advanced-Table in Advanced-Table Query RN

Question

I'm having difficulty creating a query region in the inner table within an Advanced-Table in Advanced-Table relationship. The inner tables searchable items appear in the outer tables simple search region and an error is raised when I open the detail table. The error states that the the item is not defined in the outer table VO. The error is correct, the column does not exist in the outer table's VO. It only exists in the inner table's VO and I've indicated what VO instance the column exists in when defining the item in the inner table. So my question is why does OAF check for an item in the outer table's VO when I've told it that the item exists in the VO defined on the inner table's item attributes?
Thanks for any answers or pointers.

Answer 1

I have been working on attempting to allow a user to specify query criteria for an inner table. Is this possible?
This is all I've been able to locate on this topic in the R12 Developer's Guide.
"The inner table bears a master-detail relation with the outer table. For each master row, corresponding detail rows are displayed in an inner table. Users can control the rows in the inner table by defining additional search criteria to the criteria already defined in the view link, which relates the outer view object with the inner view object."
The second sentence implies that query criteria can, in fact, be provided for an inner table set of data.
Thanks,
