Displaying Entity Level Attributes on Summary screen

Question

Hi
Is there a way to show the value of an entity level attribute on the summary screen?
I need the attribute values for all entity instances to be listed on the summary screen.
For example, I have a household member entity and I need to display on the summary screen the names of all
the household members who are above 18 years of age.Is this possible?
Thanks,
Lokesh

Out-of-the-box in version 10, no, you can't attach entity level attributes to the summary screen.
The new InstanceValueIf function in 10.1 can be used to partially address the issue of wanting to display entity level information on the summary screen. Basically, you can use this function to move a text value from an entity level to the Global level, and that new Global attribute can then be attached to the summary screen.
Rule syntax:
InstanceValueIf(<the relationship>, <the value expression>, <the condition expression>)
Example rule:
the name of the oldest child = InstanceValueIf(the children, the child's name, the child's age = the age of the oldest child)
InstanceValueIf: http://www.oracle.com/technology/products/applications/policy-automation/help/opm10_1/Content/Reference/Rule%20syntax%20reference/Entity_and_relationship_functions.htm
However, this function only works where there is only one entity instance which satisfies the conditional expression. Therefore it wouldn't work for your example as presumably there could be multiple household members who are above 18 years of age.
You could consider attaching a Global level attribute on the summary screen ("there are household members who are above 18 years") which has a decision report listing the people who satisfy the criteria, e.g.
there are household members who are above 18 years if
…..ForAll(the household members, the household member's age is known) and [invisible]
…..Exists(the household members, the household member is above 18 years of age) [silent]
the household member is above 18 years of age if
.....the household member's age > 18
(Note that I've used the silent and invisible parameters in the first rule to trim the decision report.)
Imagine the following 4 household members:
Homer, aged 38
Marge, aged 36
Bart, aged 10
Lisa, aged 8
Assuming you've set up name substitution in the rule project, the decision report will say "Homer is above 18 years of age" and "Marge is above 18 years of age". As this is the decision report, it won't be displayed directly on the summary screen, but will be accessible via the [Why?] link. This might be as close as you'll get using only out-of-the-box functionality and no customisation.
