Resolving a 1:n Association to a single row


I have a requirement wherein there are 2 BOs, and the first BO has a 1:n association to the other BO. On the UI, I want to show fields from both the BOs in ONE row, but after resolving 1 particular instance.

For eg: If the 2nd BO has 3 records, and only one of them is valid for the period I login, I should pick up only that record and show its fields along with other fields of the first BO.

BO1                                               BO2

ID, Desc, Type                              ID, BO1 ID, Current valid Indicator    Amount

01     Test1   A                               1,    01,           True,                                   1000

                                                       2,   01,           False,                                  2000

                                                       3,   01,           False,                                  3000


ID    Desc    Type     ID   Amount
01    Test1    A          1    1000

Although there are 3 records for the ID 01 of the BO1 via association to BO2, I should pick up only the first record to show on the UI. How should one resolve a 1:n association in UI designer ?

Kind Regards
