Present a record by date through an Abap Rutine

Question

Hi Gurus,
i got in the cube the next records for example:
calday Material Quantity
01.01.2011 A 10
15.01.2011 A 20
if i present in the query these IO an KF the query will show these 2 records, now i want just show the last record by date
calday Material Quantity
15.01.2011 A 20
i tried in the query with a calculate KF with exception aggregation , MAX with Reference to calday , but, i need to show 0CALDAY for that reason this doesnt work, so i was thinking in an ABAP  rutine that read all the active table of the ODS and compare record by record whats the last date by material and this record must be marked with a vaalue in another Infoobject, before the load to the cube, then i filter in the query for this mark IO, now how will the code be? can you help  to build this code, or some advice or idea?,  i appreciate it

Thanks for helping me.
Currently, my application provides users a feature to sort all the ThreadBean retrieved from the database according to two criteria:
1. sort by
thread_last_post_date, thread_creation_date, message_sender, thread_reply_count, thread_view_count
2. order by DESC or ASC
Therefore, my existing query string looks like:
String query = "SELECT ...... FROM message_thread WHERE message_receiver = ? ORDER BY " + sort + " " + order;According to your advice, I simply add another criterion; say, articleTitle to my query string.
A. Will this added criterion articleTitle have any impact on the feature that the application provides to users; namely, sort and order? (Now, all messages will be presented to users in categories; i.e. articleTitle.)
B. Where should I add the articleTitle to the query string
B.1: before sort and order?
String query = "SELECT ...... FROM message_thread WHERE message_receiver = ? ORDER BY " + articleTitle + " " + sort + " " + order;or
B.2: after sort and order?
String query = "SELECT ...... FROM message_thread WHERE message_receiver = ? ORDER BY " + sort + " " + order + " " + articleTitle;
