How to "Add" a combo key of 3 fields from a page into other pages ?

Question

Folks,
Hello. My PeopleSoft component has 5 pages. Its layout looks like below:
AddJournal     Header          Lines          Total           Error
"AddJournal" is the first page that has 3 fields: OperatingUnit, ID, Date. The 3 fields is also a combo key that appears in the next 4 pages "Header", "Lines", "Total" and "Error" to maintain data consistency and identify the transaction.
I am working on a push button "Add" in the "AddJournal" page. The button should do 2 things:
First, when click on button "Add", it inserts the values of 3 fields into its underlying "AddJournal" table in Database.
Second, after click on the button, the value of 3 fields also appear on the next 4 pages "Header", "Lines", "Total" and "Error". All the other 4 pages' underlying Database tables contain the 3 fields.
I understand how to achieve the first function by using push button properties "Scroll Action" and "Row Insert". But don't understand how to achieve the second function.
Does any folk understand how to do the second function ?
Do I need to redesign the Database tables for the next 4 pages to achieve the second function ?
Thanks.

There is a lot here, and I think we will need more information to help.
FieldChange Event:
The FieldChange event occurs when you change that particular field. So, assuming the PeopleCode works correctly, it will copy the values of those three fields at the time just after you change the OperatingUnit. So, take this example:
-all three fields are blank
-You change the OperatingUnit to "OU"
-You change the ID to "XX"
-You change the Date to "04/23/2010"
The values that would be copied to the other pages would be "OU", blank, and blank because that is what they were just after changing OperatingUnit to "OU"
Does that make sense?
Page Design:
Normally, the keys are automatically populated for you. Header and Line sound like a parent-child relationship. So, if your page is designed correctly, the keys should be carried over automatically for you. If the tables are all sibling tables you will need the PeopleCode. I don't know if you want to explore the page design issue at all, but that might solve your problem without the PeopleCode.
In any case, it would help if you would post the page structure. First of all, what occurs level are the three tables at? You can tell on the Order tab of the page -- I believe it is the far left column.
PeopleCode:
Can you post your PeopleCode, and maybe we can spot something in the PeopleCode that is not right? If you are unsure if and when your PeopleCode is running, you can place a winmessage function in there. Put something like this:
WinMessage("Hello!");
You should see the hello message after you change the Operating Unit field. With deferred processing, you may not see it until you hit Save or Refresh.
