Answer 1

One option I can think of to implement this would be to capture the Work Order No in a session scoped variable through a combination of aWhen-Validate-Item (WVI) and When-New-Item-Instance (WNII) triggers. The session scoped variable can be as simple as creating a Forms parameter object called "Prev_Work_Order" or by creating a Forms Package specification with session global variables. For the sake of simplicity, my suggestion will use a parameter object. I would normally use a Forms Package specification as this is the preferred method and it more memory efficient.
Here's the concept: The Item WVI trigger captures the value of the WORK_ORDER_NO. The Item WNII trigger sets the default value of the WORK_ORDER_NO.
Here is a code sample:
/* WHEN-VALIDATE-ITEM */
BEGIN
   IF :MY_BLOCK.Work_Order_NO IS NOT NULL THEN
      :Parameter.Prev_Work_Order := :MY_BLOCK.Work_Order_No;
   END IF;
END;
/* WHEN-NEW-ITEM-INSTANCE */
BEGIN
   IF :Parameter.Prev_Work_Order IS NOT NULL THEN
      :MY_BLOCK.Work_Order_No := :Parameter.Prev_Work_Order;
   END IF;
END;You could put additional checks in this code, but this gives you the basics to start with.
Hope this helps,
Craig
