How to populate node with in node

Question

Hi,
I have scnerio to populate a node which has Header and items.
For example Sales Order.
-> Order
!-> Order No.
|-> Items
-> Item_No
-> Material No
-> Quantity
-> Price
Order cardinality is 1..n
Order can have more than one item, so cardinality is 1..n for item.
How I can populate Order node, with a single order No. and multiple items.
Cheers,
Senthil

HI Senthil,
Since one order can have more than one items, the best way is to create a node (<b>Order</b>) with cardinality 0.N or 1.N (Since it can contain 0..N records). Then each Order records will be having one OrderNo, so create a context atttribute(<b>OrderNumber</b>) inside node Order. For each Order(ie. for each Order No.), since there is more than one items, create a node(<b>Items</b>) inside Order with cardinality as false, sothat u will be able to create more than one Items Element for a particular Order element. Inside this Items node, u can create context attributes like <b>ItemsNumber</b>, <b>Price</b>  etc. Then use the code below, which is similar to the code I posted. That code craeates 5 Order records(with order number myorder1,2,etc), with each OrderNo. will be having three Items entries(with itemnumber myitem1,2,3 and Price myPrice1,2,3)
IPrivate<View>.IOrderNode parentNode=wdContext.nodeOrder();
IPrivate<View>.IOrderElement parentEl;
for(int i=0;i<5;i++)
parentEl=parentNode.createOrderElement();
parentNode.addElement(parentEl);
<b>parentEl.setOrderNumber("myorder"(i1));</b>
for(int j=0;j<3;j++)
IPrivate<View>.IItemsNode childNode=parentEl.nodeItems();
IPrivate<View>.IItemsElement childEl=childNode.createItemsElement();
childNode.addElement(childEl);
<b>childEl.setItemsNumber("myitem"(j1));</b>
<b>childEl.setPrice("myPrice"(j1));</b>
