Problem while creating Item Data in OCA application

Question

Hello Experts!
I am creating a PDA application (OCA) for NW7.1.
I am facing problem while creating Sales Order. I can create the Header structure. But when I Create the corresponding item structure for the header , the items are not getting created. After Sync I can only see the header structure in the middleware.
I am using the following code to create the header and item.
OrderCreateDocType header = model.createOrderCreateDocType();
header.setRefdoctype("41001180");
header.setDocType("ZRRJ");
header.setSalesOrg("AND");
wdContext.nodeOrderCreateDocType().bind(Collections.singleton(header));
OcaRoot.getInstance().commit();
wdContext.nodeOrderCreateDocType().setLeadSelection(0);
header=(OrderCreateDocType)wdContext.nodeOrderCreateDocType().getCurrentElement().model();
OrderCreateOrderItemsIn items = header.createNewOrderItemsIns();
long item = new Long("000010").longValue();
items.setItmNumber(item);
items.setMaterial("MMKT090114");
items.setPlant("ANDP");
items.setTargetQty(new BigDecimal(7));
items.setTargetQu("IT");
header.setOrderItemsIns(Collections.singleton(items));
OcaRoot.getInstance().commit();
Am I missing out on step.

Hello Priya
in your case as the DOs are of upload only type, you are not able to create a
child on an already created header, because updates are not allowed for upload only DOs.
So in this case you first have to create an instance of the header first and then create an item. And only after this call a commit on the model
