What you Know about EDPOrder ?

Noting ?? no probs..

here is the answer.. .

• An EDPOrder can be seen as a portion of the complete order container. The orders subsystem part is the one that handles order items, taxes, etc. The EDPOrder is the portion that handles the payments part only.
• EDPOrder will provide the status of the task working on a payment action in backgroud
• Copying from another blog
• At the time of adding item to shopping cart ORDERS,ORDERITEMS and EDPORDER will get populate
• Based on the customer payment selection in the order there is a payment instruction record will create in EDPPAYINST
• In the code, EDP Order data is retrieved using the EDPServices as shown below.
•  ---Rest is copyed from chetan;s blog.. here ..
  EDPOrderData edpOrderData = EDPServices.getServices().getOmfAccessor().getOMF().getEDPOrder(new Long(getOrderId()), Integer.valueOf(storeId));
  Long edpOrderId = edpOrderData.getOrderKey();
  
  
  We get the EDP order payment instructions through the following
  
  
  SortedSet pis = EDPServices.getServices().getOmfAccessor().getOMF().getPis(edpOrderId);
  
  
  Using the payment instruction returned, you can get the details like amount, payment method, etc.
  
  
  Orders data can be accessed using the websphere commerce OrderAccessBean and order details using OrderItemAccessBean
  
  
  There is a PPCPAYINST table which stores the value object Payment Instruction in WCS which contains information for payment plugins to process the final payments. Payments for a specific payment method can only be charged upto a maximum specified by the AMOUNT column in PPCPAYINST table. PPCEXTDATA contains non-standard data specific to a payment method. For example, paymentexpress might have some non-standard protocol data which is stored in here
