SAP Cloud Application Studio How to retrieve the details based on OVS in Product ID

Question

Hi Experts,
I have small requirements in AdvanceListPanel. I have custom BO as mention below,
businessObject Demo {
               element ID : ID;
               node Sporoduct [0,n] {
                    element P_ID : ProductID;
                    element P_DES :   SHORT_Description;
                    element P_QTY : Quantity;
                    element P_NET :  Amount;   
I have attached the OVS on Product ID (P_ID) element.
I want to auto-fill the details under the AdvanceListPanel ( Product Desc , Product Net value ( Price) ) 
1) How to get the details of Product ( Prod Descr, Product Price etc ).
Please anyone have idea about this share your thoughts.
Many Thanks,
Mithun

Hi, Mithun
     What you want is to auto-fill the related details when you select a product from your OVS.
     That means you have to write your codes in Event After Modify.
     We normally use QueryByElements or some other query options given for a particular standard BO.
     It would be like that.
     var query=Product.QueryByElements;
     var selParams=query.CreateSelectionParams();
     selParams.Add(query.ProductID ,"I","EQ",this.P_ID );
     var result=query.Execute(selParams);
     for(var product in result){
     this.P_DES =product.Description;
What I have just written is just a sample code. You have to find the exact name of the attributes of a standard BO in Repository Explorer.
Hope this helps,
Fred.
