Hi,

i want to develop web service class which is take opportunity id and List of products as input.

from that list of products i have to create opportunity products.

for this requirement i have to take care the following actions

a)avoid duplicates of products(i have to check the incomming products with existing products based on some fields like Productid__c,if it is exist its updated if it is not dere insert and finally add to opportunity products)

b)used to Standard pricebook id

c)create pricebook entry

d)OpportunityLineItem

please suggest me how i achieve this functionality......


global class BB_productservicenew{

    // A class to accept an array of input records (e.g. product/amount combinations)
    global class productInfo{
        webservice String productName;
        webservice String productCode;
        webservice Double UnitPrice;
        webservice Double Quantity;

      
    }
   
    // A class to send back as an output to PHP
    global class myOutputs{
        webservice String errorMessage;
        webservice Boolean success;
        webservice List<productInfo> inputs;
        webservice Id OpportunityId;
    }

webservice static myOutputs initiateService(Id OppId, List<productInfo> inputs)
 
    {
     List<String>pidlist=new List<String>();
     for(BB_productservicenew.productInfo ps:inputs)
     {
       pidlist.add(ps.productCode);
   
     }
    
        List<Product2>plist2=[select id,name,productCode,ProductId__c from Product2];

        for(Product2 pd:plist2){
      
         for(Integer i=0;i<inputs.size();i++){

                  Pd.Name=inputs[i].productName;
