Deactivate Subscription Service

The following example shows the deactivation of a subscription service given that you already have the installed items and the services on the subscription.
You have to retrieve all provisioning distributors that the installed item is distributed on, and then for each one, find the distributed services and deactivate them.
deactivateService.java
@EJB private CRMProcessSubscriptionServiceDeactivationBean processSubscriptionServiceDeactivationBean;    
public CRMDOSubscriptionAction deactivateService(CRMDOSubscription subscription,CRMDOInstalledItem installedItem){
    
    ArrayList<CRMDOSubscriptionService> servicesToBeDeactivated = new ArrayList<CRMDOSubscriptionService>();
    
    //create the subscription service deactivation data object
    SubscriptionServiceDeactivation subscriptionServiceDeactivation = processSubscriptionServiceDeactivationBean.constructSubscriptionServiceDeactivation(subscription);
    //the list of products that will be deactivated
    //in this example the product that will be deactivated will be retrieve based on the installed item
    Set<SubscriptionActionProduct> servicesToBeProcessed = new HashSet<SubscriptionActionProduct>();
    
    //retrieve the subscription installed item.
    CRMDOSubscriptionInstalledItem subscriptionInstalledItem = (CRMDOSubscriptionInstalledItem)subscriptionInstalledItemBean.load(subscription, installedItem);
    
    //retrieve the related distributions of the installed item
    ArrayList<CRMDO> installedItemDistributions = subProvisioningDistributionBean.load(subscriptionInstalledItem);
    
    //retrieve all the service distributions 
    ArrayList<CRMDO> serviceDistributions = subProvisioningDistributionBean.loadServiceDistributions(subscription, null);
    
    //retrieve all the subscription services distributed on the same distributor as the installed item
    for (int i=0;i<installedItemDistributions.size();i++)
    {
        CRMDOSubProvisioningDistribution installedItemDistribution = (CRMDOSubProvisioningDistribution)installedItemDistributions.get(i);

            {
