[SOLVED] CRM 2011 SDK transaction

CRM 2011 SDK transaction

How to create transaction using crm 2011 sdk and XrmServiceContext?

In next example 'new_brand' is some custom entity. I want to create three brands. Third has wrong OwnerID guid. When I call SaveChanges() method, two brands are created and I've got exception. How to rollback creating of first two brands?

Is it possible without using pluggins and workflows?

using (var context = new XrmServiceContext(connection))
{
    SystemUser owner = context.SystemUserSet.FirstOrDefault(s => s.Id == new Guid("XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"));

    // create 3 brands
    new_brand b1 = new new_brand();
    b1.new_brandidentification = 200;
    b1.new_name = "BRAND 200";
    b1.OwnerId = owner.ToEntityReference();
    context.AddObject(b1);

    new_brand b2 = new new_brand();
    b2.new_brandidentification = 300;
    b2.new_name = "BRAND 300";
    b2.OwnerId = owner.ToEntityReference();
    context.AddObject(b2);

    new_brand b3 = new new_brand();
    b3.new_brandidentification = 400;
    b3.new_name = "BRAND 400";
    b3.OwnerId = new EntityReference(SystemUser.EntityLogicalName, new Guid("00000000-0000-0000-0000-000000000000"));
    context.AddObject(b3);

    context.SaveChanges();
}

Solution

Is it possible without using plugins and workflows?

No I don't believe that it is. Each context.AddObject() is atomic. If you don't want to use plug-ins then all I think you can do is have some sort of clean-up logic that deletes the created records if your conditions are not met.
