Copy item from List A to List B, generate 2 rows in List B

Question

Hi, 
I would like to copy and update items from List A to List B. However, I want the item to be duplicated in List B.
I will explain my scenario
- List A contains a People Picker column of multiple selection and a Title column
- When the form is submitted, a workflow should trigger to copy the item to List B. If the People Picker column contains 2 values inside it, for example, user1;user2. The copied item should be duplicated in rows according to the number of users.
Example
Columns   Title, Users, ID
List A - TicketNo1, User1; User2, 1
List B - TicketNo1, User1              1
List B - TicketNo1, User2              1
Can this be done OOTB or must we use some event receiver..has anyone ever done such a thing before?

Hi,
Below code help you to accomplish your task using event receiver
public
override void ItemAdded(SPItemEventProperties properties)
//base.ItemAdded(properties);
if (properties.ListTitle ==
"ListA")
SPUser user = null;
//get value of fields
string strTitle = Convert.ToString(properties.ListItem["Title"]);
SPFieldUser userField = (SPFieldUser)properties.ListItem.Fields.GetField("TaskAssignUser");
SPFieldUserValueCollection fieldcollectionValue = (SPFieldUserValueCollection)userField.GetFieldValue(Convert.ToString(properties.ListItem["TaskAssignUser"]));
foreach (SPFieldUserValue fieldValue
in fieldcollectionValue)
                   user = fieldValue.User;
                   //Create items in another list
SPList destinationList = properties.Web.Lists["ListB"];
SPListItem targetItem = destinationList.Items.Add();
                   targetItem["Title"] = strTitle;
                   targetItem["WorkAssigned"] = user;
                   targetItem.Update();
Thank You,
