To execute delete operations on an MBO, get an instance of the MBO, set the MBO attributes, then call the delete() operation.
Customer cust = Customer.findById(101); cust.delete();
For MBOs in a relationship, perform a delete as follows:
Customer cust = Customer.findById(101);
com.sybase.collections.ObjectList orders = cust.getSalesOrders();
SalesOrder order = (SalesOrder)orders.getByIndex(0);
order.delete();
cust.submitPending();
