Example using proxy classes:

open fun applyChangesExample(): kotlin.Unit
{
    val service = this.service;
    val suppliers = service.getSuppliers(DataQuery().top(2));
    val products = service.getProducts(DataQuery().top(3));
    val product1 = products[0].copy();
    val product2 = products[1].copy();
    val product3 = products[2].copy();
    product1.productName = "Blueberry Muffins";
    product2.productName = "Strawberry Yoghurt";
    product3.productName = "Raspberry Pie";
    val entityCreates = ChangeSet();
    entityCreates.createEntity(product1);
    entityCreates.createEntity(product2);
    entityCreates.createEntity(product3);
    service.applyChanges(entityCreates);
    val entityChanges = ChangeSet();
    product2.productName = "Blackberry Yoghurt";
    entityChanges.updateEntity(product2);
    entityChanges.deleteEntity(product3);
    service.applyChanges(entityChanges);
    val linkChanges = ChangeSet();
    val supplier1 = suppliers[0];
    val supplier2 = suppliers[1];
    linkChanges.createLink(product1, Product.supplier, supplier1);
    linkChanges.updateLink(product1, Product.supplier, supplier2);
    linkChanges.deleteLink(product1, Product.supplier);
    service.applyChanges(linkChanges);
}

Example using dynamic API:

open fun applyChangesExample(): kotlin.Unit
{
    val service = this.service;
    val suppliersEntitySet = service.getEntitySet("Suppliers");
    val productsEntitySet = service.getEntitySet("Products");
    val productEntityType = productsEntitySet.entityType;
    val productNameProperty = productEntityType.getProperty("ProductName");
    val supplierProperty = productEntityType.getProperty("Supplier");
    val suppliers = service.executeQuery(DataQuery().from(suppliersEntitySet)
        .top(2))
        .getEntityList();
    val products = service.executeQuery(DataQuery().from(productsEntitySet)
        .top(3))
        .getEntityList();
    val product1 = products[0].copyEntity();
    val product2 = products[1].copyEntity();
    val product3 = products[1].copyEntity();
    productNameProperty.setString(product1, "Blueberry Yoghurt");
    productNameProperty.setString(product2, "Strawberry Yoghurt");
    productNameProperty.setString(product3, "Raspberry Pie");
    val entityCreates = ChangeSet();
    entityCreates.createEntity(product1);
    entityCreates.createEntity(product2);
    entityCreates.createEntity(product3);
    service.applyChanges(entityCreates);
    val entityChanges = ChangeSet();
    productNameProperty.setString(product2, "Blackberry Yoghurt");
    entityChanges.updateEntity(product2);
    entityChanges.deleteEntity(product3);
    service.applyChanges(entityChanges);
    val linkChanges = ChangeSet();
    val supplier1 = suppliers[0];
    val supplier2 = suppliers[1];
    linkChanges.createLink(product1, supplierProperty, supplier1);
    linkChanges.updateLink(product1, supplierProperty, supplier2);
    linkChanges.deleteLink(product1, supplierProperty);
    service.applyChanges(linkChanges);
}

Example using proxy classes:

open fun joinTransactionExample(patient: Patient): kotlin.Unit
{
    val service = this.healthService;
    val changes = ChangeSet();
    val appointment1 = Appointment();
    changes.createEntity(patient);
    changes.createRelatedEntity(appointment1, patient, Patient.appointments);
    service.applyChanges(changes);
    // Some time later... Attach another appointment to the same transaction as the patient.
    val appointment2 = Appointment();
    changes.createRelatedEntity(appointment2, patient, Patient.appointments,
        com.sap.cloud.mobile.kotlin.odata.http.HttpHeaders.empty, RequestOptions()
        .joinTransaction(patient));
    // Some time later... Upload the patient and both appointments in the same backend transaction.
    service.upload();
