Remarks

Message Availability

This message works regardless whether the caller is connected to the server or offline.

Usage

Pass an instance of this class to the Execute method, which returns an instance of DeleteOpenInstancesResponse.

Privileges and Access Rights

To perform this action, the caller must have privileges on the entity specified in the Target property and access rights on the record specified in the Target property. For a list of the privileges required, see DeleteOpenInstances message privileges.

Notes for Callers

Using this message does the following:

Deletes all the “open” and “scheduled” future instances of the specified series from the date specified in the SeriesEndDate property. However, if the state of the future instances is changed to “completed” or “canceled”, they are not deleted.
Sets the status of the past instances to the specified value in the StateOfPastInstances property. However, the past instances are not deleted.
Terminates the series to the last occurring past instance date with respect to the date specified in the SeriesEndDate property, and sets the state of the series to “canceled”.

This allows you to preserve the instances of a recurring appointment series even if you have decided to end it prematurely. This is useful if you have attached notes or attachments to past instances of a recurring appointment series that contain important information about the customer or business.

Examples

The following example shows how to use this message. For this sample to work correctly, you must be connected to the server to get an IOrganizationService interface. For the complete sample, see the link later in this topic.



// Retrieve a recurring appointment series
RecurringAppointmentMaster retrievedRecurringAppointmentSeries = (RecurringAppointmentMaster)_serviceProxy.Retrieve(RecurringAppointmentMaster.EntityLogicalName, _recurringAppointmentMasterId, new ColumnSet(true));

// Use the DeleteOpenInstances message to end the series to the
// last occurring past instance date w.r.t. the series end date
// (i.e., 20 days from today). Effectively, that means that the 
// series will end after the third instance (day 14) as this
// instance is the last occuring past instance w.r.t the specified 
// series end date (20 days from today).
// Also specify that the state of past instances (w.r.t. the series 
// end date) be set to 'completed'.
DeleteOpenInstancesRequest endAppointmentSeries = new DeleteOpenInstancesRequest
{
    Target = retrievedRecurringAppointmentSeries,
    SeriesEndDate = DateTime.Today.AddDays(20),
    StateOfPastInstances = (int)AppointmentState.Completed
};
_serviceProxy.Execute(endAppointmentSeries);

Console.WriteLine("The recurring appointment series has been ended after the third occurrence.");



' Retrieve a recurring appointment series
Dim retrievedRecurringAppointmentSeries As RecurringAppointmentMaster = _
    CType(_serviceProxy.Retrieve(RecurringAppointmentMaster.EntityLogicalName, _recurringAppointmentMasterId, _
                                 New ColumnSet(True)), RecurringAppointmentMaster)

' Use the DeleteOpenInstances message to end the series to the
' last occurring past instance date w.r.t. the series end date
' (i.e., 20 days from today). Effectively, that means that the 
' series will end after the third instance (day 14) as this

' series end date (20 days from today).
' Also specify that the state of past instances (w.r.t. the series 
' end date) be set to 'completed'.
Dim endAppointmentSeries As DeleteOpenInstancesRequest = New DeleteOpenInstancesRequest With { _
    .Target = retrievedRecurringAppointmentSeries, .SeriesEndDate = Date.Today.AddDays(20), _
    .StateOfPastInstances = CInt(Fix(AppointmentState.Completed))}
_serviceProxy.Execute(endAppointmentSeries)

Console.WriteLine("The recurring appointment series has been ended after the third occurrence.")
