Remarks

Message Availability

For this message to work, the caller must be connected to the server.

Usage

Pass an instance of this class to the Execute method, which will return an instance of DeleteAuditDataResponse.

Privileges and Access Rights

For a list of the privileges required, see DeleteAuditData message privileges.

Notes for Callers

This message behaves slightly different depending on the version of Microsoft SQL Server that is installed on the Microsoft Dynamics 365 server. See Retrieve and delete the history of audited data changes for more information.

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.


// Get the list of audit partitions.
RetrieveAuditPartitionListResponse partitionRequest =
    (RetrieveAuditPartitionListResponse)_service.Execute(new RetrieveAuditPartitionListRequest());
AuditPartitionDetailCollection partitions = partitionRequest.AuditPartitionDetailCollection;

// Create a delete request with an end date earlier than possible.
DeleteAuditDataRequest deleteRequest = new DeleteAuditDataRequest();
deleteRequest.EndDate = new DateTime(2000, 1, 1);

// Check if partitions are not supported as is the case with SQL Server Standard edition.
if (partitions.IsLogicalCollection)
{
    // Delete all audit records created up until now.
    deleteRequest.EndDate = DateTime.Now;
}

// Otherwise, delete all partitions that are older than the current partition.
// Hint: The partitions in the collection are returned in sorted order where the 
// partition with the oldest end date is at index 0.
else
{
    for (int n = partitions.Count - 1; n >= 0; --n)
    {
        if (partitions[n].EndDate <= DateTime.Now &amp;&amp; partitions[n].EndDate > deleteRequest.EndDate)

{
    _service.Execute(deleteRequest);
    Console.WriteLine("Audit records have been deleted.");
}
