Sample: Clean up history for a queue (early bound)
Applies To: Dynamics CRM 2013
This sample code is for Microsoft Dynamics CRM 2013 and Microsoft Dynamics CRM Online. Download the Microsoft Dynamics CRM SDK package. It can be found in the following location in the download package:
SampleCode\CS\BusinessDataModel\BusinessManagement\CleanUpQueueItems.cs
SampleCode\VB\BusinessDataModel\BusinessManagement\CleanUpQueueItems.vb
Note
This sample for the Queue entity was not updated for changes introduced with Microsoft Dynamics CRM 2013 Service Pack 1 (SP1) and Microsoft Dynamics CRM Online Spring ‘14. While it continues to work, it doesn’t represent the best practices to use with queues in the most recent release. More information: Enhancements to queues with Microsoft Dynamics CRM 2013 service pack 1 (on-premises) and Microsoft Dynamics CRM Online Spring ‘14
Rather than deleting queue items, you can use the RemoveFromQueueRequest.
Requirements
For more information about the requirements for running the sample code provided in this SDK, see Use the sample and helper code.
Demonstrates
This sample shows how to clean up the history for the queue by deleting inactive items. It finds completed phone calls in the queue and deletes the associated queue items. Note that the completed phone calls are not deleted by this action.
