    Hi,

    I am getting following error frequently in window's Application log from my CRM 2011(RU 14) site. Do you know what is causing this error?

    The Web Service plug-in failed in OrganizationId: XXXXXXXXX; SdkMessageProcessingStepId: XXXXXXX; EntityName: serviceappointment; Stage: 30; MessageName: Book; AssemblyName: Microsoft.Crm.Extensibility.InternalOperationPlugin, Microsoft.Crm.ObjectModel, Version=5.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxx; ClassName: Microsoft.Crm.Extensibility.InternalOperationPlugin;

    The method that throws the error relates to scheduling appointments or service activities. One possible cause is if you have an appointment or service activity (or maybe related data like resources) that are missing some require fields.
