Hinweise

The table below shows header and permissions information on this operation.

SOAP Headers	(Out) ServerInfoHeaderValue
Required Permissions	The user must be a database administrator or the one configured as the unattended execution account. For more information, see Ausführungskonto.

The ID returned by the CreateBatch method is used to group or batch subsequent Web service method calls. Each method included in the batch must have the batch ID specified in the SOAP header. To batch the method calls using the Microsoft .NET Framework, you must first set the BatchHeaderValue property of the Report Server Web service proxy class to a value that is equal to that of a BatchHeader object that contains a previously created batch ID.

Beispiele

To compile this code example, you must reference the Reporting Services WSDL and import certain namespaces. For more information, see Compiling and Running Code Examples. The following code example creates batch IDs for two new batches of Web service method calls and executes the batches:

Class Sample
   Public Shared Sub Main()
      Dim rs As New ReportingService2005()
      rs.Credentials = System.Net.CredentialCache.DefaultCredentials

      Dim bh1 As New BatchHeader()
      Dim bh2 As New BatchHeader()

      bh1.BatchID = rs.CreateBatch()
      rs.BatchHeaderValue = bh1
      rs.CreateFolder("New Folder1", "/", Nothing)
      rs.CreateFolder("New Folder2", "/", Nothing)
      rs.CreateFolder("New Folder3", "/", Nothing)

      bh2.BatchID = rs.CreateBatch()
      rs.BatchHeaderValue = bh2
      rs.DeleteItem("/New Folder1")
      rs.DeleteItem("/New Folder2")
      rs.DeleteItem("/New Folder3")

      rs.BatchHeaderValue = bh1

      ' Create folders using a batch header 1.
      Try
