public function CreateItemHistorySnapshot(
    ItemPath : String, 
    Warnings : Warning[]
) : String

参数

• ItemPath
  类型：System. . :: . .String
  项的完全限定 URL，其中包括文件名（在 SharePoint 模式下，还有扩展名）。

• Warnings
  类型：array<ReportService2010. . :: . .Warning> [] () [] []%
  [out] Warning 对象的数组，它列出在报表处理过程中出现的警告。

返回值

类型：System. . :: . .String
一个表示快照的日期和时间戳的字符串。此字符串用作历史快照的唯一标识符。

注释

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

SOAP Header Usage	(In) TrustedUserHeaderValue (Out) ServerInfoHeaderValue
Native Mode Required Permissions	CreateSnapshot AND Execute
SharePoint Mode Required Permissions	EditListItems()()()() AND ViewListItems()()()()

For the snapshot to be generated successfully, item history must be enabled for the catelog item. To enable item history for a catalog item, use the SetItemHistoryOptions method.

If a report item contains subreports, query result sets from the subreports are persisted in the item history snapshot. Report parameters that are passed to the report at the time the report is executed are also persisted.

Snapshots are created by this method with default parameters only.

The length of the ItemPath parameter cannot exceed 260 characters; otherwise, a SOAP exception is thrown with the error code rsItemLengthExceeded.

The ItemPath parameter cannot be null or empty or contain the following reserved characters: : ? ; @ & = + $ , \ * > < | . ". You can use the forward slash character (/) to separate items in the full path name of the folder, but you cannot use it at the end of the folder name.
