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.
