Writeback Timeout Property
This property determines the maximum amount of time (in seconds) the client application will attempt to communicate updates to a writeback table on the server.
When a client application attempts to commit writeback changes to the server, PivotTable® Service begins a count in seconds. The count continues until the commit is successful or the number of seconds specified in this property is reached. If the count reaches the value of this property, the commit fails and the update does not occur. After a timeout failure, the client can roll back the transaction or attempt to commit the transaction again.
This property's value is specified when a session is established, and it cannot be changed during the session.
