Parameter and Command Reference > Connector Framework Server Parameters > Import Tasks and their Parameters > UpdateN

UpdateN is used to specify tasks that are called when CFS is about to update fields in a document in IDOL Server. This is when a connector updates the metadata for a document but not the content. Tasks must be numbered starting from zero (0).
The import tasks that can be called by UpdateN are IdxWriter and Lua.
In the example below, Update0 runs a Lua script when a document is about to be updated.
