Expert mode
If the Expert mode is activated, three additional configuration options are available.
5. In the Expert mode you can define which columns should be managed by the GISconnector.
Press "Next >".
Hint: Generally we recommend to activate respectively let the GISconnector for Excel manage only those columns you intend to transfer in order to maximize speed.
6. Also the transfer parameters can be defined. These can be modified later in the dialogue 
"Edit connection" in the tab Options. With these settings you can control the behaviour of the GISconnector for Excel regarding the creation and deletion of comlumns and rows as well as the management of GCEX_IDs; separately for both transfer directions.
