I was able to obtain large descriptions for the respective fields in Virtual DataPort server from the JDBC databases automatically while creating a base view.
To add the description of the fields for any particular view, I would follow the below steps:
* Edit the corresponding view by clicking on ‘Edit’ button.
* Click on the pencil icon corresponding to the Description field.
* Either I could edit the description or load a file for the field.
* Finally, save the view for changes to take effect.
The changes made in Virtual DataPort Administration tool will be reflected in the Information Self Service Tool, after performing a refresh.
Whereas it is possible to project only Field Name, Description and Type Name of the fields for a view in Information Self Service Tool.
Hope this helps!
