The WebUI dialog-window for choosing an alternate delivery address doesn’t allow us to have a look at the technical details. So it is hard to find out which component is responsible for the configuration of that dialog.
The component „GS_SIMPLE_ADDR“ is responsible for the configuration of that dialog window with its views like “POSTALVIEW”.
Besides being used for the alternative shipping address, the component is also used in the view for involved companies within the opportunity-management.
Before customizing the component it should be copied to avoid interference with other system functions.
