The main functionality of the ROLLNAME is to provide a data element that will be responsible for showing F1 help on the grid cell. If in data element the documentation is available, then it will be shown. If not, or if the ROLLNAME will be empty, you’ll receive the message “No documentation available” when you’ll press F1 on a grid cell.

In the demo program I’ve used data element S_CONN_ID to show you how does it work.

On the first sight you can notice that if you’ll use ROLLNAME, then the column description, tooltip and column short and long texts are taken from the data element.

Additionally to this, the main behaviour is also there. F1 shows the documentation from the data element.
