In the CRM webclient, the properties of a field can be changed.
The change can vary from changing the field type, for instance changing a dropdown listbox to an ordinary input field or a checkbox or a radiobutton, to changing the tooltip text, to implementing navigation to another screen when clicking on the field.
The changes are done in the GET_P of an attribute of the context node.

rv_value = cl_bsp_dlc_view_descriptor=>field_type_event_link. WHEN
rv_value = ‘NAVIGATE_TO_TARGET’.ENDCASE

Changing a field to a checkbox and adding a tooltip.
rv_value = cl_bsp_dlc_view_descriptor=>field_type_checkbox.
rv_value = text-001.
One of the importing parameters of the get_p is the field IV_DISPLAY_MODE. This field can be checked to see whether the field is in change or in display mode. You can implement different properties to the field in change and in display mode.
Another of the importing parameters is the IV_INDEX. This can be used to determine in which line you are in the table.
