So here we have the search and list UIBB are integrated in an OVP application. On search it displays some records.
If you put the cursor point of CARRID field it should display the tooltip text as the CARRNAME.
For the list we have the table type and the structure.
The structure includes both CARRID and CARRNAME field.
In the feeder class method GET_DEFINITION of the LIST UIBB, we have to set CARRNAME field as the TOOLTIP reference of the CARRID field.
Here we have the select query that gets the value when SEARCH is pressed.
