Hi Faisal,
In order to achieve the above mentioned functionality , you will have to create UI object types first. Supose you have 3 process types , then first create 3 UI object types ( Name and description ). Then for each new config assign Sub-object type (UI object). Then in DO_CONFIG_DETERMINATION you can use CASE statement to load the respective configuration using object type and Sub-object type. Hope it helps.
