Update rule mapping in SWM 6.2 app

Hi All,

I am customizing the SWM 6.2 work orders list screen with additional fields, but I have an issue while updating data into the fields.

I have 3 objects Obj1, Obj2 & Obj3.

Obj1(Main Object), Obj2(Work Order) is collection obj1 & obj3 (Equipment / Functional Location) is collection obj2.

My screen set was defined for obj1 and list tile view screens in screen set were defined for obj2 and in the list tile I want to display the properties of obj3 in list tile view screens.

Please suggest on how to map the update rule to display the data. I have tried the rule as below.

OBJ2 object-->obj3 collection-->First object in collection-->Obj3 property.

This was not displayed any value in the screen.

Thanks & Regards,

Roopa M.
