Hi Johnson,
You need to make changes in the configuration in the warranty claim layout, where in the item tab assign the screen S2280 or S2285, then you will have the option to enter the measurement details & unit of reading.
These are standard screen, in case these do not work, you might have to create custom screens with the same layout & build the logic of saving the item measurement reading by implementing BADI WTY_CREATE_COPY
