F42UI11 Update

Hello All,
I need to update the Address Number (AN8) field in the F42UI11 cache/table. Ive tried using BSFN B4201070 Cache, update customer self-service info but i cant get this to update correctly.

Is there another BSFN i can use to do this? Or maybe im not using the BSFN accurately so ive included it below. I have tried passing in other parms but i still cant get it to update.

Thanks in advance for any help, Jeff
