How to Configure FM Spell Amount in Smartforms ?

Hi Gurus / Experts,

this is my first discussion post in 2014, I hope this will become the first answered post too.

I have a requirement to create a smartforms.

In my smartforms I need to use the FM Spell_Amount in Indonesian language, but when I try to call it the Short Dump appear in front of me, the short dump tells us that the 'ID' (Indonesian language format, I set it at tcode oba9) is false. How to fix this ? please correct answer will be rewarded by points.
