Hi,
I will find hard to help you I'm afraid, because we are not using FI on the system I'm supporting (it's an industry solution IS-U/CCS), nothing seems to be customized, and I have not managed even to identify the dynpro you/the SAP Note are talking about 
If you could give me some technical info like screen and program name, I could try more, but I'm not very hopeful at the moment. Is that screen for some localization for India only, perhaps? If so, it's basically hopeless for me to even try.
cheers
