Change in Book Control Natural Accounts do not work for existing Assets

 Hi,

Due to business needs, we changed Net Book Value Retired (Gain/Loss) and Reval Reserve Retired (Gain/Loss) natural accounts.

When we did process retiremens for existing assets, NBV Retired still uses old natural account. But if we reinstate this retired asset and again retire it, it takes new natural account.

Can anyone explain why this is happening? And is there a way where we can make the system use new natural accounts without getting into this retire-reinstate-retire cycle?

Thanks,
