According to our internal business, we want one of the FD show less FD value for a specific main account type, but whole FD values for other main account type, in the same legal entity, at the same time.

For example, we have 1 account structures, including 2 FD. The 2nd FD should not show "000" FD value in the pull-down list, when the order/journal are using main account (type = P&L). At the same time, in the same legal entity, both 1st and 2nd FD should show all FD values, when the order/journal are using main account (type ≠ P&L).

How to achieve that?
