In the FA disposal, we can see Source Currency Code and Amount dimensions generated in G/L entries.
However, it can only show the total amount of FCY in the entries.
For the source currency amount to show the sales proceeds at the rows of the cost and accumulated depreciation of the asset that was disposed, it creates a discrepancy at the GL accounts of cost and accumulated depreciation between the source currency amount and LCY amount. The feedback is that it would be more useful to users that upon disposal of the FA, the source currency amount is also removed from the cost account, and at the accumulated depreciation row, the source currency amount be zero (ie nil, because depreciation-accumulated depreciation is run at LCY, source currency by design is to show zero).
