Accounting Entry for Investment tax credit asset.

Hi,

As part of FA implementation, we are testing 'Investment Tax credit' functionality for the assets. but we see that system did not created any accounting entry for the tax credit amount. following is the example.

Asset cost : 1000

Tax credit : 4%

Now the recoverable cost would be = 960 (Asset cost - tax credit:  1000-40=960), no accounting entry was created for the asset cost change.

Please help me to understand on this. am i missing anything here

Thanks

Ramesh
