Disposal of Fixed asset

Dear All,

I Created one Fixed Asset and I posted the acquisition of 1000/- and also posted the depreciation of 500/- in this year.

The total book value of the Asset is 500/-.

Now I want to post the disposal of this Fixed asset. At the time of posting of disposal I am getting the below error.

“Cancel the all depreciation entries for the Asset for the fiscal year before disposal”

Can any one help in this regard.

Regards,

Nanjappa
