Disallowance of capital expenditure

Hi All,

Loss on sale of building has been disallowed in computing tax of a company and also reported in tax audit report under Sl.no 1 of clause 21(a) i.e., Capital expenditure. However A.O. raised demand by again adding such amount.

I think i have not shown disallowance under proper column in ITR. Can anyone please suggest in which column of Schedule BP i have to show such disallowance.
