Capture Planned depreciation on Negative Value in its whole Life.

Hello Experts,

I want to capture negative asset acqisition value in asset accounting and further want to capture its month wise planned depreciation value.

I create a new transaction type by copying standard asset transaction 100 and change its transaction group to 11and mark the same as credit transaction. further i create a new dep area with no postings and restrict this transaction type to that dep area.

By this i am able to post negative acquisition value in asset through abzon but system is showing 100 % depreciation in the month of acquisition only but not on the basis of life. I want to capture planned depreciation on this negative value in its whole life.
