Clearing negative balance of an CIP asset

Hi Experts

Can anybody help me understanding why the below situations occurs:

I have an Internal order (Capitalized IO) whose CIP asset is showing a balance of -0.90 in AS03. But when I pull the KOB1 report it shows 50000 or display the Budget/Actual/Commitment report it showing a value for  50000 in the Actual Column.Why is it so?

The IO is capitalized to more than 25 assets and some assets are disposed also. In this case I am also not able to settle the -0.90 to the final assets. Is there any way to clear this -0.90 and finally to close the IO.?

Thanks & Regards
