Error on estimate posting of Investment project

In Ax 2009, I have created an investement project and posted few expense transactions against that project. I’m using balance sheet account for recording expenses. Now I want to move these balance sheet balances to a fixed asset and for that when try to post estimate for this project, I’m getting this error…

Account number for transaction type Project - WIP cost does not exist.”

The account has been setup for project group but still I’m confused why Im getting this error. Is there any other place where I need to setup this.

Thanks.

The problem resolved after I enable configuration key of Hours under Project. Some debugging has led me to this solution. For me, enum type ProjLedgerStatus should not have config key of ProjBasicHour.
