Accounting based on Project Status

Hi All,

We have a requirement of accounting cost transactions based on project status. There are statuses i.e. Pre-Contract and Approved.

When project status is Pre-Contract then all types costs should go to deferred accounts. When the status of the project is changed to Approved then cost should be transferred from deferred account to Actual Cost account.

This Cost transfer from Deferred to Actual cost accounts has nothing to do with revenue.

Need to your inputs/solution to address this requirement. 

My views:

1. We need to configure AutoAccounting Rules based on Project Status. It will be SQL Statement types of rules. Also for Supplier/iExp/PO we need to customize the account generator to build charge account based on Project Status.
