Accounting Entries required from EAM & Projects as well

HI All,

I've a requirement as below. Could some suggest how to achieve below requirement.

Currently we haven an integration with project costing module with EAM Module. My requirement is like, when we open a job card without project & task reference system should transfer the entries from EAM module to GL (Cost will hit the maintenance dept account from WIP Accounting Class).

In case if I refer any project & task in work order means, system should transfer the WIP Accounting classes entries to Projects, from their it should go to GL. In Project Modules, I want to override the default project segment value with project value with auto accounting rules in projects.
