Internal Project Settlement

Hi Guys,

I've one query in settlement of internal project.

I want to settle actual cost occured on child WBS to header WBS which are on different level. As my structure is very huge I can not maintain settlement rule on all WBS element as well as I do not want to pass on header WBS settlement rule to lower WBS which will increase no of line items during settlement for project. I am not able to do so.

Can some one help me how to settle lower WBS cost to header WBS.

Regards

Gaurav
