single AUC in a project.

Hi All,

In our project we are creating WBSE upto level 3 (at each level there is only one WBSE created). I have assigned investment profile to project definition which is defaulted to WBSEs down the level. .Now , when i am releasing the project three different AUC get created for 1st ,2nd & 3rd level WBSE . But client wants to have just one AUC per project.Because when we do the settlement all the cost get settled to AUC created for 3rd level WBSE and in this case other two AUCs are of no use.

So, kindly let me know how can we have just one AUC created in a project. Client doesn't want to create AUC manually.

Thanks
