Ad Hoc Estimate in cProjects

Question

Hello everybody,
Reading the SAP help on the topic my understanding is that one can execute ECP for a cProjects before an acount assignment exists for that project. Do I understand it coorectly? If Yes, then how do I get the "AD HOC ESTIMATE" button or link activated.
As of now I can only see change Easy Cost Planning object link for a WBS (under Services) only after I have assigned the PS Project to my cProject.
I maintained a costing variant for ECP Ad Hoc Estimate - in the ERP system under "Settings for Easy Cost Planning".
Here is what SAP help says:
"You are on the Accounting tab page, have costed the simulation or project (Cost button) and saved it.
__Choose Ad Hoc Cost Estimate.__The Change <name of project>: Easy Cost Planning screen appears."
Thank you,
Lacramioara

This solved my problem; The formatting is lost, but basically it says you need to configure the ECP costing variant using PADH not PS06....I hope it helps!

Define Costing Variant- Ad Hoc Cost Estimate
Use
The costing variant in this Config. Guide is used for Easy Cost Planning that will be used to create the basis for a quotation created by using sales pricing. 
In Easy Cost Planning, the costing variant determines the following:
The Purpose of the cost estimate (Costing type)
The prices that are selected to valuate the costing items (valuation variant)
For internal orders, work breakdown structure elements, and ad hoc cost estimates, the dates that apply to the cost estimate (date control)
