Error at the time of Sales Pricing.

Question

Hi All,
My WBS is :
Level 1      PS.001
Level 2      PS.001.1 &  PS.001.2
I am doing unit costing through CJ40 where i select wbse PS.001.1(supply of materials) and  plan the cost for different materials going to be used in the project. Similarly i select PS.001.2 ( Erection work) and do the cost planning for services. Now i create an inquiry where i assign the top level wbse i.e PS.001 to inquiry item and also assign the DIP profile to both inquiry and project. Now, when i put top level WBS element PS.001 on selection screen of DP81,system gives an error "NO expenditure item found". But at the sametime if in place of PS.001  i assign to inquiry PS.001.1 or PS.001.2 and  put PS.001.1 or PS.001.2 on selection screen, system doesn't give any error.
So, i just want to know that whether system is behaving correctly ?. Because what i have learnt from different documents and sources we always assign the top level wbse to inquiry item.
Thanks.

Hi,
It is not necessary to attach only the top level WBSE.
Conceptually the WBSE which carries the cost plan / which is responsible for execution .... should be responsible for the delivery & billing & to carry revenue.
