CJ20N special stock reservations problem

Hello there,

I have the following issue: I want to add materials in CJ20N (in component overview) under a certain activity, and I would like the system to generate reservations for the upper WBS element, and not for the upper network. Infact it does that by setting Valuated stock or Nonvaluated stock in Control data tab of the project, but my problem is that every material that I entered has the special stock "Q" set. Is there any way that I could generate reservations for the WBS element without the special stock set ?

I have attached a printscreen image of CJ20N transaction with the items enteres in component overview.

Help will be appreciated.

Thanks,

Adi M.
