Commitments in network

Question

Hi Gurus,
We have defined a Order Type that is a Network (has been defined with Order category 20). Whe assign some Networks  to a WBS Element.
When we make a purchase requisiton to a WBS Element we can see in the transaction S_ALR_87013542 - By Cost Element -> Actual/Commitment/Total/Plan in CO Area Currency that the commitment appear, however when we make a PO to the same WBS Element, the commitment does not appear. The cost appears then when we execute theMIGO, it appears as actual cost
I have chequed the customizing of the WBS Element and I can't see where active the commitment management for WBS Element. In the OKKP the commitment management  and Projects are active, why we can't see the commitments when we make the PO?
I have seen as well that in Tcode KOAO the Order category that are 20 ( Network ) do not have the flag to activate the commitment mamagement, does it have something to do with out problem?, because when we make the purchase requisiton to a WBS Element, we can see the commitment...
Thank you veru much

Dear all,
I have run the transaction CJEN and appear the message:  u201CNo value category could be determined for cost elementu201D.
Does it has something to do with the fact that commitments are not appearing?. I have done some test using report S_ALR_87013542, and here are the results:
u2022     If we create a Material Purchase Requisition the commitment do not appear in the report.
u2022     If we create a Material Purchase Order the commitment do not appear in the report.
u2022     If we do the post of a material PO  (Tcode MIGO)  the actual cost appears in the report.
u2022     If we create a Purchase Requisition for an Ext. Processing Activity the commitment appears in the report.
u2022     If we create a Purchase Order for an Ext. Processing Activity the commitment is updated in the report.
u2022     If we enter the invoice of the Purchase Order for an Ext. Processing Activity (Tcode MIRO)  actual cost does not appear in the report.
Could be a G/L Account determination problem?
Could anyone lend a hand?
Thank you very much
