Demand for Phantom parts ?

Question

We have a BOM, where parent part (say 'A') is defined 'Phantom' item. And this is the topmost part and this BOM is not part of any other BOM. My question is, will ASCP generate demand for component defined under part 'A' ? We are not seeing any demand for components. I believe that if topmost parent is Phantom, no demand will be generated for any of the child. Please let me know any inputs. Thanks.

Hi Gaurav
Let me give you further detail to explain the problem.
Child part - A
Parent part - B
Finished Product - C
Step 1 - We purchase part "A".
Step 2 - We supply part "A" to subcontractor supplier,
              who after processing part "A" supplies back to us part "B".
Step 3 - We issue part "B" to finished product "C" ,as part "B" is a BOM component for part "C"
The problem we face is that when Demand for part "C" comes through, it in turn places Dependant Demand on BOM compnent part "B".
The APO SNP system then raises Purchase Reqs for part "B" which is placed on our Subcontractor supplier.
However the demand for part "B" is not distributed to part "A" which we need to raise Purchase Reqs for as it is needed to be supplied to Subcontractor to process for us and then in turn supply back to us part "B".
Please advise as to how we can distribute the demand for part "B" to part "A" as there is a 1 to 1 ratio, so for every 1 part "A" we purchase and supply to Subcontractor, we raise a Purchase Req against the Subcontractor to receive back 1 part "B" which we issue to Production order for finished part "C".
Also please let me know what the settings in the R/3 material masters should be for part "A"and "B" on tabs MRP 1, 2, 3 and 4
Please let me know if there is any other info you require from me, to assist me.
Thanx in advance
