I have a Bill of material ,the structure listed as below:
A(semi finished goods,F,30)
B (trading goods,F),below the A
C(phantom part,E+50),below the A
E(trading goods,F),below the C
F(trading goods,F) ,below the C
Now I want to get the A from vendor after I send E,F to him,and B is provided by vendor himself .and in sap ,I need system generate PR (purchase requirement)for A,E,and F
but no PO(planned order) generated for C,no PR for B
Now system shows to me:
1. I have given the "Y" of Item category to C and have defined C as E50(Procurement typeSpecial procurement),but still have PO generated.
2. A PR generated for B,but I need SAP ignore it,because vendor will buy it by themselves.
I think this is something like assembly subcontracting,but I am not sure is it same or not
Any advices are welcome!
