Collective Production Order for ITEM hierarchy

Hello All,

I have a Sales Order , with ITEM 10 XYZ (which is text material (does not have MRP views))

Below it ihave 2 items

20 pqr

30 abc

Both are assigned as SUB items to higher level item 10.

Part 2.

I now try to create a Production Order (co07),

When we create a PO for a Given Sales Order it normally

expands teh BOm item and creates a network of PO for Sub items. (Also allocating the Lead PO number under assignment Tab for child items).

Unfortunely in this case it does not behave like that , as it is not a BOM item (i.e 10).

If i want the same behaviour even in this case what all i need to do ..

F1 Please!!
