For the many people that have asked this question.
N item category in the BOM is always going to propose direct procurement. Through configuration I have not found a way to make it go away from the planned order. You can make it go away from the production order.
The IMG path: 
Plant Maintenance and Customer Service 
-> Maintenance and Service Processing 
--> Maintenance and Service Orders 
---> Functions and Settings for Order Types 
----> Define Change Docs, Collective Purc. Req. Indicator, Operation No. Interval
Under the Res/PurRq -> Specify Never
In order make this setting effective, you must define the following
system message to error or warning, as it is stated on note 569984
Version Appl.A. No. Cat
00000000 C2 280 W
Please note that this setting is effective for reservations and
requisitions.
The best solution is to use BOM item category L with the bulk indicator set. You will not get any direct procurement proposals or planned orders and you can use long term planning to see the time phased MRP results.
