Safety stock, forecasting doubts

Question

Can anyone guide me on my doubts,
1) Safety stock : While describing safety stock in oracle, we are mentioning date and quantity. Take a example - item = xyz, Date = 01 Jan 2012, Qty = 10. is it means that 01 Jan 2011 onward, stock level of item xyz should be atleast 10. If it is less that 10 after 10 Jan, then suggest planned order from ASCP.. ?
2.1) I can see that we can manually mention safety stock, system will calculate safety stock. In case of manual, xyz item attribute should be 'Not MRP" Planned. I can mention item, date and qty for in safety stock form.
2.2) In case of system to calculate Safety stock, I have mentioned attribute value as " MRP planned", mentioned safety stock days as well. Here I have created a forecast and ran "Reload safety stocks" with method as "User defined %" with forecast created for SS calculation. Now I can see corresponding newly created SS in system.
Now I have ran data collection with calculate safety stock = Yes, and after than launched plan as well. But I am not able to see both type of safety stock in ASCP workbench. I will say, I am not able to see any safety stock demand in workbench in any one of organization. Like to inform you that while doing collection, I have selected all organizations which are enabled and also same was selected while launching plan.. so whats wrong and so not able to see any safety stock demand in system.
3) Forecasting: I can put forecasting at component instead of products level ( ie finished good). Now suppose, I have kept forecasting at component level, means I have mentioned component item, qty and due date in forecast form. Now ASCP will consider this as demand and drive material, may suggest planned order. Now same time, I have booked a SO, having a products, which requires that forecasted component to do assembly. As there is demand against forecast and demand for SO, will drive material and this will be duplication. So netting of forecast is must, which we can do through forecast consumption. Now in my scenario, I have mentioned forecast for child in forecast and SO is booked against finished item. Now my question is - is there any provision for component level consumption based on finished good SO.. ?
Let me know if anyone needs more clarity on above case,
Thanks and Regards,

Thanks Partha your help. Following solution is working on MRP, but it seems that not working on ASCP. I am pasting process here, Here V is long LT item.
1) Define a planning bill forecast, consider FC00. This contains aggregated demand of V against a particular date.
2) We will explode forecast from FC00 to FC01, where you can see forecast against component of ‘planning bill item’ along with Qty and date. Qty will be derived from planning percentage mentioned in planning bill.
3) In order to convert these forecast demand in purchase order, we have to use a plan.. say ‘Small Plan’. Purpose of this plan is to consider ‘Forecast FC01’ only as demand ( ie do not consider any SO, On-hand etc for calculation ), and create a supply by release planned order. Here needs to run collection and also needs to mention demand schedule as ‘FC01’ in plan parameter.
4) Now all planned order as per forecast will be released and converted either requisition / PO. This may be firm / non firm.
5) Now define another Master plan, ( in order case, this plan will be global plan) which consider all supply and all demand sources. But ensure that we will not mention FC00 / FC01 forecast in this plan demand schedule. This plan will consider PO / requisition supply created via ‘Small Plan’, and will peg to actual SO. This will not peg to FC 01 as we have not attached this forecast to master plan demand schedule.
6) Now if SO dependent demand of V is less than PO qty, then master plan will suggest to raise PO vice versa it will suggest to cancel / re-schedule in –out. We can filter such suggestion by exception / action / supplier name etc. So we will NOT do cancellation / reschedule out, but we will do re-schedule in if possible. This will ensure that we will have enough supply of V irrespective of SO demand.
From above, we can use planning bill as input for long LT items planning and output will purchase order in advance of SO, also consumption ( indirectly) of forecast can happen. If we will mention ‘include past due forecast = 0’ in planning parameter, then automatically past forecast will be excluded from planning.In addition, we can use master plan ‘supply-demand’ workbecnch output for monitering SO demand trend with forecast entry done by planner.
Now am checking on ASCP and believe that it will work in ASCP as well.
Thanks for support ,
