Safety Stock Not Being Released To Cover New Sales Orders Or Forecast

Question

Hi,
Does anyone know of a way to get safety stock at the lower levels of the BOM to get released for upper level sales order or forecast demand without having to adjust the effectively out to a future date?
Example:
A = Finish goods item with two weeks lead time
B= component of A and it has two weeks lead time
C= component of B and has 10 weeks lead time.
Have safety stock hard coded with an effective date of today for 100,000 units.
I have 100,000 in inventory and I have planned orders to cover all my demands and future safety stock requirements for the next ten weeks.
I receive a new sales order for 50,000 units with a customer request date five weeks out.
I am getting ATP dates to assign to the new sales order 14 weeks out versus allowing me to use 50,000 units from the safety stock to schedule in week five?
Even If I schedule the sales order for five weeks, because I have gone down two levels to confirm that I have safety stock, and It could be used, planned orders would not get generated at the next two levels, because the demand date on the safety stock is earlier than the demand date for the new order?
Is there any resolution that anyone has found that addresses this issue?
We have set a demand priority rule on the ASCP plan options tab to "Sales Order Priority" where we have set criteria for number one to "Sales Orders & MDS Entries Priority" and number two to "Schedule Date".
We have found that adjusting the supply and demand dates out to cover the full 14 week period does reduce the safety stock at the lower levels, but it also creates additional starts and inventory to be put into the line, which makes this approach not feasible.
Does anyone have any solutions to this problem? We do not build safety stock for the sake of building safety stock. We want it to be used for any sales order or forecast demand that comes within the planning horizon.
Appreciate any inputs.
Regards,
Dave

Hi Dave,
Try this note suggestion, possibly help you in resolving your issue.
How to Avoid Getting Safety Stock Replenishment Too Early in an ASCP Plan [ID 301629.1]
In order to line up the safety stock supply with the changes in safety stock, a combination of the profiles must be used:
MSC: Use FIFO Pegging as yes
and the plan option
Peg Supplies by Demand Priority is checked.
The profile MSC: Use FIFO Pegging as yes will perform the following:
For all demands and supplies, it proceeds item by item and
pegs supplies to demands on a daily basis. Daily supplies
and demands are not sorted. When supplies or demands
on a given date are used up, it picks from supplies or
demands on the next date. The unpegged supplies are
pegged to excess.
The peg supplies by demand priority combined with the profile above will prevent the system to plan ahead for safety stock.
Also no safety stock smoothing is setup.
To implement the solution, please execute the following steps:
1. Please set the profile:
MSC: Use FIFO Pegging as yes and
2. Under the plan settings in the main tab the set the following options:
Enable Pegging ON
Peg Supplies by Demand Priority ON
