Plannin g with forecast as well as safety stock

Hi,
I have one requirement, for the finish product we use the Forecast based planning, in this case if we mantain the forecast for particular month as 100 then system will only plan the materal for the 100 quanity, but our user requirement is we will keep the forecast qty. as 100 but is if sales order qty is more than forecast then system should add that qty. in the planning
Forecast : 100
Sales order : 150,
then system should the the material planning of 150 insted of 100. is it possible.
regards,
zafar

Dear,
What is your MRP type?
If you are using V1 or V2 then you can use the Include ext. reqmts in configuration of MRP type in OMDQ
If VV then use the Calculate safety stock' indicator is set for MRP type In OMDQ.
Else SAP enhancement MM61W001go to Transaction SMOD for this and read document and OSS Note 351240

Forecast execution is resetting safety stock

I have MRP set up for CBP (VV MRP Type). I maintain a static safety stock value. When I run my forecast, without changing the forecast model or any other forecast values, the system resets the safety stock to zero. I'm struggling to figure out what is causing this. Just a stab in the dark, but can the 'reset automatically' flag have something to do with this behavior?
Thanks, Vlad

Safety stock, forecasting doubts

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,
Dipak

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 ,

Minimum safety stock

Hi,
I maintained minimum safety stock as-50 in MRP2 view while creating material master, my client requirement is this minimum safety stock should not be issued at any cost, without enhancement from abap consultant i need to maintain this safety stock.
can anyone help me to cose this issue.

Hi,
Minimum Safety Stock
The quantity that defines the lower limit for safety stock. This value cannot be exceeded.
Use
Defining a lower limit can influence the following:
material master data maintenance
The safety is checked to see if it is greater or equal to this lower limit.
forecasting
The lower limit is checked if you use an availability indicator which shows, according to customizing settings, if the safety stock is to be calculated again in a forecast.
If the safety stock is lower than this level in forecasting, the safety stock is automatically increased to the value of the lower level.
Dependencies
The safety stock must always be greater or equal to this lower level.
Hope this helps.
Revert if you need more details.

Safety stock and min safety stock

Dear all,
CAn anybody explain me the functional difference between safety stock and min safety stock?
And what is the meanng of safety time?
Karthick

Hi,
Safety Stock:
The quantity of stock to satisfy high requirements. The purpose of the safety stock is to prevent material shortage.
Safety stock as the name suggest is the stock level till which the dead stock or stock out situation will not arise (probable figure based on past data maintained in master).
As such this figure is not stock, it is cut-off figure maintained in master which is used for Planning and once the stock level dips below this value, you can configure system to generate PR, orders automatically. It has its relevance in MRP and CBP.
Safety stock is not used in production.
Minimum Safety Stock
    The quantity that defines the lower limit for safety stock. This value cannot be exceeded.
    The safety is checked to see if it is greater or equal to this lower limit.
    The lower limit is checked if you use an availability indicator which shows, according to customizing settings, if the safety stock is to be calculated again in a forecast. If the safety stock is lower than this level in forecasting, the safety stock is automatically increased to the value of the lower level.
The safety stock must always be greater or equal to this lower level (minimum safety stock)
Hope this will help help you.

Different safety stocks for differnt storage locations?

Hi all,
Can any one tell me if it is possible to set two different safety stocks for two diffetent storage lacations for one materila?
If yes, How?
Thank you,
Utpal

Hello UNP,
Normally, planning is useally carried out at plant level, however you can do MRP at Sloc level as well.
Safety stock is planning data which is defined for entire plant where as reorder level and replinishment quantity can be defined saperately for each storage location, but not safety stock.
hope this helps.

Forecasting Based Planning with Dynamic Safety stock Calculation?

Hi Guys:
Based on the client requirement we are going with forecast based planning i.e based on Sales historical data , rather then buyer determining how much amount of safety stock need to be maintained ,
Can system calculate/propose safety stock based on lead time and service levels set for that particular material?.
how to load historical sales data into the system before go Live , so when they run MRP Run ( using forecast based Planning ) -> Planning orders>PO are triggered? or is there any alternative ?
Thanks
Sweth.

Hi.
Range of coverage profile in material master MRP2 view
The range of coverage profile contains the parameters for calculating the dynamic safety stock. This is a statistical calculation on the basis of average daily requirements.
Use
The dynamic safety stock is calculated depending on the requirements within a specified period and the range of coverage.
Dependencies
The range of coverage profiles (period length for calculating the average consumption, range of coverage, and so on) are maintained in Customizing in the MRP screen.

Sweth, you are asking for consulting, and in my opinion it is way beyond what can or should be reasonable to achieve in such a forum. You are asking complex questions, that most probable have more than one possible answer.
I suggest that you get on-site help from a knowledgeable and experienced consultant. These are crucial business issues, and should be dealt seriously.

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

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

Is there any way of actually moving a picture around, (arranging photos in a single album), in either of these apps???? They claim to be able to "Organize" or "arrange" Photos, but for the life of me I can't figure out how......could you recommend any apps that actually allow someone to move individual photos around on an IOS Device.

No, reordering within folders and albums is not supported. the yare arranged automatically by date. I found this, but I have not used any of the apps besides iPhone. You might check the descriptions to see if they do what you need.

MRP with Safety Stock

Hi All,
I am working on a trading Company. I have one scenario for Make to Stock, whenever the MRP will run it should consider the safety stock and the MRP should be run through the reorder Point. As i do not have much idea about the MRP, so please guide me on this. Please give me step by step Procedure to do this. What MRP type,shall i choose while creating the material master and which lot size? Its will be better if you clarify with an example.
Sure,Points will be awarded.
Thanks in advance.

Hi Dharama,
I have run the MRP same as the example given by you for Lot size HB and MRP type VB as--
Ex. Stock 50
Reorder point 60
safety stock 30
MAx stock level 100
When MRp run system create P.R for 50 no's.
I understood the first two line items as we have the safety stock as 30, so it will be reduced from the avalaiable quantity 50. It will become as 20.
But after that, how the system is calculating on the reorder level and the maximum stock level. Please clarify me on this.
Thanks in advance
Sure, Points will be awarded.
