MRP - project stock - safety stock

Hello,
My MRP plans on a project stock.
When I try to fill in the field "safety stock" in material master data MRP plans the safety amount on unrestricted use stock. I would like it to be planned on a specified project.
Do you know how to do it?
Best regards
Piotr

Hi,
procurement for safety stcok will always happen wo ac assignment. So you may have look for use of some other parameters like lot sizing or minimum lot size fields etc.

MRP Not considering Safety stock

Hello
We have settings as 1000 for safety stock . if the stock went below 1000 , MRP is not pulling the stock for the confirmation of the Production order. we checked the safety stock indicator in the Availability check for the Prod order confirmation . What ever the stock are available ( only unrestricted stock we want to consider for the availability check )
Any suggestion please.
Thanks
JJ

Hi,
When your stock level goes below the Safety stock, then MRP will trigger a planned order to maintain the planned order. In your availability scope of check, if you checked the safety stock, the system will allow to consume the safety stock by posting the goods issue, if the tick is not there, it will not post the goods issue, saying insufficient stock is there.

Maintain plant specific safety stock

How to maintain plant specific safety stock for the same material.

Hi swetha
First Go to T : code : MM02 : change Material
Enter plant number for which u want to enter Safety stock
Goto MRP-2
Net Requirement calculation
enter safety stock
Use of safety stock :
Safety stock
Specifies the quantity whose purpose is to satisfy unexpectedly high demand in the coverage period.
The risk of shortfalls is reduced by having a safety stock.
Procedure:
With manual reorder point planning, you can enter a value in the material master record. However, it is merely for information.
With automatic reorder point planning and forecast-based planning, the system determines and adjusts the value automatically for forecasting purposes.
Hope ths solve ur problem
please reward points

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 ,

Safety stock and safety period

Can anybody help me in understanding the effect of safety period in MRP..
CAn anybody give me an explanation with numbers so that i could test and understand..
Please help me out..

Dear
There are plenty of earlier posting on Safety stock and safety periods .
Safety Stock : This is one kind of Un-restricted stock which will be used to full fill the un-expected damand for any material apart from the normal stock .Safety Stock calcuation depends on requireiment .It can be pre-defined ( manual safety stock -MRP3 view-Safety Stock ) or Automatic Safety Stock based on the MRP Type set up in OMDQ.If you want automatic safety stock , then it will calcuated based on Forecasting view parametrs , forcast model , MAD, BASIC value calcualted wheil excuting Forecasting collectively or individually .
Safety Stock Calcualtion happend based on following CONDITION :
1.MRP type should be Forecast Base MRP -VV,VB,VS,V1,V2.Here MRP type calculates the Automatic Safety stock based on the Forcasting View Maintained in MM02 with proper Consumption History .( 261,501 etc update control in MMR through OMJJ set up --Please check MMR Forcasting View -Cosnumption Histry at least 6 months are there or not ?)
2.In MRP Type -SPRO-MRP-Check MRP Type -Select any one of the MRP Type like VV , you will find that Calcualtion of Reo-Order Point and Safety Stock Check Box Ticked .Based this set up and above Forcasting view , safety Stock will be calcualted with certain formaul .Here in the Material Master MRP3 view u need to maintain Service Level Percentage of that Material whcih will be consideredr as Service level factor to calcvualte the Safety Stock automatically based on the MAD and Basic Values calcualtion in Forcating View Individually (MM02) or collectively in MP38 .
Hope this above facts will help you to understand the calcualtrion of Safety Stock .
Formula : Safety Stock = R x Sq.rt. W x MAD
Safety Stock = R x W x MAD
Refer our earlier posting on the similar issues :
Automatic reorder point calculation
safety stock and min safety stock
Hope it clarifies

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.

How to consider unrestricted stock for the run of MRP project?

Hi every one!
We are facing a problem using MRP on project stock.
We would like that the MRP takes unrestricted stock into consideration while calculating quantities to order for project stock.
For example, a project request 100 pieces of material X.
We have already 25 pieces of material X in unrestricted stock and 0 in project stock.
When I run MRP (MD51), it creates a Purchase Requisition of 100 pieces on the WBS element I have defined and not 75 as expected!!!
By searching in documents and forums, I have read I have to set the value "2 - Collective requirements only" into the field MRP4 > BOM explosion/dependent requirements > Individual/coll. of the Material Master.
I have done it but it doesn't change anything.
Thanks in advance for your support!!!
Bogdan

Hello guys!
As told, here I come with news about my problem.
Finally, the Strategy Group didn't solve our problem.
We didn't solve our problem as planned but we have found another way to work.
Instead of including the unrestricted stock in the MRP project, we use transaction CO46 to have an overview of the unrestricted stock of all the components of the project's BOM.
Based on that overview, the user can make stock transfers of the available quantities from the unrestricted stock to the project stock.
I hope it can help people having the same problem!

Automatic reorder point and safety stock caluclation- MRP type:V2

Hi,
I want the system to calculate reorder point and safety stock. To simulate this i created one material with
MRP type:V2, service level as 97%, Forecast model:D,Hist. period:12,Forecast periods:12, and I entered
the historical value for past 12 months as 100 nos in material master.
04.2009     100
03.2009     100
02.2009     100
01.2009     100
12.2008     100
11.2008     100
10.2008     100
09.2008     100
08.2008     100
07.2008     100
06.2008     100
05.2008      100
Then I went to MP30 and executed the forcase.When I checkd the material master the system has calculated the reorder point as 14 nos. But there is no value updated in safety stock field.
Now I have two questions.
1) How the system has arrived the reorder point value as 14 nos.
2) Why there is no safety stock updated in material master.
Could u please clarify this.
Thanks and Regards
Purushothaman

Hi,
This is further to my preivous mail. I have changed the consumption values and now i am getting the safety stock.
MRP type:V2, service level as 97%, Forecast model:D,Hist. period:12,Forecast periods:12, and I entered
the historical value for past 12 months as.
04.2009     100
03.2009     80
02.2009     110
01.2009     85
12.2008     90
11.2008     95
10.2008     125
09.2008     90
08.2008     90
07.2008     92
06.2008     101
05.2008     100
After executing the forecase the sytem has calculated the below parameter.
Basic value:95.759
MAD:11.448
Safety stock:10.252
Reorder point:23.658.
Can anyone explain me how these calculation arrived.
Thanks and regards

How to make MRP run based on Target Safety stock

Dear Experts,
For our MRP-planned materials with safety stock we would like MRP run to take into account target stock level defined for each month.
for example: we know the target stock level values will be for M1 = 1000, M2 = 0, M+3 = 5000 etc.
MRP should then propose orders to replenish up to the target stock level at the end of each month:
needs for current month = (target stock level defined for current month minus safety stock)
needs for M1 = (target stock level defined M1 minus safety stock)
needs for M2 = (target stock level defined for M2 minus safety stock)
etc
Do you know if there is any simple way to achieve this?
Thanks you!
Elynn

Dear Experts,
in my company, we are facing exactly the same issue, we would like the MRP to consider a target stock exaclty as described by Elynn. To be more clear, if we could reproduce the TDSS like in SNP in MRP, we'll be happy !.
We imagine already to manage the target stock level in APO DP and released into ECC6 as a different MRP element than Forecast. this target stock should not be considered as forecast neither consumed by any sales order. Only to force the MRP to generate planned orders to increase the final stock when needed. This is only an idea, we have nothing tested yet.
someone have an idea if there's a standard solution for make this ? I mean, why this fonctionality exist in SNP but not in MRP?
thanks for any help

Is there any way plan safety stock at subcontractor in MRP ?

When the stock is at vendor ( material provided to vendor)
and if we wanted keep safety stock at vendor by entering safety qty in material master .After MRP run system ignores and planes addition requirements which is unwanted .Is there any way to fix for this issue ?

Define Safety Stock Availability
In this step, you define the percentage of the safety stock to be
     available for planning. This function is used to avoid a situation where
     orders proposals are created unnecessarily by the system to cover small
     shortage quantities.
In MRP, the system usually carries out the lot-size calculation for every
     shortage and creates an appropriate order proposal or - if already
     available - a firm receipt with a rescheduling proposal.
However, it does not always make sense for a new order proposal to be
     created for every small shortage. These order proposals must all be
     managed, converted, placed in stock and settled. If you want to save
     yourself this effort, you can make a portion of the safety stock
     available for planning. This has the following consequences:
     o An order proposal is not created until the stock level has fallen
        below the safety stock available for planning
     o If the shortage exceeds the portion of safety stock available for
        planning, then the system creates an order proposal in the planning
        run that covers this requirement and that also replenishes the safety
        stock.
o The portion of the safety stock available for planning can only be
        determined using the MRP group. Therefore, to determine that a certain
        percentage of the safety stock of a particular material is to be
        available for planning, this material must have been given the
        appropriate MRP group in the material master record.

MRP Planned % Safety Stock Not Generating Supply in R12 ASCP

Playing with MRP Planned Safety Stock in an unconstrained plan. See safety stock in the horizontal plan. See safety stock in the pegging tree. Yet this type of safety stock is not generating any supply recommendations. However with "regular fixed quantity" safety stock the plan is. Thanks in advance.

Hi
If I understand your qn correctly., user defined SS is working and MRP planned % is not. Have you setup MRP planned % such that you gave the SS method., bucket days and % for the item attributes?
Also make sure that you have demand for the item since it looks at your demand in future,adds up demand within the bucket days and applies the % .
Thnx
Partha

Mrp requirement qty including safety stock

I have tested and got results as follows with VB/EX:
RO Point = 10 ea
Safety stock = 5 ea
Stock = 5 ea
But the mrp element generated for 5 ea only.
I need to get requirment qty considering the safety stock also.
HOW TO INCLUDE SAFETY STOCK IN REQUIREMENT QTY?
warm regards
marias

Hi,
the safety stock is relevant when you are carrying out goods issues.
the system will stop you from placing orders against the safety stock (because you don't want to sell this you want to keep it for emergencies) and yet it will allow you to goods issue to a delivery from safety stock (because that is why it is there, to ensure that you have spare items in case of shortages).
You control what can and can't issue safety stock by using different configurations for the availability checks for each function..
So even though the reorder point MRP seems to ignore safety stock it still warns you when you fall below this (with an exception message) and it is still used for goods issues and transfers etc.

Dynamic update of safety stock in SAP R/3 systems (ECC 5.0 version)

Hi Friends,
Forgive my newness to SAP. Let me explain the problem i am facing in SAP. I want to identify the parameters to dynamically update the finished goods safety stock for each depot by SKU wise.
Current process :- Safety stock is calculated manually and updated by using Transaction code MS02 in the system.
It would be highly useful if i know the flow in SAP system and how the current process can be changed?
If more info is required i'm ready to give.
Thanks in advance

Hi Mario Adler,
Thanks a ton for ur answer.
Will it update safety stock for finished goods in each depot by SKU wise? Raw material safety stock isn't my concern.
project description : Manufacturer of chemical goods , 70+ products,350 skus
Distribution : factory to depot (bulk volume)
Mother go-down to depot(Stock transfer)
No of depots :33,factory:3,mother go-down -1
Sales forecasting is done in excel for every month and updated to SAP via BAPI. After that DRP,MRP and other runs takes place.
What are all the areas i need to touch in to get the parameters to update the safety stock?
Regards
Arasu

Report for Reorder point, safety stock, current stock and fixed lot size

Hi,
Purchasing Dept. is looking for a report which can give list of materials falling below the reorder point, so that they can go ahead and create procurement proposals for those materials.
They also want to see the Reorder Point, Safety Stock, current stock and fixed lot size in the same report.
Let me know if there ia any standard report availbale which displays the same or any approach to get the same.
Thanks in Advance.
Regards,
Shankar Goud.

Hi,
There is no standard report because this is meant to be managed by the MRP run.
The MRP lists show all materials that have a problem (such as stock below reorderpoint) but MRP generates requirements for these anyway and so all you need to do is to look for the MRP generated requirements (requisitions?) and you have your list?
Are you using MRP?
If so then please use the standard functions in MRP to get this.
If not, then WHY NOT?

Safety stock not covered by schedule lines in planning run

Hi !
In our organization we are trying to implement scheduling agreements and automatic creation of delivery schedule lines through MRP. We have MRP type PD and it considers the reservations created by PM orders and Production orders as requirement elements. When I do the planning run, it creates schedule lines for the PM order reservations and purchase requisition for safety stock. I need it to create schedule lines for all scenarios. Kindly help and suggest a solution.

Satya

Hi,
