Safety stocks and STO's

Hi everyone,
I am new to APO but I am writing a functional spec. The safety stocks and STO's obtained after running SNP optimizer must be sent to third party system. I have to do the field mapping. Can somebody tell which table and technical name I should use. I know we can use /sapapo/rrp3 but I am not sure. Can somebody help...

Hi Bopanna,
We are using version SCM5.0 and a using planning book which is copy of standard planning book 9ASNP94. We have assigned correct KF function (3003) to safety stock key figure. I stillc nat figure out whats wrong

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

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.
Regards,
Pavan

Dynamic Safety Stock and Calculate based on past consumption

Hello experts,
I have set up my coverage profile in configuration for dynamic safety stock. However, the value is going off of the current net requirements in the system. How do I set it up so that the target stock level (DSS) is determined by 30 days of our past consumption and so many days of near future requirements?
I assume I need to set up the MRP 3 tab in a specific way. These materials that will be using dynamic safety stock are not forecasted, therefore, the material master had PD as MRP type (not VM or VV as discussed for setting DSS with forecasted materials), lot size of DY, and the coverage profile.
Please let me know.
Thanks.

Hi,
Hi the configuration should be like this..
First Create range of actual coverage profile SPRO and enter the following data.
Period Indicator - M
Number of Periods - 2
Type of Period length - Working days
Number of days per period - 30
Range of coverage in the first period - target - 30
Then assign this profile to the material in MRP3 screen in the field range of coverage profile field.

MRP with reorder point and safety stock and planning calender issue

Hi,
We are using currently MRP type PD and using Scheduling agreements and after the demand management changes when ran MRP the delivery quantities are fluctating in higher range and vendor complains about it so to avoid this we are constantly changing GR Processing days in material master? how can we avoid the drastic changes on the order quantites on scheduling agreements with out changing GR processing days.
For example : we constantly manufacter 480 vehciles per week and some time because of holidays it will be 320 or 560 per week then the forward scheduling agreement quantites instead of 480 parts week(twice a week delivery) goes up and down and vendor needs a at least a range for his prodcution?
I was thinking to use Reorder point but when i changed the MRP type VB then i cannot see forward scheduling agreements at MD04? does MRP type VB or V1 will allow forward scheduling also like 120 days ahead of planning?
Appreciates everyone time and help.
Thanks and Regards,
Siva

you can use MRP time fence to restrict the changes in planning data for specified horizon. For example If MRP time fence = 30 days, no changes in planning data will be allowed for coming 3o days unless you manually intervene.if any new requirements came in this period , they will be planned automatically at the end of this period only.

Report on Rorder Point and a safety stock

Hi,
Pls adivse, by which tcode, i can get a report on Rorder Point and a safety stock for the material.
ie. my client want to have a report abt the material status for reorder stock

Hi,
The safety stock and re-order point are plant specific details
The values can be checked from SE16 - table MARC

No planning file entry for safety stock

hello!
i do not have a planning file entry for safety stock. my material has required safety stock and no quantity on plant stock. therefore MD01 should create a purchase requisition - but is does not. i do not have an entry in the planning file as well.
any ideas what could be the reason?
thanks!
matthias

Hi,
- First of all check whether MRP is activated or not for Perticuller Plant.T.code is OMDU.
- Which MRP type is maintained for that material?
- In rare cases (Materials uploaded by LSMW using Badi) it is observed that system miss to make the entry in Planing File.So better will be set a Back Ground job to activate Planing file OMD0 or make manual entry using T.code MD20.

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.

Safety stock Warning message ?

Hello Friends,
Need some help in creating a new functionality,Currently our customers can order a large quantity for any given material. There is no check in place that warns the customer service rep (CSR) that this will stock us out or that this order is 1-2 times our safety stock. I would like to get a function in SAP so that at order entry, if a CSR enters a quantity that is more than 50% of our safety stock, they will receive a warning stating that this could wipe out the inventory for other customers.
I would like to be able to set-up this functionality for a certain set of materials that have safety stock and that are active and high-volume materials.
Please advice what configuration changes needs to be done in order to fullfill this requirement.
Thanks in advance.
MO

Hi Mohammed
there are no configuration changes. I hope the following would work.
1. How do you identify high volume materials.
2. How do you identify Active materials.
You must find a way to do these or choose some field in the material master for which this check needs to be performed.
Once this is done you can write code in MV45AFZB to perform the check at VBAP level.
Thanks

CIF Exit for updating APO field SAFETY STOCK METHOD from R/3.

Hi All,
I have a requirement for updating filed "Safety stock Method " in APO from R/3.
We can do it through transactions CFM1 and then CFM2 in R/3.
This happens when we make changes in MM02 in R/3,
for fields,
In ECC, Goto MRP2 view in material master
Safety stock (EISBE)
Safety time/act cov. (SHZET)
STime period profile (SHPRO)
Currently, we are using a exit : Exit_saplcmat_001,
but it only gets triggered when we make changes in safety stock and safety time.
where as if we make changes only in STime period profile, and don't make any change in safety stock and safety time,
in this case the exit is not triggered.
Now, we are looking for an exit, which will get triggered even when there is no change in safety stock and safety time,
where as there is change in STime period profile.
Please suggest what can be used.
Thanks & Regards,
Rahul A

Hi,
You may need to include the field in some structure also.
eg. for sales order interface we add z fields to structure /SAPAPO/KOMGO

Dynamic safety stock in PP/DS

Hello,
My question is about how PP/DS uses dynamic safety stock. I use safety stock keyfigure in SNP to calculate dynamic safety stock and make it available for PP/DS. When I run planning heuristic in PP/DS, does heuristic go and execute the macro?
Let me give an example case.
A is header, B is component of A. When I make a full planning run in PP/DS, first A is planned, then using dependent demands from A, B is planned. While planning B, safety stock also must be calculated. Is this process an inteactive process between SNP and PP/DS? I mean, PP/DS creates planned orders for A, then dependent demand generated for B. When it comes to plan B, heuristic calls SNP and macros calculate SS and SS is used in PP/DS heuristic as requirement? Is the process like that? or Do i have to run SNP either online or bacgrounf first, calculate SS there, and then run PP/DS heuristic?
Thanks,
E

Somnath, Harish;
Thanks for your help. I read all these notes and threads. But I could not find the answer to my question.
First of all, I am using SS method MB. not an extended safety stock method.
I want to implement the same SS calculation as in R/3 coverage profile. In coverage profile, average daily requirement is calculated using X weeks of demand, and Y days of SS is calculated. I want to do the same calculation in APO.
We are using PP/DS for short term planning. Here my question is in which way SS is calculated while running planing heuristic in PP/DS. I listed 2 possible ways, can you please tell which way PP/DS work?
1) PP/DS will run for the example BOM structure I gave before. So, in this example, I need to run planning for header material first in order to find dependent demand for component. Then I need to make planning for component. If I calculate SS in SNP before starting to run PP/DS for header material, SS for component is calculated in SNP using the demand calculated before PP/DS planning run. Is this how dynamic SS works?
2) or when I run planning for component, does PP heuristic call SNP macro and calculates SS with the most updated demand situation?
Thanks,
Ergul

Dynamic Safety Stock wih Safety daysu2019 supply

Hi
In APO PP/DS, my compagny want to set up for several products, two safety stock :
1- Dynamic Safety Stock in order to prevent when actual usage exceeds forecasted demand
2 - Safety day's to prevent when time it takes to receive a replenishement shipment exceeds the projected lead time (usual problem in our business)
For this two cases we use
1- MB
2 -SZ
So my question, how it's possible to mix this 2 safety stock methods? Is possible to create a custom method or custom heuristic in order to do that?
Thanks for your help
Youri

Hi
We have ever try without success other solutions as :
SM and MM
MB with Good Receipt Time in APO = ( Good Receipt in R/3 + Safety Days )
The only solution seem AT/BT method but we can't make difference between safety stock and safety days during monitoring
Thanks for your help
