Safety stock planning and use of CTM in APO

I want to use advanced safety stock planning and CTM in APO for a range of finished products.
For advanced safety stock planning, the available safety stock methods are AS, BS, AT, BT.
For CTM, I want to use time based safety stock method MB.
So how can the use of these different methods be reconciled?
Ady advice appreciated...

Hi,
Please check following SDN threads:
Re: CTM ignores Extended Safety Stock Methods (like BS, BT etc...)
Please also check OSS note 426563 .
For Planning a time phased safety stock ( e.g. when using advanced safety stock methods from SNP) CTM provides two alternative methods which have their own restrictions:
1. Standard saftey stock Planning .The standard safety stock method of CTM consists of two internal runs of CTM engine which are not visible for the user. Because of this two runs it is not possbile to consider decreasing safety stock. CTM interval planning can be used herein.
2. Alternative saftey stock method (Control parameter SSTOCK_MODE). This method carries out only one run. However there are some restrictions. For details of the above, please check oss note 1413545.

Safety Stock Planning not completing - /n/SAPAPO/MSDP_SB T-Code

While running Safety Stock Planning (/n/SAPAPO/MSDP_SB transaction) in SCM for products at a particular location, the system hangs and never completes the process. The message at the bottom is u201CDetermining Demand Information: <location> <product>u201D. This process works fine when running on any product at another location.
In order to avoid the above infinite/endless loops, in the Safety Stock Planning Profile, the checkbox for Execute Cycle Test was selected. While this did resolve the endless loop that the program was running, it now results in an error.. Now, it gives an error message "Cycle found for product <product> at location <location>".
Any ideas on how to resolve this issue?

Hi,
Thanks for the reply....it was really helpful.
We verified T-Lanes by using t-code WUF. There was transportation lane between location 6000 and location 6010 and vice -versa with all products selected. So, we put a block on all products on one T-Lane.
Thanks.

What is Formula for 'BS' Method of Extended Safety Stock Planning ?

Hello SNP Experts,
I have a Important Question regarding Extended Safety Stock Planning Calculation in SNP Module.
I have read the SCM Help, SDN Forums and SNP Training Course help, but am unable to find the Formula to Calculate Safety Stocks using the Beta Service Level (Method 'BS') for the Extended Safety Stock Planning Methods.
Reading the help, training material, past SDN Questions I do understand the Standard Formula for Safety Stock is ...
S.S = ServiceLevel x SQRT (ReplLeadTime) x StdDevDemand
However there are Factors like below that are definable in the Location-Product Master ...
1. Forecast Error %
2. Replenishement Lead Time Error %
3. Min & Max Safety Stock Levels
4. Beta Service Level
5. Max. Stock Level
How are these Factors used ? What is the Formula using these Parameters to Calculate the Safety Stock ? The Calculation in SCM-APO is not clear from anywhere.
I am specifically interested in the Method "BS".
Can anyone Guide me ? Points Guaranteed if a reply covers the exact question above (I have done some research before raising this question on Forum).
Regards,
Ambrish Mathur

Harish,
I'd seen these forums already. Thanks for responding.
This 'secretive' calculation is quite annoying. If SAP does not Publish any documentation around the Formula, how can the Customer be convinced to use SAP's Safety Stock Calculations (no wonder many SAP Customers are going the 'ToolsGroup' way of Safety Stock Calculations).
On Safety Factor (I saw in your notes) I am aware that
a factor of 2.33 equates to 98.6% service Level from long back based on Normal Distribution. The Formula as known much earlier is this ...
SS = SafetyFact x SQRT (RepLeadTime) x StdDevDemand.
based on Normal Distribution.
However there are new Fields in APO since ...
Is there no documentation whatsoever on how the 2 Fields - 1. Forecast Error %
2. Replenishement Lead Time Error %
are used at all in the SS Calculation ?
Where do these New MasterData Parameters Plug-in ?
The other change now is in SS Planning, the SSs could be different for each Time Bucket in Future. How does Beta Service Level also impact the Calculation ?
Is there a URL / Book someone can point me to ?

Ambrish

Advanced safety stock Planning -

Hi,
Is their any method to do the advanced safet stock planning depending on the stage of Product life cycle.
i.e. intial stage the safet stock planned should be less, should increase during Maturity stage and should gradually decrease to ero during the decline stage.
Please respond if anyone has done this in past or if any standard SAP functionality exist for the same.
Thanks,
Sanjog

Hi Sanjog,
Mainly In DP area Phase-in and Phase -out of the product life cycle are planned. So using the advanced Safety stock planning your safety stock should balance the demand and supply variability.
Generally if you look your Safety profile, it will be the offset of your demand plan and also in areas where you expect phase-out and spike in demand safety stock will be constant based on the strategy Alpha/Beta you use in advanced safety stock planning.
Also, I think you shouldn't treat this case anything specific as the KPI's will correct the model you are using anyway, unless the Lifecycle is very short.
Hope this helps.

*** Question How to load a file into BI-Integrated Planning and use WAD 7.0

Hi, I created an manual DTP upload to my planning infocube and it works fine. The transformation rules convert 0CALMONTH into the relevant Calendar and Fiscal characteristics. So all of my Time Characteristics are fine, both Calendar and Fiscal.
However, When using the "How to load a file into BI-Integrated Planning and use WAD 7.0" solution, only the Calendar Characteristics are populated and not the Fiscal. The upload application somehow knows to populate the 0CALMONTH2, 0CALQUART1, 0CALQUARTER, and 0CALYEAR.
How can I get the upload to populate my Fiscal Period Characteristics?
Would it be best to modify the "Upload Application, or can I write a planning function to update the fiscal characteristics, or some other way?
Thanks!

Safety Stock Issue

Hello Gurus,
We are in SCM 4.0 and currently we are facing an issue in safety stock calculation.
We run a macro to calculate the safety stock. The safety stock for a particular bucket is calculated by the sum of total demand of next consecutive 4 buckets. The problem is that the macro works fine if we select a single product-location combination but when we select a product at multiple locations combination (aggregated level) the macro doesnt work. The value is not displayed in the planning book. However, we could see the total demand value for that particular bucket.
Hope I am clear and please help me on this.
Thanks,
Sai

Hello all,
I have a quick question:
Do we need to maintain the data at Location-Product Group level to go for Aggregated Safety Stock Planning?
Let me explain my case:
We have the following selections at Location-Product level:
Sel1: Prod1 at Loc1
Sel2: Prod1 at Loc2
Sel3: Prod1 at Loc3
When I make either of these selections individully in the Planning book the safety stock macro works fine but if I make any of these two selections or all the three selections at a time, then the values does not show up at the Total but I can see the values at 'Details' level if I select Location at the Header Information.
We are thinking of Aggregated Safety Stock Planning and We do not mainatain the data at Group level. Can we still go for Aggregated Safety Stock Planning?
Could anyone give me some suggestions on this?
Thanks
Sai

Safety Stock Methods SB, SZ and SM - When to apply what method?

Dear Experts,
i have searched the threads for a good explanation of safety stock methods (especially for safety stock methods SZ, SB and SM). I have to admit that i did not fully understand how the SM method works exactly. It would be great if you could possibly share an easy-to-understand example. Furthermore i am looking for a way to determine for what rawmaterial_location combination we need to use what Safety Stock Method (SB, SZ, SM). Maybe you could share a few examples in terms of raw materials, characteristics for these raw materials, what method to choose and reasoning for choosing this method.
Thank you very much for your support in advance!
I am looking forward to your answers!
Best regards,
Christian

Hi
Please refer OSS note 504253 . This will give you an idea about the safety stock methods. This note also has links to other notes that explain safety stock planning

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

ASCP and Safety Stock Pegging

Hi,
in our ASCP plan, currently we have items with Safety Stock values manually inserted valid over all planning horizon.
Therefore all the safety stock is NON-TRANSIENT.
Actually we have Priority Based pegging with:
MSC: Include Safety Stocks in Priority based Pegging: YES.
What is appening is that ASCP peg On Hand quantities to FORECAST DEMAND, then pegs other supply type to SAFETY STOCK Demand.
I would like ASCP to peg OH to Safety Stock Demand (DUE on the plan start date) before Forecast demand (due in the future).
Someone knows how to obtain this "feature"?
Thanks in advance.
Giacomo

Giacomo,
I'll give you a few pointers, but this may be difficult to achieve. Try this as a test.
I assume you have a constrained ASCP plan. This question wouldn't be as relevant in an unconstrained plan because the demands would just be calculated and priority pegging isn't that useful. .Is that correct, you have a constrained plan?
The key point is that you mentioned is that you have NON-TRANSIENT safety stocks. This means that you are setting a value due today for 100 units and at the end of the plan, you still want to have 100 units of safety stock planned.
ASCP priority pegging logic has these rules:
1. Any supply quantity that pegs to NON-TRANSIENT safety stock CANNOT be used at a future date to peg to real demands. [It's not going to happen]
2. Any Supply quantity that pegs to transient safety stock CAN be used at a future date (when the corresponding dip in safety stock occurs) to meet demands. [This means that it can release the supply and re-peg to a future demand].
Independent Demands have a seeded demand priority by default. The first two below are set by a profile option, safety stock is always the lowest priority ( a number something like 99999 where the higher value is lower priority)
1. Sales Order = 10,000*
2. Forecast = 100,000*
3. Safety Stock = 999,999 (not sure of this internal value)
Set by a profile with a name like msc: default sales order priority
For priority pegging setup instructions, please see the ascp user guide. The basics would be the use of two profiles mso: demand window size and mso supply window size. This determines how ascp will select and sort your supplies and demands for pegging. It starts at the first demand date or supply date and selects that many future days of demand and supply to sort and then peg.
You also setup a priority rule that determines how ascp calculates priorities for pegging. To accomplish what you want to do, you would have a rule like
1. MDS & Sales Order priority
2. Schedule Date
This is a commonly used example. The pegging process will the select the number of days you have chosen and sort the demands based on their prioirty.
Sales orders are more important (to you) than safety stocks, but not forecasts. You want the safety stock to peg the on hand, not a future forecast. This can only happen because you have mso: demand window size set to a number of days where pegging sees the future demand in the same sort. I haven't seen this requirement (SS higher priority than forecast), so you'll need to test my suggestion.
Set the value of MSC: Default forecast priority = A huge number (higher than 999999).
The intent is to make the demand priority the SAME as a safety stock demand. In this case, with the priority rule I suggested, the schedule date will determine the pegging order.
I think this will get you close. You can view the internal proirity calculated by ASCP for the independent demand by selecting that order in the pegging details and then rightclicking to select the properties. The pegging details wil show you the priority value that was used.
Hope this helps.

Why does planning indicators change when the safety stock change?

Hai All,
I created a BOM for a finished material (FM1)and entered another finished material(FM2) in item list.
Now in MRP, I did single item multi level planning for the FM1. I checked the planning file entry through MD21 and it has NECH and NECPL marked. I checked for FM2. None of the indicators are set. Then I have been to material master for FM2 and in MRP2 screen and changed the safety stock to 950. Then I checked the plannig file again and I see the indicators NECH and NETPL are checked. I then made the safety stock 0 and checked the planning file. There is no change.
My question is why were the indicators NETCH and NETPL checked when I increased my safety stock for material FM2 from 0 to 950?
I understand that NETCH is the planning for Net changes and NETPL is for planning for changes in a horizon.
Are these indicators set because I made a change to the material? or is there any other reason?
Thank you.

Visu
The planning indicators change when there is an amendment to the planning situation that requires MRP to replan a material. Essentially, by upping your safety stock from 0 to 950 you are requesting that the MRP system replans that material to ensure that there is sufficient safety stock available.
Hope this helps

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
