Target Days of Supply

Hi,
Is there any method in APO of smoothing out a
supply plan similar to the range of coverage profile in R/3.
What we would like is that:
APO looks out say 100 days in the future.
Adds all demand.
Divides by 100 to get an average daily demand.
Creates a supply plan based on this average.
Thanks,
L

Hi Liam.
I believe that you could acheive this in SNP with the use of macros manipulating the target stock level key figure.
You could include a TS key figure to capture average daily demand and include it how you require in the calculation of the target stock level.
Under normal conditions, Heuristic run aims to reach the target stock level in each bucket.
Haven't tried it, but would suggest caution when moving away from standard SNP macros and lots and lots of testing.
Hope this helps.

Target Days of Supply in PPDS

Hi All,
I am trying to use the Target Days of supply with PPDS.
The documentation says it works but on my tests
it does not.
IN SNP it does work.
Any ideas ?
Thanks,
T

Hi Mike,
I have setup the Target days supply settings in the material
master and I am using the planning of standard lots heuristic.
It works perfectly in SNP ... just not in PPDS.
Any other ideas ?
Thanks,

Target day's supply vs day's supply

Hello all,
Can anyone help me explain the exact diff between target day's supply and day's supply? I would appreciate the help.
Thanks,
Neha

Hi Neha,
Day's supply:is to determine for how long the available stocks and receipts will cover your requirements.
http://help.sap.com/saphelp_ewm70/helpdata/en/39/24a037f11cff7fe10000009b38f889/content.htm
Target days' supply: is maintained in product master to determine the safety stock that has to be produced to cover the number of target days demand.

Targets days supply

Hi Gurus,
Please let me know on targets days supply in PP DS and the effect of it on planning. what are the necessary settings to be maintained for achieving the same ?
Thanks,
Prasanth

Hi Prasanth,
In APO the requirements is rolling that is if you have Forecasting then the forecast for a month it is
disaggregated into days or weeks hence if you plan to have a safety stock planning done by APO this method
of maintaining Target days helps to maintain the stocks at the location all the time so if you define 4 days
as the Target days of supply then at all time Heuristics run or optimizer run will ensure that stocks are
there to meet the requirement of next 4 days as is in your case. In case of shortfall system will generate
a requirement on the Source plant based on the transportation lane.
Settings are maintained in Product Master under Lot size tab (Quantity and date Determination).
Please let me know if you need any further information on this
Thanks,
Harsh

Target Days Supply in SNP Heuristics and Deployment

Dear Experts,
Does the Target Days supply only define the minimum and not the maximum stock levels?
Example: consider a Period P1
The target dayu2019s supply is 20 days, and the Days Supply in Period P1 is more than 20 (suppose 35)
The Total Demand in that week is not big enough to bring the Days supply < 20
Question:
Does the system still create a Distribution Reciept (Planned) in this case and keeps increasing the day's supply of dest location? Or does it create stock transfers only if Days Supply is threatening to fall below the Target Days Supply?
In other words:
Does Target Days Supply only come into picture when Days Supply < Target Days Supply, in which case the system adds the difference (Target Stock Level u2013 Current Stock Level) to total demand while creating stock transfers.
When Days Supply is >> Target Days Supply, does the SNP Heuristic still create a Stock Transfer even though there is enough stock to cater to the current total demand and not fall below Target Stock?
Hope you can help in understanding this concept.
Regards,
Rimjhim

Thanks for your reply.
Please correct if I have misunderstood:
While calculating the net requirement during SNP Heuristic run, the system will apply Target Stock Level into consideration and will only create a Pur Req if the stock is falling below the Target stock.
Thanks,
Rimjhim

How to calculated "Target days' supply" in SOP Planning

Hello all
after input "Target days' supply" in SOP. then run "Create Product Plan"
there will create production plan in screen. thus i used "Target days' supply" strategy.
there have one quesion, how to calculated product quantity?
Thanks.

Dear,
System calculate days supply automaticly, this that no of days required to maintain that stock level,
In the standard planning table, choose Edit-Create production plan-and the desired strategy (either Synchronous to sales, Zero stock level, Target stock level, Target daysu2019 supply, or Plan externally).

Day's Supply

Hi All,
I have one query on day's supply calculations.
Suppose stock as on date( 05-12-08) for a material is 1
1st Requirement which is on (09-12-08) for the material is 4
Then what should be the day's supply.
As per the help 'The range of coverage is then the number of workdays between todays date and the date of the requirement that causes the shortage minus one day. The value after the decimal point is the ratio between the opening stock on the day of the shortage and the requirement on the day of the shortage'. According to it the day's supply should be 4-1+(1/4) = 3.25
But actually system is displying the value of 0.25

Dear
The days' supply for a period is the stock level divided by the average requirements, where average requirements = sales/number of workdays.
Days' supplies are calculated by the system. You cannot overwrite them.
In ur case
DS = 1/4 = 0.25
Ur stock level is 1. & average requirement is 4

Days of Supply

We got daily, weekly and monthly buckets in our SNP Planning Book. We use Days supply standard macro, its calculating correctly for weekly and monthly but not daily. The values are little bit off.
If u select the data for multiple locations and drill down by location, by location the days of supply values are OK. But if u checks the total of days of supply, it doesnt make sense. The total values are neither average nor sum. How to read this total No.
Any advise is greately appreciated.
thx
Jeff

Firstly, the days of supply relationship is not linear in nature (it is not additive). The days of supply (check the macro in the workbench and double click on the macro) macro is designed to work only at Details All level. You can try to swtich that to All Planning Objects to see if it works.
Please check the calculation at Total level anyways - is it that the sum of forecasts during the days of supply = projected stock level in that bucket ?
You may want to check
Hide row Total in Interactive Planning when drilldowned
to see if it is possible to hide the total row.
You may want to try with different data patterns to make sure the calculation is indeed happening correctly at weekly or monthly levels.

Days Of Supply (DOS)

All,
One of the SAP's xApps Analytics Composite Applications for SCM included in 2004s is the Global Inventory View. One of the metrics offered within the application is the actual Days of Supply (DOS). From documentation I see that it is displayed by query 0APO_C12_Q0001 that reads from InfoCube 0APO_C12. I dont have access to the live 2004s system.
Who knows how 2004s determines the DOS value. In release 3.5 the DOS was available in two objects in Business Content:
MultiProvider 0IC_MC02 - Material Range of Coverage Components
The MultiProvider 0IC_MC02 is a union of Material Stocks/Movements (0IC_C03) and Plan/Actual Comparison Material Consumption (0PP_C05).
You can display the number of days during which the current stock of materials will cover future requirements based on the current requirement from production. When calculating the material range of coverage, it is assumed that the average future requirements for production components will be the same as those in the past (constant model). The key figure is determined on the basis of the average production requirements in the last 365 days calculated from the current calendar day.
(0IC_C03) - Material Stocks/Movements (Inventory InfoCube)
You can use this InfoCube to show on the basis of the stock and issue values the number of days during which the current stock will cover future stock issues. When calculating the material range of coverage, it is assumed that the average future stock issues will be the same as those in the past (constant model). The key figure is determined on the basis of the average stock issues in the last 365 days calculated from the calendar day selected.
What I would like to know is whether the Days Of Supply offered by the 2004s is the actual DOS that takes into account the impact the demand and supply have on the inventory on-hand?
Thanks in advance,
Stan

Hi David,
Thanks for the tip on Code Tags.
The logic for Days of Supply is to take the ending inventory (Stock on Hand) for the month then looking forward at the forecast for future months determine the Days of Inventory on Hand (Days of Supply).
In the example Stock on Hand for May is -23 and Days of Supply is 0
However for June 2011, Stock on Hand is 442 so it has coverage for all the days in July (31) and then it can cover an additional day in August so Days of Supply is 32.
The code I placed in original question is just an example of how it could be calculated in Excel.
We would like to create the report in WEBI but we know longer can use Macro's in the version we are rolling out.
Here is the Excel Function I created for Days of Supply: This will give you the code to acheive the narrative I stated above.
It passes Stock on Hand then two arrays. The forecast for future periods and the number of days in each respective period.
Private Function DOS(EndInventory As Single, Forecast As Variant, Days As Variant) As Single
    DOS = 0
    TotalDays = 0
    InventoryVar = EndInventory
    For x = 1 To Days.Count
    TotalDays = TotalDays + Days(x)
    Next
    For i = 1 To Days.Count
    If InventoryVar > 0 Then
        If Forecast(i) = 0 Then
            DOS = DOS + Days(i)
        Else
            If InventoryVar < Forecast(i) Then
                DOS = DOS + ((InventoryVar / Forecast(i)) * Days(i))
            Else
                DOS = DOS + Days(i)
            End If
        End If
    Else
        Exit For
    End If
    InventoryVar = InventoryVar - Forecast(i)
    Next
If InventoryVar > 0 Then
    DOS = 9999
End If
End Function

Reg-Alert Macro-Day's supply not working

Hi,
    We are using Data base alert macros for day's supply of SNP.But it seems macros are not working.Planning book day's supply key figures value not refelcting in alert monitor(amon1).
our setting is 0-30 days-Information;
                     31-50-Warning;
                     above 51-Error
Thanks&Regards
Venkadesh

Hi Venkadesh,
I think you put your indicator upside down.
0 to 30 should be error and avobe 51 information.
Another comments: to check if the macro is working: after running it, in interactive or background, check table /SAPAPO/AM_ALERT to see if you can see the alert or not.
If you can see the alert in the table but not in the profile, then the issue is your profile; if you can't see your alert in the table neither, then the issue is the alert creation in the macro...
I hope it helps

1st and 2nd Receipt days of supply calcluation

HI,
i was wondering how the first and second receipt days of supply are calcuted when viewing in MD06. I went into the configuration 'Define Receipt Elements for Receipt Days' Supply' via menu Consumption Based Planning --> Evaluation --> Define Receip Elements Days' Supply.
However, in this config activity i'm not sure how it differentiates between 1st and 2nd receipt days of supply? Does anyone know where the difference is located in configuration.
Many Thanks, Erik

Erik,
The receipt days' supply indicates how many days a material will last. The system takes current plant stock and specific, predefined receipts into account when calculating the receipt days' supply.
You can define two receipt days' supplies.This enables you to instruct the system to take the less binding receipt elements into account for the first receipt days' supply, and to take only the binding receipt elements (such as production orders and shipping notifications) into account for the second days' supply.
In the IMG node you can define which mrp elements contributes or should be considered during calculation of days of supply.
Typically for most clients, I advise taking firm MRP elements like Production orders & purchase orders into 1st Reciept days of supply as well as 2nd reciept days of supply.
So in IMG node they get X =Take both receipt days' supply into account
For Firmed PR & Firmed planned order they should be considered under 2nd reciept days of supply only.
So in IMG node they get 2 = Only take receipt days' supply 2 into account
Hope this clarifies your question around this concept. More questions please feel free to ask.
thanks,
Ram

Inventory days of supply bex report

Hi experts,
I am working on inventory days of supply bex report which i would like some help on. I do know that we have a standard query for this,however i feel standard wont fit the requirement completely. We have around 3-4 plants. Each plant will have list of material codes which will be maintained in its inventory. These material code are not unique to a plant i.e one material can be stocked for multiple place at various storage locations.
Now where this gets tricky is that material have been classified based on their criticality. for Ex M1001 is classified non critical for plant1001,however this same material code m1001 can be classified as non critical for plant 1002.
I was wondering if any one could help me in the changes i would need to do in my standard inventory flow to incorporate this requirement. The user requirement is that he should have plant and material classification in the drilldown .
Any help would be highly appreciated.
Thanking you in advance.

Hi Rahul
Since you have your classifications in MARC then use material plant infoobject (0mat_plant) if you can find in the std ds your field then activate as navigational and use it in your report.
Thank you

Day's Supply, Stock On Hand, Safety Penalty and Delay Penalty

Hi All,
1. Day's Supply and Stock Hand at the Distribution Center
Checking the planning book, does the stock on hand KF represent also the day's supply? or only the receipts?
ex. of what i see in the planning book:
   receipt = 100, stock on hand = 100, day's supply = 7
There is also a case where I see 128 days as my day's supply but i have no stock on hand.
How is the day's supply determined? How do I know the number of stocks it represent?
2. Safety Penalty and Delay Penalty
If my safety penalty is higher than my delay penalty, will it be true that it will prioritize to meet the required safety stock rather than the demand?
Hope someone can help me on this.
Thanks a lot.

Thanks PATHAN Mahadalikhan.
Additional Question.
What if,
D1
Demand           300
SOH                500
Day's Supply     7
D2
Demand           300
SOH                200
Day's Supply     7
D3
Demand           200
SOH
Day's Supply     7
D4
Demand            0
SOH                 0
Day's Supply     7
D5
Demand            0
SOH                 0
Day's Supply     7
D6
Demand            0
SOH                 0
Day's Supply     7
*this will be like this until the end of the plan.
What can be the reason behind the day's supply reflected even if there is no more demand and Stock on hand?
Thanks.

Traffic lights Vs day's supply

Hi,
In MRP collective lists, system is showing red signal lights to all the materials and showing the message "3.0- days is less than limiting value of 0.1-"
In the day's supply,1stRDS and 2nd columns system is showing the value 3.0-.
In this case, how to change the signal light from red to green?
Can any body please explain the concept behind this?
Thanks in advance.
Sekhar.

hi
traffic light depends upon the day's supply and exception messages.
in md04 collective access , display all materials with MRP controller wise. Press the Tab " define traffic lights" there u can put ur own criterion of days supply and R days supply.
Example how system calculates days supply.
Calculation of the range of coverage: Starting from the current plant stock, the requirements are deducted one after the other along the time axis. This is done until there is a shortage (requirement > stock). The range of coverage is then the number of workdays between todays date and the date of the requirement that causes the shortage minus one day. The value after the decimal point is the ratio between the opening stock on the day of the shortage and the requirement on the day of the shortage.
Stock = 240 pcs
1st day: Requirement for 90 pcs => Stock = 150 pcs
2nd day: Requirement for 70 pcs => Stock = 80 pcs
3rd day: Requirement for 100 pcs => Shortage
Range of coverage = 3 workdays minus 1 + 80/100
= 2 + 0,8
= 2,8
Reward if useful
