QM Lot in Receipt Days Supply

Hi All,
We done the config for Receipt days supply as QM Lot to be considered for both 1st and 2nd Days receipt. But it is not considering. What would be the reason? Whether the issue is in QM or PP?
Is there any possibilty that a particular status of QM lot will not considered as stock?

Receipts Days Supply

Hi All,
Kindly explain the receipts days supply concept.
We have a stock of 25 EA in the plant. We have a demand of 100 EA. When i run a MRP for the material, PR got generated on 26/05/2009 and it is rescheduled to 01/05/2009.
We execute MD06 and it shows the supply as -10.8.
How the system calculated the supply as -10.8?
Please explain.
Regards,
Sureshbabu G.

Hi
Hope this example will be helpful in finding the receipts 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
Purchase orders are included in the days' supply, but not purchase requisitions
1st day: Purchase order for 50 pcs       => Stock = 290 pcs
         Requirement for 90 pcs          => Stock = 200 pcs
2nd day: Purchase requisition for 80 pcs => Stock = 200 pcs (remains)
         Requirement for 120 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

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

Customizing of the days' supply in MD04/MD06

I don't see any difference with the first receipt days' supply and 2nd receipt. We need for the 1st days supply more binding information, like the PO or process order,
for the second we need assigned purchase requistions or firm planned orders. Could you please check.
*Please set the indicator for consumption based planning not on safety stock or reorder point.
Can some one give me steps how to implement the above requirement . I have gone thru the configuartion but need further help .
Regards,
SHD

Shahid,
You need to get your users to clarify their requirements.
I don't see any difference with the first receipt days' supply and 2nd receipt. We need for the 1st days supply more binding information, like the PO or process order,
This requirement is not explicit enough. Tell the users you need an explicit list of the items they wish to include in the calculation for first days supply. They can select from the list found in configuration (these are the only options available):
Production/Process orders
POs, shpg notifications, sched. lines, dely scheds
QM inspection lots
Firmed purchase requisitions
Firmed planned orders
Assigned planned orders
Receipt reservations
Shipping notifications
for the second we need assigned purchase requisitions or firm planned orders
This is explicit enough, but not possible. Assignment of a purchase req is not adequate to delineate. Unfirmed (but assigned) PuReqs will not be considered.
Please set the indicator for consumption based planning not on safety stock or reorder point.
Receipt days supply is configured at the plant level. It will be same whether you are using consumption based planning, or demand based planning. It is possible to have the system calculate days supply "until stock falls to Safety stock level" or "until stock falls to zero"
Once you have your lists of items that are to be included in 'first day' and "second day', go to OMIL. For items to be considered only in 'first day', enter a 1. For items to be considered only in 'second day', enter a 2. For items to be considered in both, enter an 'X'.
If you wish for the system to ignore safety stock (calculate days supply until stock falls to zero), enter 1 in the safety stock field.

Days supply,Recipts days supply

Hi Gurus,
Can someone tell me how does the system calculate the day's supply,Recipts days supply.
I understand these terms but it would be helpful if someone can give an example.
Also what does 999.9- indicate.
Points will be rewarded
Thanks and Regards,
Anshul Goyal

There are 3 types of days of supply..Please come back after going through it
Days' supply
The days' supply displays the number of days that a material will cover if only current plant stock is taken into account.
By using the Days' supply including/excluding safety stock in Customizing, in the Safety stock field, you can define whether the system is to base the calculation for the number of days on the safety stock level or the physical stock level.
If the number of days is based on the safety stock, which is set in the standard settings, the system calculates the number of days until the stock level falls below the safety stock level. If the number of days is based on the physical stock level, the system calculates the number of days until the stock level falls below 0.
Materials with critical ranges of coverage are indicated by red traffic lights in the MRP list and the stock/requirements list. You can define how many days are considered to be critical.
Note
The days' supply is not calculated, if:
Current plant stock is negative, or if
Current plant stock cannot cover the next requirement
Dependencies
You set the indicator for including the safety stock in Customizing for MRP or for Consumption-Based Planning in the IMG activity Define receipt elements for days' supply calculation.
Example
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
First receipt days' supply
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.
Additionally, in Customizing for MRP, you can use the safety stock indicator to define whether the number of days refers to the safety stock or the actual physical stock.
If the number of days is based on the safety stock, which is set in the standard settings, the system calculates the number of days until the stock level falls below the safety stock level. If the number of days is based on the physical stock level, the system calculates the number of days until the stock level falls below 0.
Material with critical ranges of coverage are indicated by red traffic lights in the MRP list and the stock/requirements list. You can define how many days are considered to be critical.
Note
The receipt days' supply is not calculated, if current plant stock is negative.
The receipt days' supply is calculated for a negative plant stock, if the next requirement is in the past.
Dependencies
You can define which receipts the system includes in both receipt days' supply and set the indicator for safety stock in Customizing for MRP, or for Consumption-Based Planning, by choosing the activity Define Receipt Elements for Receipt Days' Supply.
Example
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.

Requirement for 120 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
2nd receipt days' supply
You can use the second receipt days' supply to separate less binding and binding receipt elements.
For example, you can specify that the less binding receipt elements are taken into consideration for the first receipt days' supply, and only the binding receipt elements, such as production orders and shipping notifications, are taken into consideration for the second receipt days' supply.
Materials with critical ranges of coverage are indicated by red traffic lights in the MRP list and the stock/requirements list. You can define how many days are considered to be critical.
Dependencies
You define the receipts that are taken into consideration for receipt days' supply 1 and 2 on a plant-specific basis, in Customizing for MRP or for Consumption-Based Planning, under IMG activity Define Receipt Elements for Receipt Days' Supply.
Example
Calculation of the range of coverage: Starting from the current plant stock, the receipts are added one after the other on a daily basis along the time axis, and the requirements are deducted one after the other, 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
Purchase orders are included in the days' supply, but not purchase requisitions
1st day: Purchase order for 50 pcs => Stock = 290 pcs
Requirement for 90 pcs => Stock = 200 pcs
2nd day: Purchase requisition for 80 pcs => Stock = 200 pcs (remains)
Requirement for 120 pcs => Stock = 80 pcs
3rd day: Requirement for 100 pcs => Shortage
Range of coverage = 3 workdays minus 1 + 80/100
= 2 + 0,8

Stock Days' Supply Without Receipts - Negative despite ample stock?

I am reviewing the MRP list for a material and find the following situation in MD06 as well as the stock / requirements list:
SEALING WASHER;                                             3.0-     3.0-     3.0-     22.02.2011     216,071      PC     25,000
Where the values are StckDS, 1st RDS, 2nd RDS, MRP date, plant stock, UOM and safety stock respectively.
The plan situation considering only requirements and stock is as follows:
22.02.2011     Stock                                                                                216,071

With more than enough stock to cover all current and future requirements, why would the stock days' supply go negative? I do not understand the calculation from the online help, where negative values are not explained.
Edited by: Sriram N A on Feb 23, 2011 11:33 AM

I overlooked th fact that there was a separate "project stock" segment that was being planned, for which the requirement was past due. Hence the days' supply was negative.
The coverage for use of normal unrestricted stock would be 999 as per the data.

CTM - Safety days Supply

Hello all,
I'm working with CTM and I found a problem that I can't solve. If I set the profile to consider for example 8 safety days supply (I tested with all settings) the system do not consider the safety days of supply for the first 9 days. The system creates the supply with no difference between demand and supply and at the 10th day it start to create supply with 8 days difference from demand. Did anyone know what is happening? I tryed with fixed and time-dependent safety days of supply and I'm working with the SCM 5.0.
Thanks in advance,
Marcelo

Thanks a lot for your help.
This setting seems to be a very good suggestion. The early demand fulfillment specifies the time that the system have to build up safety stock, but I tested it and this setting seems that doesn't work for safety days of supply. Do you know if there is another setting like this for the days of supply?

Safety days supply not followed due to change in Means of Transport in SNP

Hello All,
I am facing a strange issue regarding the SNP heuristics and means of transport. We observed that the system was not respecting the safety days supply. For example if we had a receipt in bucket 'N' and there is a violation of safety days supply in bucket 'N-1'. When we un a heuristic ideally system should delete the receipt in bucket 'N' and create a new one in bucket 'N-1'.
But we observed that the system is retaining the existing receipt in bucket 'N' and also creating a new one in bucket 'N-1'. This is making the available days supply to increase manyfolds and the whole plan looks inconsistent from Safety Days point of view.
After analyzing the issue i observed that if we have existing receipts using a Means of Transport 'X'. Now if we run the heuristic using a Means of Transport 'Y' then the system doesnt touch the existing receipts. If I run teh heuristics using the existing Mean of Transport then it works absolutely fine.
Kindly suggest.
Regards,
Abhi

Hi,
when you check all products flag it means the means of transport is available for all products and not product specific, to select the MOT for SNP you need to check the aggrgtd plng flag.
Also safety stock has nothing to do with MOT, SNP heuristic plans based on checks the quota arrangement if its for multiple MOT it will distribute the PR based on the ratio in quota if both MOT are able to meet demand on time, otherwise it will violate quota till the time both MOT are not capable of meeting the demand on time.
If no quota is defined it will check for which lane is able to meet on time n if their are multiple lanes which can fulfill demand on time then it will choose MOT with less cost.
Have you got multiple MOT for a source destination combination to be considered for SNP heuristic?
Just check your design again and explain the problem again as this is not the standard expected behavior.
Thanks,
Sanjog

Fixed Days Supply & Fixed Order Quantity

Hi,
in certain cases we use the Fixed Days Supply & Fixed Order Quantity attributes in the Item Master to influence our ASCP plan calculation (size of planned orders etc.)
We need this because we do discrete production (semiconductor industry) and with the fixed order quantity we to ensure that the system plans with full Lots.
However I am not sure what the impact of the Fixed Days Supply is, especially in combination with the Fixed Order Quantity.
Unfortunatly the Manuals do not tell very much about this. Does anyone have experience with this and wants to share some knowledge? I would like to know what these parameters really do and maybe there are better ways for our setup...
Thanks,
David.

Hi,
thanks for the reply. I found the detailed explanation in user guide you mentioned.
I am not sure that we made the setup in an optimum way.
We use for example fixed days supply = 5 for many buy items, because we place weekly Purchase Orders for these items and want to have the planned orders combined instead of having a planned order for every day.
And we use the fixed order quantity to prevent two things:
1) The size of the planned order gets below a typicall Lot size and the calculated leadtime for this planned order is too short. We define item based resource usage rates so it will calculate the exact lead time for the small planned order, but in reality our production has to run the full Lot which takes more time of course.
2) without the fixed order quantity the planned orders might become too big, which makes scheduling of them more difficult, because finding a free time-slot on the machines for a huge quantity must be more difficult than for a smaller planned order.
But unfortunatly Oracle does not provide some business cases, especially for our semiconductor industry so it is more trial-and-error what we are doing...
regards,
David.

Use of Calendar in Days Supply Calculation in APO

The Days Supply is R/3 is defined as - The range of coverage is then the number of workdays between todayu2019s date and the date of the requirement that causes the shortage minus one day
The Days of Supply in APO defined as - The days' supply tells the planner how many calendar days the receipts and stocks will cover the current requirements for.
In our case we have a factory defined in R/3 as 5 days working, so R/3 display Days Supply it displays only number of Working days till stock/receipt last while APO displays number of Calendar Days ( including non working days)
Is there any way..i can make these 2 number same in R/3 and APO. Both System has same configuration for considering stock, receipt 7 requirement elements.
Thanks in advance !!!

Hi,
Normally APO should consider the working days.
could you check that the macro "Determine workdays" is properly executed; and that "Days' supply " is based on the workdays key figure.
Please note that by default the relevant calendar is the shipping calendar; please ensure that it is maintained in the location master.
If you want to based it on another calendar, you need to adapt the macro.
Thanks and Regards

Can't Find the fixed days supply in the collected items.

Dear All,
after running the collection process , i can't find the fixed days supply item attribute in the collected data (from the table MSC_SYSTEM_ITEMS).
Regards.
Ahmad.

Ensure that you have defined fixed_days_supply at the org-item level.
If you have, then check if the collection is working properly by making some other change to an item (such as description change and change of the fixed lot multiplier).
If those changes are not coming over, the problem may be with your Data collection. Can you run a full DC? Make sure that the snapshots have been refreshed properly.
Hope this helps,

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

Fixed Days Supply - Weekly Buckets

In 12.06 for Unconstrained Planning we are using the Order Modifier "Fixed Days Supply" .Also when using Fixed Days Supply Modifier we are not using any other order modifiers.
The issue is Planning process does not consider the Fixed Days Supply value for weekly buckets.
If the Fixed Days Supply value is 5 days for Item at Org the planned orders are are created in weekly buckets for every 2 weeks.
For the Days bucket the Fixed days supply order modifier works ok.
Tried changing the profile option : MSC: Apply Lot Modifiers in Weekly/Period Buckets to YES without any .
Any idea why the planning engine is doing this?

When you use aggrregated time buckets (weekly in this case) plannign engine shifts the due dates of the demand falling in a particular bucket to the end date of that bucket. (for eg...demand of 100 nos of a finished good on day 2 of 2nd week will be shifted to last day of week 2nd week). So leadtime offsetting starts from the end date of the bucket and not from the actual demand date. This can result in shifting of planned order supply to a date that is beyond the timespan governed by "fixed days supply". (5 days in this case).Being so this supply will not be used while deciding planned order qty.
This is one possible reason.....pls check this out.

Utkarsh
