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.

Fixed Order Quantity

Hi,
we are using ASCP together with SFM. We do descrete manufacturing for our products. The products flows look like this:
- asssembly item A (finished good item)
=> is make item (has routing), uses component3
- component3 is make item, uses component2
- component2 is make item, uses component1
- component 1 is buy item
So the flow of material looks like this:
component1 -> component2 -> component3 -> assembly4
(buy) (make) (make) (make)
In production we typically process only full Lots/Batches with a certain quantity depending on the component1.
We want that ASCP plans always full Lots, because the leadtime of the full Lot is always needed in reality. If ASCP plans with partial quantities, then the estimated/calculated leadtime for the planned orders will not be realistic.
To achieve this we want to use the Fixed Order Quantities, however it turned out that we run into several other problems if we use this parameter. For example it happens that system recommends to buy material (component1) just for the sake of the fixed order quantities.
We are running into issues if we enter the Fixed Order quantities, and we get other issues if we leave this empty.
I am looking for someone who has experience with this parameter and can give some recommendations. Maybe we use the wrong approach and there are other paramters that we should use to achieve what we want.
Big Thanks in advance,
David.

Sub: "We want that ASCP plans always full Lots, because the leadtime of the full Lot is always needed in reality. If ASCP plans with partial quantities, then the estimated/calculated leadtime for the planned orders will not be realistic."
Oracle ASPC has some more meaningfull logic in Lead time calcualtion. It is not that Lead time will be wrong when you Process the low batch. On the other hand lead time goes up when you use Fixed order Quantity , irrespective of Demand. It also files up your inventory.
See for example, If you have fixed order quanitity for an item say 1000 numbers;assume that you have on hand for 500. and need to refill balance 500.
What will ASCP recommend you ?..1000 numbers.It files your invenotry...Does this mean that lead time for producing 1000 is less as compared to 500!!! also is it acceptable to produce extra 500..
.It also make you to plan low levels adversly with case cade effect...
You issue is not lead time...You are talking about setup time. If you produce more batches, you are occuring the more setups for same items. it makes lead time more lengthy considering the setup time. This is your problem and wanted to limit this or wanted to make it optimization. (Is it right my observation of your problem??)
How to control...?. Rather than speaking about lead time , let us talk in other way ...what is the Planning perid do you want want to conisder while planning a batch or lot size?. In other words let us take an example,,,
Component2 has a lead time of say 30 days for 1000 numbers. At the same time, I am able to accamadate only max 1000 numbers. If the demand goes up ,say for example, 2000, then I need to have two batches. If the goes less than 1000 and demand split in time gap ...for exmaple, 500 in first of week of may and 200 in last of week of may, still I want to consolidate 500+200 into one batch and want to Plan 700 as it is less that 1000.
If the above condition matches..you need to use Min Order/Max orde qunatity and Fixed days supply together. This is the wonderful way it controls the objective as stated above.In this example you will set min 1 , max 1000 and fixed days supply to 20 days.
How ever in some cases if the demand comes likes this, say for exmaple 2000 and 2000, then there is a recommendation to produce 1000,1000,1000,1000 with due date as equal to first lot. However, if you use constranied based planning, APS will reshdule and give you best possible time slot. Other wise, if there is enoguh capacity you are still able to produce 4 batches in first due date. The result of this behaviour depends on EDD and ECC and will vary.Make it understand this and do test case..go ahead..
Thanking you,

Scheduling Agreement - Fixed Order Quantity

Hi Experts!
For a short time we work with scheduling agreements in our company. So far it work well, but know i have a question, maybe anyone of you can help me with my issue.
We would order always the same fixed order quantitiy, i know that i can do this in the material master, but we still have more than one vendor for one material. So i can´t maintain the fixed order quantitiy in the material master.
Does anyone have a idea, how i can handle this? Maybe in the inforecord, but the MRP doesn´t consinder the values in the inforecord.
Best Regards
Florian

Hi,
Use CDHDR and CDPOS tables.
Goto VA33 or VA32. In menu Click on environment choose changes.
Enter agreement number and execute. select the line click on choose button. you will get details.

New lot-sizing procedure (similar FX fixed order quantity)

Dear All,
I have to create a new lot sizing procedure for MRP run. This new procedure should be similar to FX - the material should be included in MRP run when the stock falls below reorder point - but the quantity ordered (proposed to be ordered in PReq) should be the fixed lot size no matter which is the difference between the reorder point and the stock.
To clarify the request: the reorder point is 70, the stock level is 15 and the fixed lot size is 25. The MRP run should create 1 PReq for 25. (The standard functionality of FX lot sizing creates 3 PReq for 25 pieces each one - because the needed quantity is 55.)
If there is no standard customization to be done, I think I should do some changes in the needed quantity (set the quantity 25 instead of 55) - but I need yours advice also about the best way to do this. Maybe you may indicate an exit/BADI or a place where I can do an enhancement to achieve this.
I now it is not the best request - but I have to do it, unfortunately .
Regards,
Florina R.

Hi Tomasz,
1) The reorder point is 70 (greater than the needed quantity for a week) because the vendor has some delivery problems and also because this quantity covers the delivery lead time.
2) The lot size is fixed because they do not want to order more than the needed quantity for a week even if the difference between the reorder point and the stock level is greater than 25.
I'm able to fix the lot size but not to limit the quantity at this value (25).
I have to do this because they will provide the needed quantity (if the stock falls to 0) from another vendor (but the tricky thing and wrong also is the fact that for the second vendor I have a second material....).
It is hard for me to convince you that the request is correct because I know in this way SAP will work incorrectly - but the client knows the consequences and even so wants this kind of lot sizing procedure...
Regards,
Florina R.

Fixed Days Supply , Oracle E-Business Suite Planning

Dear Sir/Madam,
With regard to using fixed days supply on item attribute level, we are not yet sure what the effect is on the planning.
We know that demand over a certain period of time (FDS) will be aggegrated to one orderline.
However, if in week 10, demand has been aggegrated for let say quantity 10, and during that week (and thus in the weekly MRP RUN), additional demand of 2 in that same timeframe is needed.
Will Oracle include that extra demand and make one orderline for 12?
We currently think that FDS frames are frozen after one MRP Run. is this true, and can this be ignored?
What I mean is:
For item XB we have the following planned orders
-5 need by date 10-03-2015
-7 Need by date 10-06-2015
-10 need by date 10-08-2015
If we set FDS to 365 days, for item XB, Oracle will aggregate total demand of 22 in one orderline.
But what happens if suddenly a new planned order enters O_MRP
3 need by date 08-08-2015?
Will the planning , unless we haven't released the orderline of 22, make a new orderline for 25 units for need by date 10-03? We currently think it generates a rush order.
Many thanks in advance!

The short answer is probably.
The long answer:
- You have mentioned a certification and then referred to it as a "course".
- To achieve certification you need to pass two exams: (Ref: Oracle EBS R12 Advanced Supply Chain Planning Certified Expert Consultant )
- Associated training courses are recommended ... though not mandatory in this case ( See recommended training on exams from the above link).
- It is almost certain that whatever training one undertakes that should increase knowledge ... and if job relevant it should help you get your job.
- You will need to look at exam topics (or training course topics) and make a self assessment of how much you stand to gain; and how much it will gain it in future.
---- You should know more about yourself than anyone else, and if you are honest with yourself should be able to work out your own cost/risk/benefit.
------ Remember cost may not only be monetary ... it may be time you could have spent doing something else ... perhaps with your family.

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.

Fix date/Quantity in the sales order schedule line

Dear SD Gurus,
When we select the fix date/quantity in the lsaes order item schedule line, what happen? Hhow does it imapact the MD04,V_V2 and can this item be seen in CO06 to change the item date manually?
Thanks
J.Black

With fix/date and qty, you can't use rescheduling and back order processing. The setting assumes that you want to fix the date at the time of initial confirmation and therefore these functions are not relevant, and ignore anything with fix/date and qty. If you want to use those functions then don't use fix/date and qty.

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,

Return Order Quantity as Fixed / Planned Receipt in MD04

HI
Can anyone guide me to configure to show Return Sale Order Quantity as Planned or Fixed Receipts in MD04 transaction.
Thanks

The MRP controller uses the display function (MD04) to review both MRP lists and stock requirements list to analyze the requirements and decide on a course of action (company designates an individual as a MRP controller and MRP controller is indicated in Material Master record).
It enables the MRP controller to process the requirements and make informed decisions to change and/or approve purchase requisitions and stock transport orders thus triggering the acquiring of materials.
Your material is returnable packing material. The material is available and does not require MRP planning. There is also no need to trigger a requirement to procure the material. Hence this return does not show up in MD04 list.

Fixed Purchase Order quantity with manual PO creation??

Hi,
Is there any way to define a fixed PO quantity on the inforecord or the material master and have SAP automatically insert this quantity on the PO. I know it is possible to have SAP determine the vendor from e.g. a quota arrangement set-up and have this inserted automatically, when source determination is flagged, but how about the PO quantity.
Note that we do not use SAP for MRP planning, so we create a manual PO and enters all data on the PO manually including the PO quantity, but I assume there must be a way to have this quantity inserted automatically if it is maintained on the info record or material master. However if I enter a fixed quantity on either one of these it seems that it only works in relation to MRP planning, where SAP will then account for the fixed quantity.
br,
Jannik

Best to achieve this is to use the copy functionality. Advise your users to create POs by copying from existing POs. This will ensure that the PO quantity is copied also, then the users can change whatever needs to be changed.

Fixed operation Quantity- Execution factor

Dear All
SAP NOTE:
Use of Execution Factor
Use the execution factor to indicate how many times an operation or sub-operation is to be carried out during processing of an order.
The execution factor refers to the work, the operation duration, the operation quantity and the material quantity.
If the indicator fixed operation quantity was set, the execution factor has no effect. If the indicator fixed lot was set, the material quantity remains unchanged.
Where i can find Fixed operation quantity and fixed lot indicator field in project builder.
Thanks
Shobana

Please refer this SAP link:
http://help.sap.com/saphelp_erp2005/helpdata/en/0f/28b904c3e511d194f900a0c93033d8/frameset.htm
i.e.
If the indicator Fixed lot quantity is set (in the component item under General data), the execution factor of the components is not taken into account for the component quantity.
If the indicator Fixed op.quantity is set (on the external processing screen of the operation), the execution factor is not taken into account.
Hope this will help you.

Fixed Scrap Quantity In Production

Im using SAP ECC 6.0 now.
Is there any place I can set a fixed scrap quantity in BOM or PP related?
The situation is like this: While producing Semi-finishegoods A we alway need extra 10 Raw-mateiral B for scrap.
That means 100 A needs 110 B ; 10 A needs 20 B;
How can I configure it so that when I create the procution Order for 10 A, it will put 20 B in the components automatically;
I can only find scrap ratio in percentage.
thanks alot for looking into my problem.
Edited by: Liang Shi on Aug 25, 2010 7:08 AM

Hi
As you rightly mentioned , to my knowledge, as of now in standard SAP
All the SCRAPS are maintained in % only.
1) Component Scrap >>>>> Maintained in MRP4 in % & also in BOM General data tab
2) Assembly Scrap >>>>>> Maintained in MRP1 in %
3) Operation Scrap >>>>>>Maintained in BOM item detail General Tab in %

Fixed order of photos for album w/o sorting

When importing photos, PSE (by default) imports using a LIFO (Last In First Out) method - hence photos are in choronological order from last to first taken. If photos are from, say, a vacation, this is a problem since nobody wants to see their vacation photos in reverse order.
This can be rectified by Sorting: Date (Oldest First).
However, this sorts the entire Catalog.
My question is: is there any way to use this Sort: Date (Oldest First) and then to assign a Fixed Order to the photos in the album so that I will not have to go through this each time I view the album.
I realize that I can arrange the photos manually, however, in the example I am thinking of there are over 2k photos.
Thanks,

Tom,
Since you used the term "Album" I suspect that you are using PS Elements version 6 or 7. (for future reference it is better to include the version number of PSE when you post because sometimes it makes a difference)
I think that this will work for you, but I am not currently in a place where I can verfiy it: -
After you have created the Album, Right click on the NAME of the Album in the pane on the right and there should be a choice for
b Chronological Sequence
in that menu.
If your photos are all from the same camera, then that should give you the sequence you want. If your photos are from multiple cameras, then your results will be influenced by whether both cameras time stamps were the same (or very close). If you do have multiple cameras, you can use the Organizer Date/Time change adjustment commands to bring the times closer in sync.
