Lot size (materials planning)

Dear All
Pl explain me in details Concept of Lot size and its relavance in Planing of material
Regards
Manoj

Hi,
MRP will firstly determine the EXACT qty required.
It then looks at the Lot size indicator on the material to see what should actually be ordered / produced.
You might indicate an "exact" lot size, in which case it does just that, it tries to procure the exact amount it has determined.
You might want the system to replenish up to maximum stock and so the lot size would cause the exact requirement to be change to the qty to bring the stock up to the maximum qty.
You might want the system to bundle together the requirements over X days, weeks or months etc. and so produce one large requirement instead of one for each.
You can even get the system to determine if it is cheaper to have large stocks and few PO charges or more frequent POs and so cheaper storage costs.
there are lost of lots sizes and they all try to bring in sensible quantities, instead of just what is immediately required.

  • Select BOM as per lot size against planned quantity

    Dear all
                  i hav prob. releated select BOM as per lot size against planned quantity , suppose i hav monthly plnned order for
    1000 nos. quantity and having two alternative BOMs like lot size 0 to 500 and 0 to 200 , so after MRP run system should create planned order(inhouse prod.) as per lot size i.e. 500 x1 and 200x 2 ., how is it possible please guide me .
    thankx in advanced

    create a two production version , if the plan quantity is more than 200 system will take the Alternative BOM  and take the BOM ( 0-500 ) otherwise system will take the BOm ( lotsize 0-200).
    Or
    Create a Production version, Manually change the PV as per your requirement , And  rerun MRP with delete a recreate option

  • Planned order with Lot size and Planning Calendar in MRP

    Hi All
    I request your help in understanding MRP results in below mentioned scenario:

    Lot size: Z1 (this is copy of PK with Period Start = Start Date)
    Safety Days Time: 3
    Safety time indicator: 2
    In house Production time: 1
    I am running MRP with
    NETCH
    Planning mode: 3 (Delete and recreate planning)

    I am executing MRP on 7.04.11
    As shown above the, can you please explain why the planned order is on Wed 12th and it covers 5 days requirement and similarly Tuesday 19th and covers 6 days.
    I am not able to relate the relation between Planning calendar and Lot size procedure used. Also what would happen if I make planning calendar valid for two days in a week.
    Thanks in advance
    Rahul

    Thanks dear
    Yes you are right the Planning Calendar starts 18.4.11 and ends 24.4.11
    Now as far as first planned order is concerned I thought it should be scheduled to start&end  on Monday 11.04.11, rather it starts&ends on Tuesday 12.4.11. Also the actual coverage days goes up to 5 days even though its maintained for 3 days.
    Similarly the second planned order also comes up on Tuesday 19.04.11 and covers 6 days (more than the setting and planning Calendar of only Monday)
    On the whole this is confusing me on Lot size and Planning Calendar relation and how it impacts MRP. Can you please help me on this.
    Also if you can throw some details on: how to restrict MRP to give planned order only on, say, Monday and Thursday, as only then it could be produced.
    Thanks in advance

  • MPS Lot size rounding

    Hi,
    We have following scenario:
    1) FG X with planning strategy 11, MRP Type: M0, Fix Lot Size: 100 Box
    2) PIR entered for FG X for 100 box.
    3) MPS Run
    4) Plan Order of 100 box created
    5) Convert to Production Order and final confirmation of op 10 for 90 box.
    6) Production Order appeared as receipt element as 90 box.
    6) In next MPS Run, Plan Order of 100 box being triggered for the FG X again to cater for the outstanding requirement of 10 box.
    The client do not want the Plan Order of 100 boxed to be generated again. the stock initial GR of 90 box is deem to be able to cater for the market. In generak if the requirement is less then the batch size (fix lot size), no plan order should be created.
    Appreciate if you have any idea/solution that can overcome the above requirement, kindly share with us..
    Thanks.
    WH. ONG.

    Hi Wan Haur Ong,
    Well i gone through with your thread and i am having an idea for your requirement.
    As you said that you want only for particularly the the remaining quantity like 10 boxes should have a production., It means only for 10 boxes:
    I would like to suggest you there is a funcationality called rework process for that you have to use funcationality called Trigger point for that particular operation:
    Please maintain these steps for that operation OK:
    First check in Tcode OPJF for the selection id a Priority is defined for the Task list type S with usage 1 and status 4 and then Proceed as follows:
    1. Create a Reference op set in tcode Ca11.
    Enter the plant,Description , usage and status for the ref op set Enter lotsize and unit of measure.
    Enter the op as 0010 / workcenter/op control key/Description for the op Enter the standard values and save.
    2. Create a Standard trigger point in CO31.(Ex Production)
    Enter the Trigger Point usage /Group as FERT.
    3. Tick the Trigger Point Functions.
    4. Enable the indicator create order with Reference.
    5. Enter the system status as PCNF.
    6. Enter change as +.
    7. Enable the indicator once.
    8 . Now place the cursor on the create order with reference.
    9. Goto Parameters.
    10. In the Parameter enter in the group the created Reference op set group no.
    11. Order type as PP01 and group counter as 1 and save the Trigger Point.
    12. Now goto the Routing for your Material.
    13. Choose the last op to assign the Trigger point.
    14. Select the OP -
    > Goto ---> Trigger Point overview.
    15. Enter the Trigger Point usage as FERT.
    16. Now choose that line ,select the Details---> Trigger Point f7. The system will says standard trigger point exists from which you can select the created Trigger Point (EXx Production)and save.
    18. MD02/MD04.
    19. Convert the Planned Order into Production Order and Release the order.
    20. Now confirm th ops.
    21. For the last op enter the yield and rework qty and set the status as PCNF.
    22. If the status of last op is PCNF then in the system a POP UP will appear as Activited by Trigger Point /Create order with reference/order number/sequence and op number which trigger point works and enter.
    I hope it will helps you, please get back to me if you have any questions OK pop me again.

  • Lot size exclusion from planning run

    Hi Gurus
                   My scenario is some materials are maintained with lot sizes as EX , VB, HB ,  when planning run executed , the system should not consider the VB and HB lot sizes ( these are not bom components) and no procurement proposal should exist , we are not following storage location MRP ,
    Pl come back in full thanks in advance
    Regards
    Ram

    Hi ramki
    VB is MRP type not lot size. VB consumption based planning with manual reorder point. The planning proposal will be created based on your reorder level.
    HB is lot size of " Replinishment to maximum lot size "
    Normally oils and others are procured where the storage tank capacity is restricted. The max replish level will be your max tank capacity.  You can define them as cosumable materials or bulk materials.

  • Fixed lot size key has no effect on planned orders generated for VC PIRu2019s

    Hello gurus,
    does anyone have an idea why the fixed lot size key is not having an effect on the planned orders that are generated for the Planned Independent Requirements (PIR) for MTO configurable materials. My client is using planning strategy 56.
    I have copied & customized the Fixed lot size key FX to suit the MTO production (u201CLot size as in short-term periodu201D activated) that works nicely even with configurable materials when a planned order is generated for a sales order. But the planned orders in the preplanning segment, i.e. that were generated for PIR's, are still created equally to the PIR quantity.
    Is this behavior an error or an SAP feature? Though, I have reviewed the OSS Note 437098 that might be related to this. Can anyone tell me if it is related to this issue?
    Regards,
    Mikko

    Got the answer fro SAP:
    Please consider the following note, which provides the explanation about this behavior of the lot-size, when VSE requirements are used:
    125498 - MRP/Docu: Planning segment and lot-for-lot order quantity
    The following section of the note describes your scenario in detail:
    "The planned independent requirements for a material are in a separate
    planning segment (planning strategy planning without final assembly,
    requirements type VSE, VSEV).
    You enter a rounding value or a rounding profile or an lot size that is
    not exact in the material master.
    Material Requirements Planning:
    In Material Requirements Planning, planned orders are generated for the
    planned independent requirements. The lot size settings (such as fixed
    lot size or minimum lot size) are also not taken into account."

  • Sequence dependent lot-size planning as a basis for PP/DS blocks?

    Hi ,
    I consider the following system setup for a Mill Products planning implementation .
    1) In SNP one performs SOP planning with common goals to adjust sales plan, establish equipment maintenance plan, transportation plan, etc. The first month of the SNP plan is supposed to be in daily buckets. Using the SNP optimizer is a good option since the business goal is to use equipment more efficiently, let's say to minimize setup costs, and there are warehouse limitations for semifinished products as well.
    2) In PP/DS we are going to use CDP and block planning since it is the best practice.
    3) SNP planned orders can be used as a basis for PP/DS blocks on the resource, upon the condition that the configuration of SNP product - kmat variant and block requirements match.
    In SNP i  see that the SNP PDS has a duration of 1 day (that's fine), but the sequence dependent lot-size planning requires a bucket of at least 1 week long (1 month in my case) since the SNP orders are sequence-optimized only inside of one bucket. The result of such an optimization are additional counters assigned to SNP orders according to their sequence  minimizing setup costs. However, orders are not scheduled according to the sequence.
    So far it looks like such a combination is not useful as
    - Orders in monthly buckets are not scheduled on days and cannot serve as a basis for block dates proposal for PP/DS block planning.
    - If a product production volume is less than 1 day, SNP cannot create any more detailed block in principle since the minimal time bucket is daily bucket.
    I searched over forums on these or similar topics, however no definitive answer so far for the question in the subj.
    Could anyone bring more  light on this ? Maybe I am missing something in the setup or sequence dependent lot size planning was designed for other purposes/industries?
    Best regards
    Vladimir

    Hello Asim,
    Issue one
    in product selection for propagation range you can set your selection criteria which selects the products dynamically. You just have to change your report variants for planning run. Do I misunderstand your concerns?
    Issue two
    Changing to planning procedure 1 will not delete the PFE but will prevent APO to create a new entry after any MRP-relevant changes happen or heuristic SAP_PP_020 (which creates the initial entry and does the low level code determination) is run.
    In some cases procedure 1 will still create a PFE. Please check customizing for details. Thats why I would recommend to create a new planning procedure with "no reactions".
    As soon as you prevent APO from creating new PFEs you can just once delete the PFEs in /SAPAPO/NETCH by just setting the first column for these materials blank (select your materials, mark column, delete indicator).
    Corresponding table to MDVM is /SAPAPO/PEGKEY. Indicator for PP/DS is NETCH_RRP.
    If material is not planned in APO you do not need a PFE in APO.
    Issue 3
    Maybe utilize table /SAPAP/PEGKEY
    As I said if you prevent creating the entry you just have to delete (set indicator blank) once.
    Hope that helps.

    Uli

  • PLANNING CALENDER IN LOT SIZE

    Hi
    What is the function of Planning Calender in Lot Sizing procedure in SNP.

    Hi
    You can define the planning calendar to define the periodicity of lot size.
    For example in our case we want to SNP to create requirement only in alternate month based on lot size.
    So we create planning calendar which consist only alternate month and attach to lot size.
    Now when we execute the SNP planning, it will create supply element only in alternate month.
    I hope this will give insight of it. Please let us know , if it helps you.
    Thanks

  • Help on Planning Calender and lot size procedure settings

    Hi Gurus,
    We have 2 different schedule at the moment for our PO Placing to our supplier :

    2. Planning Calendar D02 --> For Airfreight shipment, PO Placing on weekly basis, every Friday and RDD (Request Delivery Date) is on Wednesday (5 days after PO Placing)
    Now we have required to change the SEAFREIGHT process by having the PO Placing on weekly basis, every Monday and RDD (Request Delivery Date) is on Wednesday (9 days after PO Placing).
    Please let me know the step by step procedure to create a new Planning Calendar and Lot Size Procedure to accomodate this requirement?
    Thanks for your help.
    Regards
    Brijesh

    Dear Brijesh:
    1. I think you are planning to change the Planning calendare D01.
    2. For this go to MD26- GIVE THE plant / palnning calendar id.
    3. Then in the CAlc rule for spec peroid - change the day from wednesday to Monday.
    4. SAve this and generate periods.
    5. Now in the maeterial master- check if you have the lot size as PK and also planning calendar as d01.
    6. In the planned dleiveyr times you enter 9 days.
    Kindly check this and revert back.

  • Lot size key HB with a planning calendar

    I would like to be able to continue to use lot size key HB (replenish to maximum stock level), but with a planning calendar in order to specify Friday deliveries.  However, the system does not appear to be capable of doing this.  Does anyone know a way around the system limitation?
    Thanks in advance!

    I appreciate the suggestions.  I would very much like to use a "Friday" planning calendar, however, if I changed the lot size key to PK - I can no longer replenish to a maximum stock level (unless someone knows of a way to get MRP behavior like lot size key HB but with something like PK).
    I also tried using the "Planning cycle" field on the MRP 1 screen, but it appears to require time-phased planning - which again seems to rule out use of Lot size key HB.
    Any other ideas?
    Thanks again,
    Ed

  • MRP planning Purchase REQ per fixed lot size

    Folks,
    I have materials which have MRP type PD with fixed lot size of 20 pieces. Safety stock = 200 pieces. MRP run results in 10 preqs of 20 pieces each. I would like to have 1 Preq of 200 pieces. How can this be achieved?
    Regards,
    MdZ

    Hi,
    This is because of Lot size "FX" you maintained as 20.
    For FX lot size system will divide the total qty as per the fixed lot qty & throw that much of PR for that stock.
    So Safety stock = 200, FX =20 so PR will be 200/20 = 10 PRs
    If you want 1 PR for your safety stock, then change the Lot size to "EX" then system will throw 1 PR for 200 qty as per your Safety stock

  • Planning time fence and Lot size

    Hi,
    MRP type=P3, Planning time fence=28 days, lot sizs=EX and all 28 days are working days.
    so today =05/112009 and i check the MD04 End of planning time fence is 03/12/2009
    But when i change the lot size to =ZC(3 Months lot size) keeping the rest all same as above.
    and when i check MD04 The planning time fence moved to 01/01/2010
    What should be done to keep the planning time fence as 03/12/2009 and i don not want to change either MRP Type or lot size

    I think your Lotsize Indicator is based on Planning Calendar. Please check the period definations of the planning calendar assigned to the material in the MRP2 view.

  • CTM Planning: How to Handle Min Lot Size Daily Resource Capacity?

    Hello,
    I am facing a situation where the Min Lot Size values require more than a days capacity of the Resource.
    Finite Planning CTM is skipping all demands.
    Example:
    Daily Resource Availability = 24 Hrs,
    Capacity Consumption per PPM = 1000 Kgs / 1 Hour.
    Min Lot Size =  50,000 Kgs
    Capacity requirement for the 50,000 Kgs = 50 Hrs
    Is there a way CTM can plan this?
    Thanks,
    Ran

    Yes the time buckets in CTM profile has nothing to do with this limitation...
    Nor does the infinite/finite setting.
    Basically its a limitation of how the resources are stored in livecache.
    You can not exceed the capacity for which the resource is stored...
    The only workaround is to define the resourcde in weekly time buckets by manually defining a capacity profile.
    I don't like this as every order will take a week...
    I am not aware of any other workaround...
    I have seen other clients take out the minimum lot size for SNP, then when cif transfer the order back to R/3, it is combined to 1 large order...

  • Lot Sizes Used for Fore cast planning

    Dear all,
    <b>For fore cast planing and Automatic reorder point planning what are the lot sizes are use full and what are the advantages and effects  for each lot size procedure.</b>
    I am expecting answer for this question from all of you.
    Regards,
    Krishna

    Hi
    These fore cast planing and Automatic reorder point types are consumption based planning.
    Hence for  these MRP types normally, lot for lot ( EX ) will be used.
    You can go through the following link for further info on lot sizing procedures.

  • Reorder Level Planning with Min. Lot Size

    Hi All,
    I am trying to configure MRP Run. I am maintaining following Data
    1. Reorder Level
    2. Maximum Stock Level ( stock beyond which PR cannot be raised or stock cannot be maintained.
    3. Min Lot size (lot size of which PR should be raised.
    can anybody please help.

    Hi
    Max.stock level can be use with lotsize HB not with VB. But you can use max.stock level and minimum lot size with reorder point planning.
    Ex. Reorder point -10
    Max. stock level - 20
    Stock -9
    When the stock level goes below 10, system will create a P.R to topup the stock value for 20.
    Ex. Reorder point -10
    Min.lot size - 5
    Stock value - 9
    When the stock level goes below 10 ie, 9 , system will create a P.R to topup the reorder point. But the min lot size is 5. So P.R will generate with quantity 5.
