Inventory control for waffer/die in substrate fabrication

Hello gurus,
Looking for advice for inventory control of substrate fabrication. Fundamentally, how do we configure SAP such that 1 piece of a component (wafer) may yield different QTY's of sub-assemblies (sliced die), and plan MRP at the wafer level?
We use a wafer, say W-1, that may be printed into different size die based on the pattern being dispensed. This affects the yield of the wafer- EX, we can yield 121 of D-1 and 242 of D-2 using 1 piece of W-1 based on the print of the die. My question is, how do we configure SAP to plan to order the correct QTY of W-1 with these requirements? We are not able to use a fractional QTY of the die BOM for the wafer (i.e. a die BOM to consume 1/121 wafer per W-1 die). We have heard of solutions using UoM conversion (where 1 die EA = 1 die Sq Inches, so 121 Sq. Inches = 1 Ea Wafer). I have also heard solutions for alternate BOMs based on lot sizing... could this apply here also?
(1) W-1 -> (121) D-1 -> (121) Assembly-1; Demand for 1,000 Assemlby 1
(1) W-1 -> (242) D-2 -> (242) Assembly-2; Demand for 6,000 Assembly 2
How to get SAP to plan to order ~34 W-1?
Using R/3 release 7.3
Regards,

Timothy,
If I understand your question correctly I think this is fairly straightforward scenario.  First establish the following BOMs
BOM 1
Assembly1                                    121 EA
                D-1                               121 EA
                                W-1                  1 EA
BOM 2
Assembly2                                    242 EA
                D-2                               242 EA
                                W-1                  1 EA
For Material “W-1” set the Rounding Value (in MRP1 view) to 1.000.
If you have demand for 1000 Assembly 1 and 6000 Assembly 2 then when you run MRP here’s what would happen:
1000 Assembly 1 requires 1000 D-1 which would require 8.264 (=1000/121) W-1, but with the Rounding Value for W-1 set at 1.000, that gets rounded up to 9.
Similarly, 6000 Assembly 2 requires 6000 D-2 which would require 25.793 (=6000/242) W-1, but with the Rounding Value for W-1 set at 1.000, that gets rounded up to 25.
Total requirements for W-1 = 9 + 25 = 34.
Hope that helps.

  • Inventory Control for Expendable Packaging

    Greetings!  I am trying to set up Expendable Packaging so that we can control inventory.  I added a new Item Category Group to use Item Category PO on Deliveries, and changed Packaging material to use this Group.
    It is now showing Goods-Issue when posted in a Delivery, which is what we wanted.
    However, it is also now showing up in the Invoice, which we do not want.
    I have set the Item Category to "Not Relevant for Billing", but it still shows up on the Invoice and then causes a problem for "Item Category LF PO can not be Invoiced with Billing Type F2". 
    I even tried to add PO to the copy control from Delivery LF to Invoice F2 - it can now Invoice, but we get a "pricing error" and it shows up in the EDI 810, which we definitely don't want.
    What is the secret to controlling packaging inventory but not having it appear on the Invoice?
    Thanks in advance.

  • Inventory control

    I want to know abt
    what material movement is? and the different types of material movement.
    what is stock initialization?
    in inventory controls..

    Hi........
    what material movement is?
    When you enter a goods movement, you must always enter the movement
    type. The movement type has important control functions in Inventor
    Management. It is essential for
    o updating the quantity fields
    o updating the stock and consumption accounts
    o selection of the fields used for entering documents
    o printing goods receipt/issue slips
    Below you will find a short description of the standard movement types.
    The reversal movement type is the movement type + 1 (reversal of 101 =
    102).
    101 Goods receipt for purchase order or order
    If the purchase order or order has not been assigned
    a stock type (unrestricted-use stock, stock in qualit
    blocked stock) can be entered during goods receipt.
    131 Goods receipt for run schedule header
    This movement type cannot be entered manually. It is generated
    automatically at notification of goods receipt for a run schedule
    header.
    261 Goods issue for an order
    This refers to all withdrawals for orders
    The goods issue can be posted manually in Inventory Management or
    automatically when an order is confirmed or via a delivery in
    Shipping.
    351 Goods issue for a stock transport order (without Shipping)
    643 Goods issue for a cross-company stock transport order (Shipping)
    Used only for cross-company stock transport orders with SD billing
    and invoice. The quantity is withdrawn from the unrestricted-use
    701 Inventory differences in unrestricted-use stock (MM-IM)
    This movement is generated automatically during inventory difference
    posting in Inventory Management.

  • 0IC_C03 Inventory Control Data Issue

    Dear Gurus,
    We have implemented BI 7.0 with the latest support package as of 1st May 2011. Issues are coming relavent to 0IC_C03 infocube for inventory control. I have followed the how to guideline but issues are there.
    I have done the following settings:
    1:To fill up the extractor for 2LIS_3_BX i have used the Transaction MCNB (All Stock Including non-valuated).
    2: To fill up the extractor for 2LIS_3_BF i have used the Transaction OLI1BW (Posting Date till 2999).
    3: To fill up the extractor for 2LIS_3_UM i have used the Transaction OLIZBW (Posting Date till 2999).
    4: To generate the IP for 2LIS_3_BX for the opening stock balances the update mode CREATE OPENING BALANCE is not showing so i have used the update mode Generate Initial Status.
    5: After running the IP for 2LIS_3_BX i run the DTP with extraction Mode "Initialize non commulative".
    6: In the infocube Manage for 0IC_C03 i go in the collapse tab and enter the 2LIS_3_BX Request ID and uncheck the "NON Marker Update" to compress the request.
    7: I generate the IP & DTP for both 2LIS_3_BF & Then 2LIS_3_UM and compress both the requests in the cube by the checking the "NON MArker Update"
    8: When i run the query the data is not coming out right. Some records have negative values and some have wrong values.
    Kindly tell me what to do.
    Also, ive seen people using 2LIS_3_BF & UM only but not BX. How will this solution be implemented?

    Dear Guru,
    As off now here are the issues:
    Quantity Total Stock is matching the stock in ECC 6.0 in transaction MB5B. The issue lies with the Issue Quantity Total Stock
    & Receipt Quantity Total Stock. The values are not showing accurately but the new balance per posting date are showing accurately.
    For e.g. Cube: 0IC_C03
    Calendar Day     Issue Quantity Total Stock           Receipt Quantity Total Stock                          Quantity Total Stock
    03/31/2010                           0.000  MT                                 63.000  MT                                                63.000  MT
    04/1/2010                           78.940  MT                                 91.410  MT                                                75.470  MT
    04/2/2010                           18.000  MT                                 0.000  MT                                                57.470  MT
    MB51
    Posting Date       Issue Quantity Total Stock           Receipt Quantity Total Stock                          Quantity Total Stock
    03/31/2010                           0.000  MT                                 63.000  MT                                                63.000  MT
    04/1/2010                           68.940  MT                                 81.410  MT                                                75.470  MT
    04/2/2010                           18.000  MT                                 0.000  MT                                                57.470  MT
    As you can see the issue & reciept docs are different but the impact on quantity total stock is fine. On top of that the material documents showing in PSA are slightly more than actual showing in MB5B & MB51. Some material documents are showing as a debit entry as well as credit entry in PSA but in reality they have a debit entry or a credit one. Kindly give me a feedback.

  • POS to BC Inventory Control

    Are there any POS systems for a retail store front that can be connected to the inventory control on BC?

    Hi,
    I don't have an example to provide but as long as the POS system can speak to our available APIs then it is possible. 
    Here's a list of our current available APIs. -> http://kb.worldsecuresystems.com/635/bc_635.html

    Using the Inventory Control resposibility on OPM, and doing a

    IF we try to do the transactions above for an ITEM with no

    Doing and Ajust Immediate for the same situacion an ITEM with no

    APP-GMI-83222 No quantities exist in inventory.
    This error make a lot more sence to the user when they are
    trying to do this kind of transactions.
    Question : Is there any way we can make the other two
    transactions (Move Journal and Move immeidiate) gave to the
    users the same error message as the Adjust Immediate. All this
    because the error is showing know to them is very confusing as
    they think something is wrong with the item, or within the

  • Inventory Control Solution

    Our group has a small lab (networking, servers, other odds and ends) as well as a small equipment closet with general test gear (network analysis, spectrum analyzer, some installation gear, etc.).  Unfortunatley items frequently go missing, either someone has them on a job or took them out and didn't replace them when finished.
    I'm looking for simple methods you may have used for inventory control.  At minimum it should note the equipment status (available, checked out, unavailable/broken), the date it was checked out and planned to be returned, and the person checking it out.  Ideally it would also allow a "witness" or a controlling authority who would either authorize or witness the check-out.  Historical information on check-out/in would be nice but not a requirement at this time.  May be a future need.
    Ideal future capabilities would include ability to include photos of equipment; record various information such as serial numbers, included accessories; state of condition/repair of main item and accessories; and other information that would assist in managing and maintaining lab equipment.
    Has anyone used available (commercial or free) software, or developed a good internal spreadsheet or database for this function?  What are your recommendations or experiences?  Appreciate any feedback.
    -Ed

    I've built systems like this in the past, with any custom solution the devil is in the details, it depends on what you want to do and what you expect. As Liam has pointed out the API is your best friend here, you can develop something that pulls data from BC and puts it where you need.
    If you try to do everything at once (all those sites listed) you might find you have problems, I would start with one site first, make any changes you need there and roll out to the other platforms.
    Please drop me a PM I would be happy to assist in building.

  • INVENTORY CONTROLLED ITEM

    Hi
    Some  items are in inventory dept.(Stores)
    For that items PR can be raised by inventory dept only.
    When others raise the the PR a message has to be displayed that this item is inventory controlled item.He cannot raise the PR for that item.
    Pl reply.

    If you really want that, then you may have to code this in a user exit.
    But any inventory controlled item can be procured to cost center directly without hitting the inventory , keep this in mind.

  • Inventory report for valuation type

    Hi experts,
    Is there any SAP standard reports can show the inventory value based on the valuation type?
    we have actived the split valuation, so one material may have several valuation types. Different valuation types have different MAP and amounts.  Now we want to find the inventory value for each valuation type, for the whole inventory.
    tcode such as MB51 only can display every movement details, we want to find a report for all materials.

  • Can i use subfolders with source control for developer ?

    We'd like to use the repository as source control for our developer files.
    We planned to use the following structure in the repository:
    - Application Container
    - Folder
    - Files
    We uploaded the files in the repository.
    Now if we open the file through the ron the file will open in form builder, which is pretty good.
    The following thing I'de like to do is a checkout of the file ... ok ...i'm going to file - administration - checkout - the message occurs: no versionable object exists ! ... ? :-(.
    So I go to file - administration - source control options .. i'd like to say forms that it has to look for the file in a subfolder of the application system .. ok.
    After changing this i try again - the same message.
    If I return to source control options the container entry has been changed to the application folder.
    Are Subfolders not supported by the source control for developer ?
    Does anybody have the same effects ?

  • Follow-up transaction copy control for opportunities

    Our CRM system is currently configured to permit follow-up opportunity creation.  When follow-up transactions are created all product categories are copied to the new opportunity.  We would like to stop this.  All header and business partner data should be copied as present, however product information should not be copied.  (i.e. follow-up transactions currently work, we only want to switch off product data copying)
    I am not familiar with follow-up transaction customization, and not sure exactly where to start.  Should I be modifying the current BAdI or is there a standard customizing option to switch off copying of product categories?

    Hi Derek,
    Just try this:-
    Go to SPRO->IMG->CRM->Transactions->Basic Settings->Copying Control for Business Transactions->Define Copying Control for Transaction Types.
    Search for entry Source=oppt and target=oppt.In this entry, uncheck the check box-Copy Item Number and see if it resolves your issue or not?

  • Copy Control for Transaction Types

    Hi,
    Was wondering if someone could help on following topic. We need to specify the possibility of copy control (follow-up) for certain transaction types in CRM 6.0. I've specified the source TT (ZAPP) and the target TT (ZCON) in customizing activity : Define Copying Control for Transaction Types.
    ZAPP = Custom Appointment Activity
    ZCON = Custom Opportunity
    Now, when I want to create a follow-up for ZAPP in the WebUI (via dropdown 'More' and action 'Follow-Up'), I always get an extensive list of transaction types (about 30) rather than only the opportunity that I originally specified. Any ideas?
    Thank you,
    Sebastiaan.

    Hi Kai,
    Many thanks for your answer. Indeed, the COPY_DOCUMENT is a very good alternative as it also directs the flow for follow-up. However, I have a question in regards to using this method. I can see that there are parameters that need to be provided (like PROCESS_TYPE etc) but apart from that is it also possible to change fields in the copied document.
    e.g. Currently the description of the copied document gathers the description of the action definition, but how can you pass the description of the previous document for instance? Is this also done via the actual parameters?
    Thank you,
    Sebastiaan.
