Problem with MRP running

Hello Gurus,
i have a problem with my product. lets take an example. my semifinished product abc is made up of a, b and c.
i have made them(abc, a, b and c) to use MRP type VB. i made palnning file entry and BOM and then i run the MRP.
I run single item multilevel MRP for semi-finished product abc, it showed me result in MRP running only for abc but not for a, b and c.
can u please tell me where i am making any mistake.
regards

Hi Maggi,
If you have used mrp run for single item,single level  planning (ie) md03, it will plan only for that particular material & will not plan for the dependent material in the BOM.
If you run with t.code md02, MRP run for single item,multi level, all the dependent requirements will be planned.
Also VB is for reorder point planning. ie if you maint reorder level as 100 for a,b & c materials & if the stock goes below 100, say  50 Nos. for all the three material. Then procurement proposal(Pur req) will be created for 50 nos for all the material(a,b,c).
If you use MRP type PD, there is no question of reorder level, during mrp run system check the stock of the dependent requirements. If there is a shortage procurement proposal are created.

  • Problem With MRP

    Hi Friends,
    I am facing a problem with MRP. In my Implementation, my Client is a Automobile Gasket Manufacturer.
    One major product line is Gaskets which is high volume and low price
    We will use Make to stock  with streategy 40.
    Now the queries are as follows-
    1)       What should be the frequency of MRP Run for the plant (weekly , monthly of daily)
    2)       If  after one MRP Run- some Planned Orders and some Purchase Req are converted to Production Orders and Purchase Orders. My Prod Orders- 100 Pieces and PO is 1000 Kgs.
    Now subsequently , due to change in schedule,(PIR is maintained by Sales Department and it changes  often) lets say, my PIR is Changed from 100 to 10 Pieces ,
    How can a PPC  person come to know of this and inform the Buyer to foreclose the PO or amend the PO and as well change the Prod order also.
    Thanks in Advance
    Waiting for your Reply,
    Praveen

    Hi Praveen
    1) What should be the frequency of MRP Run for the plant (weekly , monthly of daily) : Daily Basis as your demand changes frequently.
    2) PPC will understand from MD04 screen where all the result of MRP as Stock Requirement List available.U cant change Production Order while running MRP as your demand changes from 100 to 10 pecies because Prodction Orders are firmed recipept.In that case you can change quantiy , do the availablity check and scheduled again  or set TECO so that it will not show up in the MD04 screen also.
    Any changes to demand and subsequent effect can be viewed through the exception messeges column in MD04/MD05
    Hope this will help you to figure it out.
    Regards

    Problem with battery running down more quickly after I downloaded OS6 to 3GS iPhone.

    I guess I should have asked for the "definitive" fix. I read several "fixes" but it seems no one knows if Apple has a definitive fix. Kind of like going into an Apple store and getting three different answers from three different reps. At least they are not rude and no, I don't have a problem searching the forum.

  • Problem in MRP RUN

    Hi,
       We are maintaining one field in suppose MRP field in MRP1view as "X".
    In  Enhancement, we develop logic like that if in material master MRP field value equal to "X", then while creating reservation,system automatically create a PR along with reservation.
    Now My Problem is -
    I created a material with MRP field as "X", MRP type as ND.
    i created a resrevation for this material,system will generate PR no. 10000002.
    Now i am changing MRP field as Blank, & MRP type as PD.
    if now i am running MRP,system will generate again a new PR.now i have two PR for the same reservation.
    i also tried in t-code MD03, planning parameter as 3 (delete & re-generate).
    so now i have two PR against a reservation,if i am checking in MD04.
    so how can we control this situation,so that only one PR can create against one reservation.
    OR can we exclude that reservation / storage location for MRP,then my problem will solve.
    Thanks
    Pavan

    When you make enhancements you are taking responsibility that all scenarios are covered, and should not expect a solution from standard SAP.
    Change the nhancement in such a way, that when you try to change from X to blank, system will issue a message saying that Preqs exist, and thus will not let change before those are deleted.
    This will prevent the double coverage issue.

  • Problem with threads running javaw

    Hi,
    Having a problem with multi thread programming using client server sockets. The program works find when starting the the application in a console using java muti.java , but when using javaw multi.java the program doesnt die and have to kill it in the task manager. The program doesnt display any of my gui error messages either when the server disconnect the client. all works find in a console. any advice on this as I havent been able to understand why this is happening? any comment would be appreciated.

    troy,
    Try and post a minimum code sample of your app which
    does not work.
    When using javaw, make sure you redirect the standard
    error and standard output streams to file.
    Graeme.Hi Graeme,
    I dont understand what you mean by redirection to file? some of my code below.
    The code works fine under a console, code is supposed to exit when the client (the other server )disconnects. the problem is that but the clientworker side of the code still works. which under console it doesnt.

  • A few problems with Leopard running on my White iMac...

    I have only found 2 problems so far with Leopard running on my iMac. First off, the most annoying one:
    Sometimes, especially when switching users, the screen turns to the "gray screen of death." You know, the one with the request to restart your computer in like 4 languages and a huge picture of a power button... anyway, it is getting quite annoying and I wish I could make it stop. It has also happened when I have been dealing with moving large amounts of data, "large pictures, movies, etc.)
    And now, the second problem. I was just looking up the memory left on my hard drive when I noticed something I hadn't before. my 160gb hard drive had 50gb left. not too strange there. but when I checked through all the things (apps, users, system, library, developer, etc.) in it (I simply did apple-i and checked the gb each of them took up) and after a quick add-up on my calculator widget, all the things in the hard drive added up to 50gb. so I have 50gb free, 50gb used and a 160gb hard drive. How does that work? Do I need to do something to get that extra 60gb back or is it just gone???

  • Problem during MRP RUN.

    HELLO, FRIENDS,
    if i select mixed MRP in the material master with indicator 2 i.e.gross reqirement
    for MRP run ,but after taking MRP run through md01 .its not exploding dependent requirement of its component.Is there any setting for this?
    lpease give solution
    regards,]mangesh

    Hi,
    Check with t.code CS11 & check the result whether BOM is exploding or not.
    Then check in t.code OS23, whether mrp exlosion is activated or not.
    Check the BOM usage used while creating the BOM.

  • Dates problem in MRP Run

    Hello
    i m running mrp using zpp_md50 is the zprogramme for running the mrp for all the line items in one sales order,  after running the MRP, whatever the pur. req. generated we will convert it to PO, but client need one release statergy here so that  they can take the assurance from the suppling plant that whatever the date mrp run showing is that plant is really able to supply the goods on that date or not.
    1) if suppling plant is not able to send the goods on the requested date in that case receving plant should be able do the amendment (change) in dates in their panning so that they can give the new delivery date to the customer?how to achive this?
    2) They also want when we run the MRP, system has to consider the unrestricted stock present for the sales order line item,but without giving the sales order ref. using 412e to sales order.cause their r huge no of line item in sales order.
    3) my client is not able to achive the customer date so it is very imp to do the amendment in mrp dates cause the dependacy is on the supplying plant & the suppling plant can produse only taking  material grades of the same item at a time & it is not possible for suppling plant to produce as per the delivery date of the order.so  the date in master ie. in house production date maintain is not really going to be follow, as the plant is critical, plz suggest some solutions for this also?
    Regards
    Nishj.

    Nishj,
    Wow.  Substantial requirements.  Let me see how many of these I can help you with.
    i m running mrp using zpp_md50
    Please understand that that program is custom to your system.   It will be hard for us to comment on it's workings.
    they can take the assurance from the suppling plant
    It seems that you are selling the product from one plant but manufacturing in another
    if suppling plant is not able to send the goods on the requested date in that case receving plant should be able do the amendment (change) in dates in their panning so that they can give the new delivery date to the customer?
    This is standard in SAP.  Basically, the suppying plant will create a supply element (production order, process order, perhaps in conjunction with a Stock Transport order) to move the parts to the selling plant.  Once this element is in place, someone from Sales or another appropriate functional group will re-ATP the sales order.  The sales order will then re-confirm against the new, more accurate dates.
    They also want when we run the MRP, system has to consider the unrestricted stock present for the sales order line item,but without giving the sales order ref.
    This can be achieved easily, by not using a MTO strategy.  If you use strategy 40, Sales orders ATP, and all MRP calculations, will make use of all unrestricted stock.  If there then is NO sales order stock, then this means that ALL stock is included.  Just avoid any MTO strategies throughout your BOM.
    There is no standard SAP functionality that will include Sales order stock and unrestricted stock simultaneously for the same part for the same requirement.
    my client is not able to achive the customer date so it is very imp to do the amendment in mrp dates....
    I am not sure what you are asking for here.  You have stated the solution:  The supplying plant does their research, and they then create a supply element with the realistic dates.  The Sales order ATP check will then re-confirm to those dates.  MRP will also run using those modified dates.

  • Problem with Macro Running When Closing a Document

    Hi Folks;
    I'm trying to develop a Visio macro that runs when I close a document, but I've run into a snag...
    The problem is that the code below only works when I press the 'X' in the corner of the document to close it.  If I try to close it using
    File -> Close, I get the error "Run Time Error -2032464741 (86db0c9b) An exception occurred", and the debugger highlights the first 'Application' line.
    I need the code to work regardless of the close operation, and I'm not sure how to make that happen (since I assumed it should've work the same regardless).
    Private Function Document_QueryCancelDocumentClose(ByVal doc As IVDocument) As Boolean
    Document_QueryCancelDocumentClose = True
    If MsgBox("If you made changes, did you UPDATE the Diagram History? (Select Yes if no changes were made)", vbYesNo + vbCritical + vbDefaultButton2, "Warning - DIAGRAM HISTORY UPDATED?") = vbYes Then
    Application.ActiveDocument.Pages.ItemU("Diagram").Layers.Item("Warning").CellsC(4) = 1
    Document_QueryCancelDocumentClose = False
    Else
    Document_QueryCancelDocumentClose = True
    End If
    End Function
    Any help would be appreciated.
    Zang

    I'm betting your typical "try this" response is not what anyone wants.  But since you've chimed in... my problems with the Visio event model are PLENTY.  Print and save events that cannot be cancelled, document close that doesn't fire on application
    close, and Application.BeforeDocumentSaveAs that occurs WAY AFTER the document has been saved are just a few.  (Did Microsoft even test these events??)  The official Microsoft response to ALL of this was, in a word, "repurpose" it. Essentially they
    advocate completely rewriting the actual Save and Print portions of the interface and corresponding logic in Visio by intercepting keystrokes and redirecting ribbon extensibility idMso ="FileSave" and idMso ="FileSaveAs" commands to your own methods. 
    To quote paid support:
    "You may repurpose Save command in Visio as suggested in my previous email, however there is a design limitation that does not allow repurposing Print backstage button.
    In order to achieve Visio Print repurpose, the workaround is to hide the print back stage altogether and plug with custom backstage ribbon xml."
    We now also repurpose idMso="FilePrintQuick", idMso="FilePrintPreview", and idMso="FileClose" customUI commands, but we still had to use the logic above to catch save before closing. 
    Valid methods that work while Visio is active will fail within Application close.  IT IS A BUG IN VISIO.  That is what this post is about.

  • Problem with DOM4j running on JRockit

    Until recently, we were using SUN Java JVM for running our applications and now we run it on JRockit. Ever since we made this change, we are experiencing this strange problem with DOM4j.
    There is a certain set of XMLs in our application, which do not have any schema (neither DTD nor XSD). We use DOM4J (v1.4) for on the fly unmarshalling of these XMLs and then use XPath to extract the data. There is method in DOM4j (Element.selectNodes()) which extracts the relevant information from the XML based on the XPath provided. The problem is, this List which this method returns, contains a 'null'. This would result in a NullPointerException later on in the program execution.
    Please note that since we did not have this problem in SUN JVM, I presume that there is some kind of incompatibility between JRockit and DOM4j. That is why I am posting this question here.
    Thanks in advance.
    Cheers,
    -Nagendra

    Hi Henrik,
    Thanks for your reply.
    We are using R26.4 version of JRockit.
    This problem occurs only on our production servers and the occurance in not consistent as well. Early on in the runtime of the server, everything is ok (including the functionality which would give this problem). But, aprroximately after 2 days of running, the server starts giving this problem. Forcing us to restart the application. Since application uptime is a critical deliverable for us, this problem has become a bottleneck for us.
    Haven't tried -Xnoopt JVM option yet.
    Thanks.

  • Problem with Fan Running

    I'm having problems with my new(ish) iMac. This problem is a bit involved so please bear with me.
    While adding a torrent to my downloading program azureus, my computer froze. It would not allow me to shut down or do anything. So I unplugged the machine and waited awhile and attempted to restart. To my horror, it would not start up. I then unplugged the power cord in the back and held the power button while plugging the cord back in and then released and pressed the power button again. My computer turned back on, hooray, BUT, now the fan is running very loudly and has not stopped. I restarted, shut down and left it alone, and now I'm very confused. Any suggestions?
    thanks

    Hi Lisa!
    You should go to this link: http://docs.info.apple.com/article.html?artnum=301733 - you've basically reset the SMU on your machine but read the article and follow carefully. You should go ahead and reset the PRAM, which is also covered in the article.

  • Any problems with lion running on core 2 duo 2007 MBPro ?

    Curious to hear if anyone has had any problems with Lion before I upgrade.
    Thanks.

    OK, so this is a shot in the dark, but maybe it's worth a try.
    Since the problem only occurs when running on battery, perhaps changing the Energy Saver settings to match the settings used for when it's plugged in will fix the problem. The default settings for how the computer operates are different for the battery and power adaptor. When you unplug the power, the computer automatically shifts to the alternate settings.
    So, try this:
    -Open System Preferences->Energy Saver
    -In the "Settings for" drop-down menu, select "Battery".
    -In the "Optimization" drop-down menu, select "Better Performance".
    -Under the Sleep tab, choose "Never" for both computer and display sleep and uncheck the box for "Put the hard disk to sleep when possible".
    -Under the Options tab, uncheck the first two boxes.

  • Problems with colors running CS4 and W7.

    Hey everyone.
    I'm having some MASSIVE problems with colors on my system.
    Windows 7 Prof 64bit
    Photoshop CS4 64bit
    6g Ram
    1T hard drive
    Nvidia GeForce 9800 GTX+
    Dell SE198WFP Monitor 
    The system itself is a Dell Inspiron 530 that I put into a Black Widow V9 gaming tower. 
    Here is an example of the issue I'm having: 
    http://findae.deviantart.com/art/Converge-101214480
    http://i38.tinypic.com/bjcymr.jpg 
    The top image is a (admittedly old and crappy, but it shows the problem) photo that I had previously edited and put in my portfolio. The tinypic below is the result of copying that photo from the portfolio, pasting it into photoshop, and then saving it into a jpg. As you can see, the transitions between colors and the contrast are a complete mess. 
    Thing is, my hard drive recently quit on me, and I had to install the operating system and such on a new drive. I remember having this problem with the system when I first had it, but it either went away on its own or I fixed it somehow before. Now I can't remember for the life of me how I got rid of the problem, and I certainly don't know what the problem is in the first place. I'm tempted to think it may not be photoshop itself, but the problem seems to be especially bad when I'm working with photos. 
    Anyone have any idea what the problem might be and how to solve it? 
    Edit: I also noticed it when viewing http://findae.deviantart.com/gallery/#/d1hni37 in firefox, whereas the other photo appeared to be ok before I copied and pasted it. It has extremely obvious lines of green and orange in the transition from light skin tone to dark skin tone. Annoyingly enough, this doesn't show up in the thumbnail within my gallery at all, only when I click on the thumbnail and see the fullsize image. Extremely frustrating.  
    Here's another good look at the problem while selecting a color in photoshop: http://i37.tinypic.com/2h6t7gh.jpg  All I did was screenshot it a few times, and it deteriorated to that point.

    Screen glitches like color blocks appearing where they shouldn't could indicate a problem with your video drivers.
    Go to the nVidia site and see if they've released any updated drivers; people often report that updated drivers are correcting current problems with Photoshop.

    Note the recent (3 weeks ago) release.
