BOM quantity changes tracking issue - please help

hi,
we use Engineering change management and change BOM with reference to a change number .
we need to have a report to know by inputtig the date and know on that date what are all the BOM changes are done using change number.
if we only add a new BOM component we are getting the details ,
when we modify the BOM component quantity we need to track the new quantity added and old quantity deleted with reference to that change number.
example : for a BOM component  A, using some change number N if we modify the quantity from 0.5 to 
               1 .
               then we should get in our report with reference to the change number  N added quantity is 1 and deleted quantity is 0.5 . when we go by the tables AENR,STAS and STPO , against the change number N we are getting only the added quantity of 1 and we are not able to get the deleted quantity 0.5
we input the  date in to table AENR and get change number AENNR for the selected date .Input this change number  to STAS  here we are able to see one record with X in the field LKENZ and one with out. from here we take STLTY,STLNR,STLKN and pass to STPO to get IDNRK,Quantity referring to the same change number .
here in this table STPO we are not getting any record with field LKENZ=X,
only added quantity record is there
deleted quantity reference record is not there
please help

hi,
AUT10 is not giving the quantity deleted or added and coponent
our major requirement is we need to have an ABAP report whose input is date and during that date using change number what changes ae doen to BOM we need to get as output
AENR table gives AENNR -change number using which on the selected date BOM changes are done
taking this AENNR from STAS table we can get the added , deleted details with respect to BOM number , etc..
using this from STPO table if i try to get
there i am getting only added components its quantity details only
about deleted  with reference to the details available in STAS , in STPO  table entries are not getting updated
today if i change BOM quantity using one change number , again the same components quantity i change after some days that addition onlly getting stored , deleted quantity(means old quantity ) is not getting stored against the change number
plz help

  • BOM quantity change (STPO-MENGE) resulting quantity less than 1

    Hi,
      Anyone have done a BOM quantity change (STPO-MENGE) where the resulting quantity is less than 1.  Please help.
      Thanks,
         Hazel

    Do you mean base quantity by saying header quantity?  I'm running variant configuration.  The base quantity is restricted to 1.  Moreover, changing the unit of measure is not an option.  Each is the official base unit of measure.
    Sample Scenario/Requirement:
    An order for a qty of 1000 requires a total 84 plates.  Each plate can yield a qty of 12.
    SAP uses the equation -->
    Current Component Qty =
                (required qty/base qty) * saved component qty
    Calculations:
    Step 1) Derive Current Component Qty
    Let required qty = order qty (VBAP-KWMENG),
              base qty = max yield per plate (given)
    Current Component Qty =
                 ceiling (VBAP-KWMENG/max yield per plate)
              = ceiling (1000/12)
              = ceiling (83.333333)
              = 84
    The Current Component Qty (84) is the qty used production orders and is equal to the Requirements Qty of the component (RESBD-MENGE)
    Step 2) Derive save component qty.  In Variant Configuration, save component qty is equal to STPO-MENGE.  Base quantity of 1 is assigned to the KMAT (configurable material).
    Since Current Component Qty =
          (required qty/base qty) * saved component qty
    by substitution -->
        84 = (1000/1) * saved component qty
    saved component qty = (84/1000)
    saved component qty = .084
    Issue/Problem:
    I have the above calculations correct in Variant Configuration.  To run a check, I do a production order simulation (CO01S) for a Total order qty of 1000 with today's Finish date.  When I click for components overview, it gives me a Requirements qty of the component of 83 and NOT 84.
    I'm not sure how SAP does the calculation in the background, but I was thinking; maybe, by increasing the number of decimals from 3 (.083) to 6 (.083333) would give me the 84 that I needed.

    Are you streaming or syncing you music? Sounds like you're streaming music directly from iTunes.
    There can be many different issues. First, try power-cycling you wireless router (leave router disconnected for about 1 or 2 minutes) to refresh the wireless communication betweek both devices.
    Make sure all software updates have been installed, for Apple TV and iTunes.

  • Mid 2010 15" MBP i5 A1286 POWER ISSUE-PLEASE HELP-

    The MBP works fine when mains connected but the only issue is every time I take the charger out it shuts down on me!!! So I have checked with a multitester & looks good the only thing i find hard to check for power is the battery itself as its hard to get a good connection, also I took to local Apple store & they checked with a new battery but said its still same issue so the guy disconnected nearly all the connecters off to check if they causing issue & he said now the battery is charging.
    So they still have the laptop to do further tests etc, but I’m not sure what could be the problem hear as maybe there is some component which is bad so the battery’s not charging or what else could be the issue please help & advice as I’m really confused as if it was something to do with the logic board then surely it would not even charge even after checking with the multitester or like Apple genius done by disconnecting other components...
    ANY HELP OR ADVICE WOULD BE HELPFULL,
    THANKS GUYS

    THANKS FOR THE HELP GUYS!!! BEEN AROUND 5 DAYS & NOT ONE PERON HAS HELPED...

    If you have a rescue email address set up on your account then you can try going to https://appleid.apple.com/ and click 'Manage your Apple ID' on the right-hand side of that page and log into your account. Then click on 'Password and Security' on the left-hand side of that page and on the right-hand side you might see an option to send security question reset info to your rescue email address.
    If you don't have a rescue email address set up then go to Express Lane  and select 'iTunes' from the list of 'products' in the middle of the screen.
    Then select 'iTunes Store', and on the next screen select 'Account Management'
    Next choose 'iTunes Store Account Questions' or 'iTunes Store account security' (it appears to vary by country) and fill in that you'd like your security questions/answers reset.

  • Trackpad Issue - Please Help!

    Hi there,
    Hope you can help me out here.
    I've recently purchased a 15" i7 Macbook pro. The machine is but 3 weeks old &, of course, very well looked after.
    A few days ago, the built-in trackpad started behaving eratically. Cursor moving by itself, not responding to touch, clicking and opening things involuntarily. Not good at all. Many users seem to have had this exact same issue.
    These problems seemed to miraculously stop after a few re-boots and possibly a software update? I really couldn't tell you what resolved the problem.
    Unfortunately I now have a totally different problem.
    There is a thin, possibly 8 to 10mm horizontal strip across the centre of the trackpad that no longer responds to touch. If I move my finger from the botom of the trackpad upwards (or vice versa), the cursor will stop momentarily as it passes over the horizontal strip. The buttons are fine and the rest of the trackpad is fine. For the moment, I've increased the cursor acceleration so that I can at least navigate round the screen with a smaller area of the trackpad. USB magic mouse seems to work fine.
    If anyone else has experienced this &/or found a solution for this issue, please help me out here. I have rifled through endless threads about MBP trackpad issues with little success & do not live close to an apple store/genius bar.
    This is a 3 week old machine that cost me a small fortune. To be getting software/hardware issues so early on in it's lifespan is really rather worrying for the future.
    Appreciate your help here.
    J

    I'm not sure what caused this, but I extended my lunch break and drove the machine down to the Westfield apple store. I didn't have an appointment with the Genius Bar but I managed to persuade one of the staff to speak to a technician in the workshop. She came back into the store and told me that they had replacement trackpads and that , considering the machine was only 3 weeks old, the technicians kindly sandwiched the repair into their timetable at zero cost. 2 Hours later, I now have a perfectly functioning trackpad/machine.
    I can't thank them enough.
    My only gripe is that I couldn't speak to a technician to find out what the problem was, how they resolved it or what causes these issues for future reference. Understanding why these problems occur often helps to build your own framework of understanding. Most of the threads i've read about trackpad issues are largely unresolved with people only speculating the problem/solution.
    The initial issue I had with the trackpad's erratic behaviour seemed to be a well known problem that many are associating with a trackpad firmware update. Unless by pure coincidence I had an immediate & major hardware fault after it, which is unlikely, my personal guess is that the two issues were related.

    Hi Venu,
    We can't add authorisation objects on Individual servers.We need to add authorisations on BWD ie Dev system and transport to BWI QUA system.This is the Process we need to follow as per our rule set.
    So,As the problem mentioned above if i add some auth. objects on BWD DEV system and transport it to BWI QUA system,it is getting transported Successfully to BWI,but the auth.objects what i have added on BW DEV system is not found on BW QUA system.
    What could be the problem for that,Is that the problem with transports like TP error or is it related with some tables of auth.objects...................
    Could u please analyse the problem and tell me the solution for this..........

    Headerrenderer issue -Please help
    hi
    I have a datagrid and I am  doing a custom sorting on the grid(by getting data from DB).
    I achieve this by capturing the headerrelease event of datagrid .In thee venthandler I will query from DB and do event.preventdefault to prevent standard grid sorting.
    Now I need to display my own custom ascending/descending arrows in the header.i have created an header renderer for this,
    In the headerrenderer I am lsitening to the headerrelease event of datagrid and in the eventlistener, as per the sortfield, i am trying to make the sort arrow visible/invisible.
    But somehow making the sort arrows visible/invisible is not working.The initial arrow works fine.it is shown the correct column(Name) as done in the init() method.
    The eventhandler is invoked on clicking the column headers and all the alerts are shown.
    Please see the headerrenderer code below and help me.(code is not complete only the relevant part is included)

    And what happened when you tried? And please don't say it didn't work, we know that. Describe what happens when you "try" to change the password. Are the settings greyed out and therefore, you can't change anything? Can you send emails? You said you can't "get" emails so i interpret that to mean that you can't receive them.
    Did you try quitting the settings app, reboot theniPad and then "try" again to see if that will allow you to change the setting?
    Tap the home button once. Then tap the home button twice and the recents tray will appear at the bottom of the screen. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the settings icon. Tap the home button twice,
    Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
    You don't have Restrictions set that would prevent you from changing the password in Settings>General>Restrictions>Allow Chamges>Accounts.

  • !!!Very Urgent-Production Issue -Please help

    Hello IDMers,
    We are facing an issue in production, we updated the AD Process form yesterday. Two fields- Employee Type and Employee ID field in AD User Process form got refreshed for all existing users. Those two fields are empty now for all users.
    But these fields have appropriate value in the Xellerate User Table for all users. Now I need to some how populate the Employee Type and Employee ID field for all employees from User Table to AD Process form.
    for example: Consider an Employee called Peter- His emp type is Full Time and Emp ID is 100; which i have it in OIM User Table, but this user is provisioned with AD and now i will have to update his AD Process form so that these two fields are populated. I need to do this for all users in OIM. I guess the prepop adapter triggers only when the form is created for the first time. Please suggest me some ideas.
    Is there a easy way to do this task?
    What my thinking is, I need to have a scheduled task that basically loops through all users and updates their employee type and id field in AD User Form from Xellerate User Table.
    Please help me with this as it is highly important.
    Thanks again every one for your support all the while.
    Regards,
    ~VSN

    hey,
    i was doing lots of migration from one OIM box to another during our last release. I guess something would have gone wrong while doing an import/export from one OIM system to another.
    What I learned was while doing an import the vulnerable object is AD USER (or any resource of OIM) Object (both Process form and process definition), because those are the two objects which you need to import fully no matter how big a change you have done.
    So when you do an import watch out for USER DEFINED FIELDS in the process form because for me the two fields which disappeared were user defined/custom created by me. So make sure you export the latest version;even if you didnt make any changes to them better create a new version copy of the form and then export it.
    Hope that helps.

  • No voice on tracks. Please help

    Hello community.
    I have the strangest problem when I'm playing music.
    I have an iphone 2g 16 Gb, and since I update (long time ago) to firmware 3.0, all the music I play has the same error: NO VOICE ON TRACKS.
    It sounds like a Karaoke.
    When I play through speaker it sounds normal, so the issue is related to the audio jack. (I've tried different kinds of headphones and still no luck).
    I've found in this forum that other people has the same problem. Is it a hardware problem?
    Does anyone solved it?
    PLEASE HELP!

    It could be a hardware problem, but more likely is caused by the headset jack not being fully inserted. Make sure you insert it until you feel and hear a click, especially if using a case.

  • MBP running at a snail's pace, and a myriad of other interrelated issues, please help :'-(

    Hello, my MBP is running very slowly, MS Office for Mac constantly freezing, Safari constantly freezing, various little issues are arising with many different functions/programs when I try to use them; i.e., the enter key will just stop working in Excel or my Adobe Acrobat will shut itself down out of nowhere, Finder freezes and/or won't relaunch; these are just a few examples, but the overall theme is that I am experiencing problems in usability and functionality with my MBP across the board. There is no rhyme or reason to any of it, and all programs and apps seem to be affected. I first began noticing the problems upon installation of the Yosemite upgrade so initially thought that was the issue, but I have since found that malware items have added themselves to my Safari extensions. I found instructions to remove them entirely, but could not find them anywhere on my computer other than the Safari extensions when I followed the steps provided. I tried clicking "uninstall", but had no luck, which is not surprising since I am pretty sure the "uninstall" option listed with the extension is just part of the malware. I have "disabled" the extensions, but that didn't do anything. I'm sure that they have implanted themselves elsewhere and are lurking in the shadows of my operating system and wreaking havoc throughout my computer.
    The whole situation is making it extremely difficult to get anything done, and if I don't fix it soon it is going to be the major contributing factor to my complete mental collapse.
    PLEASE HELP!!!
    I tried to find suggestions in other areas of the Apple Support Community, and found the EtreCheck tool in one of the discussion threads. I ran the report on my system, and it looks like my MPB is riddled with problems. I don't even know where to begin in order to correct them. I am not sure if the malware has just taken over and is behind all of these, or if I am dealing with several different sources of trouble.
    Any help with this would be much appreciated, the EtreCheck report is as follows:
    Problem description:
    MBP usability decreased significantly after installing Yosemite. Computer constantly freezing and completing any task in any program/using any function of MBP takes 5-10x as long as it used to.

    The minimum requirement is 2GB, but most people think 4GB is the bare minimum.
    I primarily buy from Crucial, Other World Computing, or MemoryTen. As long as they have a "configurator" where you pick you exact Mac from a list and it lists all the compatible memory for that Mac, AND it has a lifetime warranty on the RAM, it should be ok.  Macs are very picky about the RAM because they use it to its full capacity. If there are any faults in the modules, it will crash.
    There are suggestions for sites in other parts of the world on the EveryMac website. Look down in the Section for RAM where you'll find links to their sponsors (OWC is the US-based one).
    In Apple's world, there is a difference between and "Upgrade" and an "Update." Updates should generally be installed as they patch vulnerabilities and fix bugs.
    Upgrades on the other hand are an entirely new Operating System (OS). A change in the OS can cause many problems with your installed software as it may not be compatible with the changes. It may rely on programming interfaces that have been removed. They should know that they will be removed as Apple publishes those facts many years prior to removing the features.
    An Upgrade takes you to a major, new version of software whereas and Update just makes changes to the same major version of the software.
    Yosemite was an Upgrade, not an Update.
