Item cost not found for one or more items - Inventory Posting

Good Day Mentors,
My user has encountered an error during Inventory Posting and its "Item cost not found for one or more items".
The specific Message ID from SAP's System Message Log is 10001287.
I found a similar post which addresses this error here.
But unfortunately it did not help me solve my user's problem.
I already checked if the items had a defined "Item Cost" in the Item Master Data Inventory Tab, and they all have "Item Cost" defined.
I'm not sure if this will help, but below is the Inventory Audit Report of one of the items that is throwing the "Item cost not found" error.
I am not a business consultant neither am I literate in accounting, so thanks for the patience.
SAP Version: 9.0 PL5
Valuation Method: Moving Average
Thanks in advance!

Hi Augusto and Raviraj,
I've already verified in our production database the points you made:
- Is the "Manage Item cost per warehouse" selected in the Basic Initialization Screen?
YES
- Is the "Manage Inventory by Warehouse" ticked/checked in the "Inventory Data" tab of the "Item Master Data" screen?
YES
* I apologize for not have been able to give this information upfront.
Anyway, the database only has one warehouse at the moment.
I've checked the items, like the item in the screen shot above, and it does have an item cost.
Below is the screenshot of the sample item from my original post,
Thanks in advance!

Malicious or not? Message popped up: Mozilla security found (something like too much, forget exact word) activity on your computer so it will do a fast scan of system file. With OK button.

I was looking at youtube.com, which always tells me my browser is not supported and recommends I download Firefox, but that is what I was using, so I went to Firefox to check for updates. (I think I also had freecycle.org open.) Then this message popped up in a new page: Mozilla security found (something like "too much", forget exact word) activity on your computer so it will do a fast scan of system file. There was an OK button. The page address was: http://update17.stegner.ce.ms/index.php?Q7Lhl9ShbRxGJXpkM1VLSi4ZE8H4pTedoVPySgeppM3VpC+thEspcFG7qxHgn1pdsC2h5ygPGWI3t5hXqMzL9EQaZZ3J1e3CKXgCb0Qp. I did not click OK but copied the link and closed the window which closed the internet. I have never seen this before and would like to know if it is really Mozilla or possibly something malicious. Thank you.

Good catch. That almost certainly is an invitation to download malware.
There are a lot of infected web sites pushing "fake antivirus" software. If you have any doubts about whether your system might have become infected, you can supplement your regular security software with these two highly regarded scanners:

Songs that I have purchased are missing in iTunes (file not found/exclmation point), and do not show up in the iTunes Store for download.

I have a laptop that has (or had) pretty much all of my music, both burned from CDs and downloaded from iTunes. My 17 year old son on occasion syncs his iPhone and iPad with this laptop. As of the last sync (as best I can determine), many songs that I purchased in the past few years are now missing, in that they have an exclamation point to the left of the song title, and when I try to play the song, I get an error message that says "The song could not be used because the original file could not be found" or something to that effect. As it turns out, the file seems to be erased. This has happened multiple times, and I could be wrong, but I believe that there are some songs that had the exclmation point last time he synced that now don't, and vice-versa. There is not an obvious correlation or grouping as to why these songs are missing (e.g,. they were not all purchased on the same date, not all songs from one artist are missing, etc.).
Since most of these songs have been purchased through iTunes through my account, my reaction was to go to the iTunes store, log in with my account, and re-download them. Problem is, all of these songs instead ask me to purchase the song, instead of displaying a "cloud" logo. Therefore, it appears that I have to re-purchase these songs, which does not sound correct.
Questions: Does anyone know, most importantly (to get an immediate fix):
1. How can I re-download these songs and why doesn't iTunes Store recognize that I have already purchased them?
and perhaps as important (more of a long-term question):
2. Why does this happen and how can I prevent this from happening again (since it has happened multiple times)?
Thanks.

1. iTunes won't offer cloud downloads for songs that it "thinks" are in your library, even if it "knows" the files are missing. If you've exhaustively searched for the missing files and there is no prospect of repair by restoring to them to their original locations, or connecting to new ones, then delete that tracks that display both the missing exclamation mark and are of media kind Purchased/Protected AAC audio file. Don't hide from iTunes in the cloud when asked, close iTunes, then reopen. You can download from the cloud links or iTunes Store > Quicklinks > Purchased > Music > Not on this computer > All songs > Download all.
2. Why? Not sure, perhaps 3rd party tools or accidental key presses combined with previously hidden warning messages when trying to organize the library. There is a hint that using the feature to downsample media as it is synced to a device may also be involved, though I've not replicated it. Whatever the reason a backup would protect your media.

I've just found that three movies I've bought from iTunes on on my iPad are not showing up on Apple TV or anywhere other than that iPad. What's up with that and will I lose these films if I reset this iPad?

I've just found that three movies I've bought from iTunes on on my iPad are not showing up on Apple TV or anywhere other than that iPad. What's up with that and will I lose these films if I reset this iPad?

Thanks. The reason this has become an issue is that I recently bought a new Macbook Air that the iPad is not synced to. The one is was synced to was stolen. If I want to sync this iPad to the new Air, won't it be wiped before I'm able to copy these films or am I wrong about that?

My iphone wont let me play songs that I bought from iTunes. It says "The requested URL was not found on this server" How can i play my music also my music videos again?

I bought a few songs and music videos from iTunes, then all of a sudden it wouldn't play and would just skip to the next song. With the music videos it would do the same. Also, this message would show up " The Requested URL could not be found on this server" What does that exactly mean? And what do I need to do to play my music/videos again?

This previous discussion has a solution:

Itunes wont open at all, error message : quicktime was not found .... please reinstall ... i did that but no luck this only seems to have happened since the 10.4 update, im on windows 7 ..

itunes wont open at all, error message : quicktime was not found .... please reinstall ... i did that but no luck this only seems to have happened since the 10.4 update, im on windows 7 ..

Can you start QuickTime on your computer?
You'll probably have to search for the Windows Installer Cleanup Utility and use it to remove QuickTime Player and iTunes. Then download and install the iTunes again.

External Display not being found

Hey i posted this under macbook display but no one really goes in there so can you guys help??
Hi recently i borrowed a friends official apple mini-dvi to video adapter to watch a movie with my macbook. He uses the cable with his iMac. I tried plugging it in, the screen flashes blue then nothing appears on the tv. no picture nothing. i tried restarting with it plugged in, restart without, putting it to sleep plugging it in then waking it and nothing works. so i thought maybe the cable is broken. so i go to my friend and we hook it up the same way i was with his iMac and it works so we unplug his and plug it in to mine and it still does not work. HELP???

Your display may not be on the "approved" list, or was removed from it.
Apple's new MacBook lines includes a form of digital copy protection that will prevent protected media, such as DRM-infused iTunes movies, from playing back on devices that aren't compliant with the new priority protection measures.
The Intel-developed technology is called High-bandwidth Digital Content Protection (HDCP) and aims to prevent copying of digital audio and video content as it travels across a variety of display connectors, even if such copying is not in violation of fair use laws.
Among the connectors supported by the technology are the Mini DisplayPort found on Apple's latest MacBook, MacBook Pro, and MacBook Air, in addition to others such as Digital Visual Interface (DVI), High-Definition Multimedia Interface (HDMI), Gigabit Video Interface (GVIF), and Unified Display Interface (UDI).
Apple has apparently acquired a license for the technology and is now using it across its DisplayPort-enabled MacBook lines to to prevent transmission of purchased iTunes content (and some DVDs) to devices that don't include support for HDCP.

I was updating Firefox from version 6 to version 7, after updating I tried to open Firefox and the message I got is this: This application has failed to start because xul.dll was not found. How can I fix this?

I was updating Firefox to the newest version 7.0.1 from version 6.0.2 I think it was, I clicked the restart Firefox button that always comes up after updating. It started updating and then Firefox never restarted like it was supposed to after it was done updating. I then tried to open Firefox and it told me "This application has failed to start because xul.dll was not found." I did have Firefox crash on maybe about 30 minutes or so earlier which bothered me because I have been using Firefox for years and never had it crash on me before but I didn't think much of it at the time it happened because I was able to go back onto Firefox and finish what I had been working on. A while later I checked for updates and updated. The first time I tried to update it didn't work though so I had to shutdown Firefox and reopen Firefox and start the update a second time. It was after the second time that when I tried to open Firefox I got that message about failing to start because xul.dll can't be found. I filed a crash report when my Firefox crashed. This would have been around 1am-2am in the morning that Firefox first crashed and then wouldn't allow me to open it after updating. I have a DELL laptop running the Windows XP operating system but the laptop is probably at least 6 or 7 years old. The laptop will no longer charge so I always have to have it plugged into an outlet. Both my laptop hard drive and my external hard drive give me messages that I am running out of disk space on my hard drive. I bought this laptop 6 or 7 years ago second hand so it could be even older. In short it's a piece of crap and it gives me all kinds of issues but I currently can't afford a new one, but I have never had any problems with Firefox and I use Firefox more than any other aspect of my laptop so it's really really bothering me. May you please help me fix it?

Unfortunately I tried that and it didn't work. Thanks for the help though. I tried to uninstall and it said I couldn't because the file is corrupt or something, but I think I finally got it uninstalled and/or deleted or whatever, but now I try to reinstall/download it again from the beginning and I can't. No matter what I do I can not get Firefox working again. No matter how many times I try to redownload it. Any other suggestions?

Hi,
Assuming your initialization matches your discoverer login, it is pretty weird that you get no data.
I am not sure how you got the SQL but i suggest you trace the session to get the exact SQL ran by the discoverer.
You may find another condition or join that limits your data.
Also another thing that you should try is to initial the session by using all the parameters (including the security group as you have in your discoverer login):
begin
fnd_global.APPS_INITIALIZE(user_id =>, resp_id =>, resp_appl_id =>, security_group_id =>);
end

JBO:33001 bc4j.xcfg file not found in class path

Hi,
I am yet another victim of the age-old error JBO:33001 bc4j.xcfg file not found in class path, When i have my BC4JApp.jar in Tomcat Web-inf/lib directory. All the other jar files and class files in my webserver-application web-inf classes and lib directory works.
But Tomcat server is not able to read this bc4j.xcfg file. I can see in my jar file that this bc4j.xcfg exists and in the specified package directory. still the problem persists. My BC4JApp.jar is perfectly working when i use JDeveloper. but not when i use tomcat4.0 and call a JSP using BC4JApp.jar from browser (My environment is Jdeveloper3.2, Tomcat4.0+IIS in middle tier and oracle 8i as DB, everything on windows2k)
I have gone through almost all the threads possible that relates to this error in this form. None of them have a answer except to say "put the file in classpath". and last reply is "will fix in jDeveloper 9i. So what happens to us who are working in Jdeveloper 3.2?
1. I have this file in my jar file.
2. I also tried creating a seperate directory manually, with the same name as my package under web-inf/classes, web-inf/lib , just under web-inf directory and atlast under approot directory also. I tried having my package directory containing bc4j.xcfg in these folders one at a time and also tried having this directory in all these folders at the same time.
Still no solution.
Itz frustrating that neither proper documentation nor a right url page nor i am aware of available addressing this. page links given in above threads only gives me the wonderful page of ie's "Page cannot be displayed".
Is there a answer to this error and my problem. If this doesn't work, then i have to all the way develop from scratch creating my jsp using JDBC calls and Stored packages etc.
I don't want to give up on this Jdeveloper at this final moment because if this bc4j.xcfg file is found, my application will work perfectly. on these final moments, if this doesn't work, i am frightened to imagine to develop my application in standard way. Atlast, if thatz the option left,we have to do that bcos our production date is close by.
Please can some one in this forum or Jdeveloper help me to solve this problem. I am desperate and very urgent.
Waiting for a reply from Jdev team very much...
( I just posted in the other thread which is pretty old, dated backto May 2001, which was relevant to this error. Just to make sure it is noticed, I am posting it seperately too)
Thanks

Hi All,
For those who are following this thread, I got a solution for this error with the help of Jdev Team.
This solution may work, if you have deployed your application in Tomcat4.0.1. This is the environment in which I work and tested.
As you may be aware, Tomcat ignores value in CLASSPATH variable.
To see any files that are existing or newly deployed, it has it own way of detecting it.
Addition information on Tomcat working, you can follow this link,
http://jakarta.apache.org/tomcat/tomcat-4.0-doc/index.html
Coming to point, Tomcat has got five classloaders and each classloader invoked, looks in their related directories for files in following order.
1. /WEB-INF/classes of your web-application
2. /WEB-INF/lib/*.jar of your web application
3. BootStrap classes of your JVM (Tomcat's $JAVA_HOME/jre/lib/ext)
4. System class loader classes($CATALINA_HOME/bin/bootstrap.jar,CATALINA_HOME/lib/tools.jar)
5. $CATALINA_HOME/common/classes
6. $CATALINA_HOME/common/lib/*.jar
7. $CATALINA_HOME//classes
8. $CATALINA_HOME/lib/*.jar
So All your individual application related files should be deployed in your application's WEB-INF/classes or WEB-INF/lib directory accordingly.
If your application files are unpacked, they should be deployed or copied under WEB-INF/classes directory
if the files are within a jar, they should be under WEB-INF/lib directory.
If your Jar-files contains bc4j components, then those jar files should be deployed under WEB-INF/lib directory. Also,do the next step to copy all relavant BC4J runtime libraries under lib directory.
IMPORTANT: Please remember to copy and paste all the required BC4j runtime libraries in the Same WEB-INF/lib directory along with your application jar files. This is the real reason which can solve this JBO:33001 to disappear. It worked for me.
To configure your directory for tag-lib uri's, use web.xml to set the taglib-uri attribute.
Put your web.xml and DataTags.tld in the WEB-INF directory.
Your simple web.xml may look like as follows.
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
     <taglib>
          <taglib-uri>
               /webapp/DataTags.tld
          </taglib-uri>
          <taglib-location>
               /WEB-INF/DataTags.tld
          </taglib-location>
     </taglib>
</web-app>
You may then modify this web.xml to suit further requirements of your application.
Remember to stop and restart the Tomcat Server (service) by using shutdown and startup scripts after updating any jar files/class files/ JSP or source files deployed in Tomcat.
Sometimes, only this helps even though your context's reloadable attribute is set to true in Tomcat Server's server.xml file.
Hope this above information helps you to solve this error in Tomcat environment. My Sincere thanks once again to Juan and Jdev team for their help and efforts to solve this problem.
Thanks
Hari

File not found error

I get the following error, but don't know why it can't find the file. Is there anything in this script that would call "\" instead of "/"? Is there any line of code that will switch a wayward "\" back?

Error: "file not found" when try to display image on report

Dear All
I have a problem when running my report.
My Table emp_info Stores all data about employees in addition to the employee image path.
I made a report that display employee information including its photo.
I run my report passing the parameter p_emp_id to display the desired emploree information.
I made a field on the report to display the employee image
and i set its property READ FROM FILE = YES and FILE FORMAT=IMAGE
But the following error occurs
"File '\\iai3\iaigc\ALL\emp_images\51.JPG' not found. "
I'm sure that the path is correct
But i do not know why the report stops and can not read the image path.
My platform is:
Oracle application server installed on linux
and oracle report builder installed on widows for development

Dear aweiden
thanks for replaying
I belive you are right . I think the problem is in the path.
But there is something that i did not mentioned to you. I work on two different servers.
1- "iai2" : Linux server which contains oracle application server.
2- "iai3" Windows 2003 server which contained oracle database 10g and the folder "aigc\ALL\emp_images" which contains Employees images
I think that the problem is that Linux server can not understand the path "\\iai3\iaigc\ALL\emp_images\51.JPG".
Do you have any idea how the path should be changed so that Linux can recognizes it.
Thanks in advance
