Problem with show data of system R/3

Hi all,
I have a proyect with web dynpro, and i like get data of system R/3. I get this data with the connection JCO.
I have make all steps for crate the web dynpro and i see the application when deploy and run, but data of system R/3 i not see.
I have created a connection with Jco in Web dynpro Administrator and the test is good.
How can i make for get the data in the table of webdynpro?
Thanks in advance.
Vicente Zaragoza.

Hi,
You mentioned that there is no problem with JCO connection, if it is so then you should check the mapping of attributes to to UI elements (Usually you will map Model(BAPI) to coustom controller and coustom controllet to View Check are you mapping attributes, then In view you should map UI elements to attriburtes(Value attributr/value node depending on the context).
And check in coustom controller's source code you are excuting a function module (Method to call function module /BAPI) and in WDINit method creat function module object similar to below mentioned code
Bapi_Persdata_Getdetailedlist_Input bapiInput = new Bapi_Persdata_Getdetailedlist_Input();
wdContext.nodeBapi_Persdata_Getdetailedlist_Input().bind(bapiInput);
in view invoke this method

Problem with showing battery and system information in openbox

I wanted to install docks( in open box wm ) which give me battery life information and some thing like that but when I run them terminal give me this error :
CPU frequency scaling NOT available
No power management subsystem detected
No power management support...
what should I do
Last edited by sarsanaee (2013-08-08 15:14:42)

well.. dockapps are veery old fashioned way to do that. If you look at wmpower app on that site you see it hasn't been updated for nearly five years, so i'm not surprised if it's not working on a modern system.
many people use conky to display power status on openbox, so you might want to look into that..
you can add power applet to various panels (xfce-panel, gnome-panel etc.) and use the panel with your openbox session
you could also code/google for openbox pipe menu script that does what you need
if none of those options work for you i found this git repository that seems to be still maintaied that holds wmpower and some other dockapps: http://repo.or.cz/w/dockapps.git
unfortunately couldn't find PKGBUILD for that on AUR...

What is wrong with my Data Guard system?

What is wrong with my Data Guard system(10g10.2.0 on OEL5.0)? What method should I take to diagnose it and repair it?

Problem with the date conversion

Hi Friends,
i am facing the problem with the date conversion, Actuall my requirement is to pass the date to the screen based on the user setting roles(SU01).
I have fetched the user setting date format by using the funciton module SUSR_GET_USER_DEFAULTS, The function module picks the exact user date setting (Like as MM/DD/YYYY, MM.DD.YYYY, DD.MM.YY).
After that i have implemented the FORMAT_DATE_4_OUTPUT funciton module for converting of the user role setting date format into system date format.
for the english language case the funciton module FORMAT_DATE_4_OUTPUT works fine but the funciton module not supported for other languages
Can you please provide the Function Moudle for user setting date conversion.
The funciton module is most important for us,
Thanks

Problem with a data set: DIAdem crashes

Hi,
I've got a problem with a data set. When I want to zoom in DIAdem-View, DIAdem crashes with the following message (translated from German ;-):
error type: FLOAT INEXACT RESULT or FLOAT INVALID OPERATION or FLOAT STACK CHECK
error address: 00016CB8
module name: gfsview.DLL
I've got some similar data set not showing such problems. Further on I scanned the data a bit, but in the 59000 points I didn't see anything special. I did try to delete "NOVALUE"s as well, but after that there still exist "NOVALUE"s.
Does anyone have an idea what to look for?
Thanks,
Carsten

Carsten,
Could you please upload you Citadel database to the following FTP site:
ftp.ni.com/incoming
If you want to compress (ZIP) and/or put a password on the data, that's fine. Please send me a private email at [email protected] (with the file name and password if you put one on the file) once you have uploaded the file and I will check it out.

Problem with showing mp3 album art in list view.

Hello.
I have litle problem with showing mp3 album artwork in list view.
In SNOW LEOPARD all work fine, and all mp3 files have album art's preview in list mode in finder.
But in LION i have only default preview mp3 icon.
Option "Show icon preview" is already on!

I have the fix!!!!
I have had the same issue ever since Lion. Its been very painful not having album art preview in finder or the play button when rollover the file for so many versions of OSX. Today I worked hard in trying to solve the problem since Applecare support hasn't helped much, all they did was tell me to bring the computer in. The other main reason I got so motivated to try and fix this is because the DJ app for Mac only reads album art from the finder even if iTunes can display the album art. The other reason that got me curious is that my friends macbook pro album art worked fine, so I cross checked with his computer until I figured out a few things that helped and ultimately fixed the issue. FINALLY!
My set up:
- I have my full iTunes library folder on my external as I have over 700GB of music.
- It includes all my database files in there, which is very important as I have many playlist settings from over 7 years of iTunes activity.
SOLUTION:
1. With every new computer I have purchased, I use to just pressed option on Mac and press iTunes to locate my folder (which I have said is located on my external drive).
2. I tried today to press option again BUT locate and selected the default library in the user/music folder of my internal drive (standard setting from Apple).
3. Miraculously, all the album art appeared in both my external drive library and also today's downloaded songs on my Macbook pro. Ofcourse with the new default location I don't have any songs or data.
4. So I tried to find a way to keep this library data on my internal drive since it can help the finder display all my files properly, yes even have the play on rollover button but as well link it back to my external drive with all my 700GB songs.
5. I then went into iTunes Preferences/Advance tab and in iTunes Media folder locationredirected the location to my external drive iTunes/ iTunes Media folder. If it asks to collate data, press NO.
6. Then I quit iTunes.
7. Next I copied the 4 files to my desktop from my external drive as I want to keep the data I have made with all my playlists etc. The four files are iTunes Library Extras.itdb ,iTunes Library Genius.itdb , iTunes Library.itl , iTunes Library.xml
8. I then went to my internal drive User/Music/Itunes/ and dragged these 4 files I copied from my external drive into here and making sure to REPLACE the four existing files already there.
9. Next open iTunes and you will find all your presettings appear with all your music linked to your external. What this does is keep the important library files on your internal drive (that somehow makes your finder files album art appear), BUT to read also all the music mp3 files located in the external drive (action from step 5)
Presto!! All your music files whether on internal drive or external all the album art has appeared.
Hope this helps!! Let me know if there are any other questions.

Is anyone else having problems with Apertures Date fields?

After experiencing a sysems failure I began restoring my images from backups. I have had no end of problems with Image dates. I have come to the determination that Aperture is NOT using either the "Create Date" or "DateTimeOriginal" as the image "Date" or "Date Created" data if other fields have other dates.
Here is a clip from my image metadata using exiftool:
File Modification Date/Time     : 2012:09:23 19:53:15-04:00
File Access Date/Time           : 2013:01:16 11:34:38-05:00
File Inode Change Date/Time     : 2013:01:16 11:31:32-05:00
Create Date                          : 2006:02:20 11:51:12.10
Date/Time Original              : 2006:02:20 16:51:12.10
Modify Date                          : 2006:02:20 11:51:12.10
And here is what Aperture utilized on import
Date:                               9/23/12 7:53:15 PM EDT
Date Created                         9/23/2012 7:53:15 PM
So Aperture utlized the File Modification Date/Time as the Create Date despite that the fact that the Create Date field is present and is properly formatted in the original image.
According to the Aperture mapping table, this shouldn't be happening.
Now, before someone recommends that I use Aperture's Date Adjust utility - I'm talking about slightly over 30,000 images. Editing images one at a time, or in blocks when you don't know what field Aperture is using as the Create Date would require individual inspection of each image followed by manual adjustment of each image. That approach isn't acceptable.

Hmm ok, let me restate the issue then, I thought I was clear. I could have pointed out in my original post however, that only the EXIF and IPTC date fields were displayed from the metadata dump.
The data set presented in my first post is the EXIF dataset from the file which clearly shows the image was captured by digital camera at
Create Date                          : 2006:02:20 11:51:12.10
Date/Time Original              : 2006:02:20 16:51:12.10
(The delta of 5 hours is the result of Zulu versus local time offset)
But, when I ingested it into Aperture, the import routine utilized the IPTC field
File Modification Date/Time     : 2012:09:23 19:53:15-04:00
which is updated by the OS whenever you move the file around outside of Aperture. (a number of image data fields are updated by the OS - filename for example is another.). This resulted in the image date fields being stamped in Aperture as:
Date:                               9/23/12 7:53:15 PM EDT
Date Created                         9/23/2012 7:53:15 PM
Which obviously came form the File Modification Date/Time field and not (either) the Create Date or Date/Time Original fields.

Problem with Java Dates and UPDATE for SQL2000

I am having problems with the date formats for Java. I am trying to put the current date time into a SQL table, here it the code I am using:
var Today = new Date()
var conn = Server.CreateObject( "ADODB.Connection" )
conn.Open( "Provider=SQLOLEDB;Server=(local);Database=BillTracking;UID=sa;PWD=;")
var sql = "UPDATE BillAssignments SET DatePosted = " + Today + " WHERE AssignmentID = '" + Request.QueryString("AssignmentID") + "'"
var rs = conn.execute(sql)
I keep getting different errors and I have been unable to find a solution yet. I know that I need to change the date format from the Java standard to the one that SQL likes.
Help....
Norm...

Please tell us where the Java part of this comes in. I see that you are using JavaScript to load up data via an ADO connection (presumably on an IIS platform) - but I do not see where you are using Java

HP Officejet Pro 8600 "Problem with Printer or Ink System'

A gander at this forum suggests I am one ofa multitude of people perplexed by this issue. There is a notation beside one enquiry which says 'Problem Solved'.... well it isn't for me. My printer (typical!) is one month out of warranty. I had to replace the black cartridge and, when I did, it came up with this error prompt. I then replaced all the other cartridges. HP suggests removing the printhead and following that they say place it 'upside down on a clean sheet of paper'... NO instructions for cleaning it!! When it is replaced in the printer they suggest you 'rock the printhead left and right to make sure that the printhead fully seats in the carriage' and if THIS doesn't fix things 'try reseating the printhead up to 3 times'... This in itself is an admission of an 'issue' with this product. It doesn't sound like a very scientific engineering 'fix' to me!
A new printhead costs almost what we paid for the printer a year ago. I hate consigning anything to landfill that I can avoid... unfortunately it looks like that is where this unit belongs...

Hi @Robin_Perth,
Welcome to the HP Forums!
I am sorry to hear about you getting the problem with printer or ink system error, with your HP Officejet 8600, but I am happy to look into this for you!

Thanks so much for replying to my post. I tried the fist suggestions and they did not work. So, I attempted to move on Dow to the cleaning of my printer. I am the the first to admit that I'm not the genius when it come to electronics buys, my printer do not seem to have what is described in the photos. I'd like to upload a photo of my ink cartage but do not know how.
Charleshia, you can upload a photo here to reply. Click Reply, then on the window you'll see the image below..
click the one which has the red box, it's where you insert the photo
Going back on your issue.. the basic step would be.. take out the inks then close the door... what error message you got? If it's saying "Missing Ink Cartridge" just hit OK. Unplug the power cable at back of the printer, plug it back in.. Clean the copper contacts on the ink cartridges using a lint free cloth then reinstall them. Let me know if it resolved it or not.. I can only give basic troubleshooting here

Facing problem with a date column in select query

Hi,
I am facing problem with a date column. Below is my query and its fainling with " invalid number format model" .
Query: SELECT *

LAST_UPDATED column is "DATE" data type.
Please help me Thanks

You do not need the TRUNC here in any case.
I don't think so. What if the user wants only data for 22nd May and the table has records with date later than 22nd also? In that case your query willl not work. In order for the Index to work, I think the query can be written like this I think Sean is right though. Use of TRUNC Function is quiet useless based on the condition given here, since the to_date Function used by OP will always point to midnight of the specified date, in this case 22-05-2009 00:00:00.

Hi! I´m having problems with showing video files in Qlab on my Macbook Air. A sound/video technician told me to "blow out" my Mac. Was told to use cmd+ r when restarting. Is this the right way?

Hi! I´m having problems with showing video files in Qlab on my Macbook Air. It started suddenly. Consulted a sound/video technician who told me to "blow out" my Mac. Was told to use cmd+r when restarting. Is this the right way to clean up my Mac? And is it likely that some kind of bug is causing problems for Qlab to show video files? I´ve already tried with a bunch of different video files and sometimes Qlab plays them and sometimes not. I need the Qlab playlist for a theatre show and only have a week until showtime so starting to really worry. Is there anyone out there who can help?

Your Mac runs maintenance in the background for you.
Command + R gives you access to restore, repair, or reformat the drive using OS X Recovery
No idea why that was suggested.
You may have a third party video player installed that's causing an incompatibility issue.

Problem with loading data to Essbase

Hi All,
I have a problem with loading data into Essbase. I've prepared maxl script to load the data, calling rule file. The source table is located in RDBMS Oracle. The script works correctly, ie. generally loads data into Essbase.
But the problem lies in the fact, that after deletion of data from Essbase, when I'm trying to load it again from the source table I get the message: WARNING - 1003035 - No data values modified by load of this data file - although there is no data in Essbase... I've also tried to change the mode of loading data from 'overwrite' to 'add to existing values' (in rule file) but it does'nt help ... Any ideas what can I do?
