ALV: F4 help for a column wanted, but without any check

Hello,
I have an ALV and I use a DDIC structure for the field catalog. My requirement is that for all columns in ALV, the F4 should appear normally (using the DDIC information), but I do not want an automatic check for the value entered by user.
So .e.g. if in F4, possible values are 1, 2, 3 then the ALV throws an error if user leaves the field blank (because blank was not a possible value for the domain of the field). How, can I by-pass this automatic check by ALV (while still keeping the F4 help)?
Regards,
Mohit

Hi hope u know the difference between value table and check table.
In this case you have to give value table as F4 reference but not check table.
I mean consider the field Plant. if you are defining plane with reference to master table T001w and u r entering a value not in T001W it will give error. because here it is check table. where as define the plant with refence to MARC. then MARC will be value table. and dont give error if you enter any plane value not there in MARC.
Try to find out value tables for your fields and use. Then it will work.

ALV: Search help for editable column using OVS/Input Help Component Usage?

Hi all,
Is is possible to assign a value help like OVS or "Input Help Component Usage" to a editable ALV column using Web Dynpro?
Thanks and regards,

Hi Madhu,
Than I must have made something wrong because this is exactly what I've tried.
I'll check my freely prgrammed value and the assigning again.
Thanks a lot for your quick reply.

But for table column I am unable to find..
Help me regard this...
Thanks & regards,

Hi,
In debugging , the I have seen the node info attributes list ( VALUE_HELP_ID and VALUE_HELP_MODE ) .
For you understanding, Here I am giving the values which contains ,
VALUE_HELP_ID contains the AUTO:VBUK
                                                AUTO:VBUP

Rating enigma: library recreated with all playlists but without any rating!

Dear all,
My external HD has crashed, but I got to recuperate all my music files (150 GB).
The library files are intact, as they're stored in my internal Mac drive (users/my name/music/itunes folder).
I already added all the files from the new drive into Itunes and already got to recreate the library (importing the main xml file to Itunes: file > library > import playlist).
The playlists (around 1000!) were recreated without any problem but the ratings are not appearing (all my music files were rated!). Do you know can I solve this enigma? I already did the standard procedure twice (file > library > import playlist), but without any success.
Those ratings are very important for me, as I have many automatic smart playlist linked to that!
So, your help is highly appreciated,
Alberto Mathia

Hi friends:
OK, I prepare a new exp/imp, but befoe doing that, I want to identify all errors happened in previous exp/imp
1. I set statistics=none in exp par file, now I have a clean export without any warnings. :-)
2. I checked previous imp log, found the below problem
1)

instance. while, we can set grants=n in the later imp par file.

like,
alter tablespace RPT_IRTB
Add datafile '/cma7/appl/oracle/dods/dt_irtb02.dbf' Size 64M;
why still have this problem? is there anything I can improve, please advice?
3) ORA-2000 unable to set values for xxxx (object), doesn't exit or insufficient privileges.
(do I need to set user as sys in the future imp par file)?
for the database link problem, I will check after the above problem resolved.
Thank you very much

After updating to 12.1.2.27, songs play, but without any sound output to internal iMac speakers

So i updated to 12.1.2.27 and songs 'play', but without any sound output. Checked my audio settings and had it at Internal speakers. Checked the speakers (they work, at least for YouTube vids), restarted machine, etc and no audio output from iTunes. Any suggestions? Am I missing something?
Thanks in advance

Try unchecking Sound Enhancer and Sound Check in your Preferences under Playback
Sound check may have reduced everything to a low output level inadvertently.

something went wrong with my apple tv and now it says that it is in retail demo mode. How can i fix it? I have had it for more than one year without any problem

To turn on/off retail mode, go to settings, general, legal.
Do not open legal, just put the cursor there.
Then, on the remote, type this sequence : right - right - left - center.
The AppleTV should reboot.

Help for adjusting columns of a JTAble in a Table Model

Hello community,
In order to have a good display of by DataBase in a JTable, I've wrote some code to adjust columns in function of datas. Those datas are displayed with a TableModel ( which I've declared in a class JDBCAdapter ).
When I start my application, I call adjustColumns(), and all is great but when I add information to my DB and display it, the columns of my JTable return to default width...
So I want to incorporate my function adjustColumns in my TableModel, and I need help...

Hi,
OK. I have read your code sample again. It looks like the JDBCAdapter class is reloading table data in the executeQuery method. Why not call adjustColumns at the end of this method after the new rows and columns are loaded? Perhaps it also should be called at the end of executeUpdate. Have you tried doing that?
I would still set
JTable1.setAutoCreateColumnsFromModel (false); to prevent Java from readjusting the size automatically at some other time.

Terry

F4 help for a column in tableview

Hi all,
I have achieved F4 help using java script for input field, but i want to use it to fill each value of a column, i am using iterator for the column properties. Is the method of displaying help same as used for input field. I want to do it without using the concept of MVC.

Photoshop CS6 stopped working. Cannot open it. Bridge opens, but without any of my files populating it. HELP

Photoshop CS6 will not open any longer. Clicks on the icon on the desktop do nothing. Yet I was working with it yesterday. Bridge opened with my files populating it. I turned off computer hoping CS6 would reset. CS6 still does not open, but now Bridge opens without any of my files. Please HELP.
I am using Windows 7, 64 bit.

Moved to Photoshop Forums

ITunes opens but without any text showing. Drop down menus have text but not the app itself. I have a Mac Powerbook Pro running Windows XP under Boot Camp.

Running under Windows XP, a few upgrades ago iTunes started opening without any text showing in the application. Clicking on PLAY will play music but no text shows to indicate what's playing and no text to show music library. Drop down windows show text but not the app itself.
Subsequent upgrades and reinstalls have not corrected the problem, When I run under iOS (Snow Leopard), iTunes opens with text and runs correctly.
Help!

Because I created FAT32 partition using Boot Camp tool few days ago I installed my custom copy of Windows XP with SP3, IE7 and WMP10 integrated using nLite (for WMP10 integration use RVM Integrator). I did not use Boot Camp tool this time - I just booted CD using Option key. Then I installed Boot Camp 2.0 drivers you can find on Mac Disk 1. After this I installed Boot Camp drivers 2.1 update. In Add or remove Programs I checked drivers - I uninstalled old drivers which call identical, but you can skip this. Everything works fine BTW it is better to format your partition to NTFS - you have much less disk errors, you do not waste time for disk errors scans during Windows startup, your data are much more safe. If you need NTFS write permissions use great tool Paragon NTFS for Mac OSX or open source NTFS driver.

Is it possible to export my bookmarks from Firefox and import to another instance of the browser but without any type of cookie being imported?

For convenience I want to have my already created bookmarks imported into another Firefox user's browser. For security reasons I don't want any cookies or flash cookies to be imported when I do this and I don't want to Sync browsers. Is this possible? If so, how, or are cookies not part of the exporting of bookmark data anyway?

You can transfer bookmarks using two different formats:
* Backup format: if you want to preserve tags, this format can do that. However, the Restore process completely replaces all existing bookmarks with what is in the backup. If you want to merge different sets of bookmarks together, do not use this method. More info:
** [[Restore bookmarks from backup or move them to another computer]]
* Export format: with this option, Firefox creates an HTML file with an ancient format compatible with most browsers. It is not as complete as the newer Backup format. More info:
** [[Export Firefox bookmarks to an HTML file to back up or transfer bookmarks]]
** [[Import Bookmarks from a HTML file]]
Neither of these files contains cookies or passwords.
