Multiple selection with F4 help in webdynpro

Hi all,
Is it possible to create F4 value help for a field in webdynpro which will support multiple selection?
If the user selects multiple entries, then a new input field will automatically be inserted. Much like F4 help on BW Web Templates.
Thanks,
Satyajit.

Hi Satyajit,
Here is the link to the tutorial which Pran is talking about
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webas/webdynpro/tutorial on advanced value help and object value selector - 9.htm
and see the link below also which discusses on the listener events

Hello,
you can use the * for wildcards in the BEx Web.

Possibility for multiple selection in F4 help

Hi,
at the moment I have to change the marketing attributes in PCUI. We need a functionality that allows us to select multiple values in the F4 help and depending on the amount of selected values the amount of entries for marketing attributes will be generated.
Is there a possibility to realise a multiple selection in F4 helps?
What needs to be done?
Would be great if you could help me.
Kind regards,
Timo

Hi Naveen,
thanks for your help. Just to be sure, I meant a standard simple F4 help using F4_main.do. Is it somehow possible to change it there for one specific F4 help or do I need to develop a complete new BSP application for it? The BSP application I'm talking about is not a custom developped application but generated through F4_main.do
Kind regards,
Timo

Multiple Selection in F4 help

Unlike BSP, WebDynpro have a very nice integration of F4 helps from DDIC.
I wonder if F4 helps also support multiple selection.
So, can the user select multiple lines in the result list, and transfer all back to the calling screen?
How can I switch this on in the F4 help? By setting the cardinality of the context node?
How is the selection transferred back to the calling screen?
Must there be a table with multiple editable lines, into which the selected elements are transferred? Or can retrieve the selected elements programmatically?

Hi daniel ,
You can do your requirement in one more way by implementing the Search help exits .
For eg :
Search Help PREM will give the list of Employee , but you want only the employee with the status 'Active ' in this case you can create a serch help exit .
Create seach help exit.
Take z copy of Function module F4IF_SHLP_EXIT_EXAMPLE .
Declare all the Parameters "see some example by using where used list
inside that FM you can find the piece of coding . uncommend thePerform and write your logic inside the perform
IF CALLCONTROL-STEP = 'SELECT'.
   PERFORM STEP_SELECT TABLES RECORD_TAB SHLP_TAB
                       CHANGING SHLP CALLCONTROL RC. " write your logic in this perform
   IF RC = 0.
     CALLCONTROL-STEP = 'DISP'.
   ELSE.
     CALLCONTROL-STEP = 'EXIT'.
   ENDIF.
    EXIT. "Don't process STEP DISP additionally in this call.
ENDIF.
For formatting your Result internal table . pass your final int table to below mention FM
*Formating the result table
CALL FUNCTION 'F4UT_RESULTS_MAP'
* EXPORTING
*   SOURCE_STRUCTURE         =
*   APPLY_RESTRICTIONS       = ' '
TABLES
    SHLP_TAB                 = p_shlp_tab
    RECORD_TAB               = p_record_tab
    SOURCE_TAB               = LT_PA0002   " Final internal table
CHANGING
    SHLP                      = p_shlp
    CALLCONTROL              = P_CALLCONTROL
EXCEPTIONS
   ILLEGAL_STRUCTURE        = 1
   OTHERS                   = 2

Multiple selection in F4 help in table control

Hi,
I am providing F4 help for a particular field in the table control. User must be able to select multiple values from this F4 help this is done using the function module F4IF_INT_TABLE_VALUE_REQUEST. Now the selected fields have to be transferred to screen, this is done using FM DYNP_VALUES_UPDATE.
My problem is i have 6 rows displayed in my table control. So only first 6 values from the user selected values are getting updated in my screen fields others are not getting updated. Say if the user selects 10 values out of them only 6 is populating in the screen. How do i get the others also? Please help.
Thanks,
Karthik

Hi,
Check the Following threads
can we select multiple entries from a F4 result?
Table Control dynamic F4
After you select Multiple rows from F4 Help these are stored in RETURN table.
Now in main program modify the Internal Table.
In PAI
loop at itab.
" You can not handle this in this Loop
endloop.
module modify_from_f4
process on value-request
field fname module get_f4 " Here you get the F4 Help and the values are in RETURN tab
in Program
module modify_from_f4.
" in this module you can use the RETURN TAB like
loop at itab
read table RETURN with key fnam = itab-fnam " and get the corresponding value and modify itab from RETURN tab
if you can not find common fields and just want to pass the values then
read table RETURN INDEX SY-TABIX. " IF the Itab is empty then follow below loop
endloop.
loop at return.
move return-fieldvalue to itab-fnam
append itab.
endloop.
endmodule.

Multiple Selection of Search Help

Hi Guys,
I've read SAP's note that:
Multiple selections in the search options is not supported when you use the search help control. If you need these selections, you can also use the list mode SAP GUI for HTML:
Select the 'Help->Settings ->F4 Help' menu option to access the dialog box where you must then choose 'In modal R/3 dialog box' as the display option.
However, this setting is only user-specific. Is it possible to make it system-specific? i.e. enable it for all users?
THanks,
Zhenmin

Hello ZhenMin,
Yes, you can make it the system default or change it for all users by doing the following:
1. to make "Dialog (modal)" the system default go to SU52, Parameters and then add parameter name "F4METHOD" with a value of "NoActiveX"
2. to change the value for the current users go to table USR05 and change the value of the field "F4METHOD" to "NoActiveX".

Multiple selection with control key in ring, enum, or radio buttons on Speedy-33 ?

Hi all,
I want to create a list of entries via ring, enum, or radio buttons. I just want the user to be able to select more than one entry from the list.. This is normally doable with windows applications by using control key. However, how could I do the same thing or let the user choose more than one entry from the list? Any idea is greatly appreciated..
Thanks so much!

Hi Casiopea -
To answer your question, I'm not sure I've ever actually seen a ring, enum, or radio button control exhibit the "CTRL+click" behavior you're describing. (In fact, I think all of those user interface elements are designed specifically so that only one value can be selected at any one time.)
However, I have seen plenty of list boxes allow multiple selection, and LabVIEW's list boxes can do the same. A group of checkboxes can also end up looking like radio buttons if you group them with some "decoration" and would allow you to select multiple options (because you can check/uncheck each box independently).
I'm not quite sure, though, how your question relates to LEGO specifically. Did you accidentally post this question to the wrong discussion forum?
To address Eagles Coach's statements, the official Move block uses checkboxes in the "Port" section of the configuration pane in the MINDSTORMS software, not radio buttons. The Motor block uses mostly radio buttons, and I didn't see any sections that allow multiple selections.

Multiple Selection with JCombo Box

I want to make a multiple - selection JComboBox enables the user to select many items from JComboBox and copy items from one JComboBox to another.How can I do this?

Hello,
ComboBoxModel allows only single selection. It's better to use a JList instead because it isnt worthwhile the effort to create another multi-selection model.

ITunes 9.2 stops adding multiple artwork in multiple selection mode. Help?

Hi everybody,
Since 2003 I've been using iTunes and adding multiple artwork in several tracks at once.
Lets say: I added 10 tracks of a CD to iTunes library, then selected all of them and then right click to choose "Get Info > Multiple Item Information". Then I just dragged and dropped as many artwork pieces as I wanted onto the artwork window, one by one. Clicked OK and voilá.
Now it will only accept one artwork. Following the procedure I used to do, now it will only take the last artwork I place onto the artwork window.
Now the only way to get multiple artwork in a CD is adding all the artwork (lets say the 20 pages of the booklet) one by one in "each track" separately!, which is a pain in the neck.
So now I have to add artwork one by one to each track one at a time.
Is there a NEW way to add multiple artwork on multiple tracks at once in iTunes 9.2?
Screen shot: http://grab.by/51UT
Thank you for your help.

Hi- you might've already figured this out on your own, but:
A) add the first artwork picture (what you want for your cover artwork) using "Get Info > Multiple Item Information" - and close the Multiple Item Information window
B) with the multiple tracks still selected, drag your additional artwork picture items into the artwork panel in the lower left corner of the iTunes window (this is the artwork panel titled "selected item").
C) your additional artwork will be added to all of the selected items. You can click through the artworks using the left/right arrows above the artwork panel.
Obviously you can also use this same method to add that same additional artwork to any other tracks, from other albums, etc. simply by selecting them as well.
Side note, the easiest way to select all tracks from a single album: select the starting track, then use ctrl-shift and select the ending track- all tracks between those two will be selected.
Aaaaaand you're done! Hope this helps!

Multiple Selection with JList

Hello!
I have a Frame with a JList that needs to be able to do multiple slection. The JList ist filled with special names which are found when the user opens a certain file. (so a file-chooser is here too) When the User selects a name every paragraph containing that name should be posted in a textarea.
However, when i run the program I can select multiple items, BUT it just recognises that the user selected one of the items, and I think it's the first one clicked.
How can I change that? I have used getSelectedValues() but it just won't work...
Can someone please help?
Thanks

So getSelectedValues() is only returning an array of size 1?

New to a Mac in general and having multiple issues with iTunes - Help?

So I bought my first mac for design/marketing uses (flyers, video etc) and figured I'd consolidate my wife and I's iTunes stuff to it as well...So far most things are done but I have a few snags.
In moving everything over I knew I would end up with a lot of duplicates, we both had a lot of the same music via the CD's we own. The process I did was I connected the external drives from my machine and my wifes machine to the Mac which already had an external blank 200GB drive connected to it and iTunes was setup to use that drive as the music folder location. I then added all the music from the external drives from my machine and wifes machine to iTunes one at a time. I then imported the library playlists etc and changed the path in the files from "M:\itunes music\" to "file://localhost/music" ... This worked, all playlists are back and work.
For handling duplicates on my windows machines in the past I would sort to show duplicates then would go through selecting all duplicates (using ctrl key to select a lot at a time) then delete those in iTunes, it would ask to delete the file and I always had it delete the files because the files themselves were always duplicated (those file being songname1.mp3, songname2.mp3 etc). This worked for the windows machines...not so much for the mac. Apparently the mac didn't duplicate all actual files and instead created duplicate entries based on the same file in a lot of cases.
Snags:
It looks like the duplicates the mac is showing sometimes are showing multiple entries in iTunes for the same physical file, so If I delete the file, I'm deleting the only copy of the song. Sometimes though there are songname1.mp3, songname2.mp3 etc...This makes it extremely difficult to kill out the duplicates because now I have to look to see what file every duplicate is looking at before deciding to delete file or not...I would be sitting here for weeks on end to do that! I need a better solution.
Second snag that I think is related to the first. My iTunes library is showing 213GB's worth of music being stored on the 200GB drive. I think this is due to the duplicate entries using the same file...The library should be more around 140GB's. I just want to confirm this is indeed the issue or know if there is another place a mac would try to store itunes music if the music folder fills up?

Checkedlistbox allows multiple selections with Selection mode set to one

I have a simple CheckedListBox with three options. I set Selection Mode to One. When I test the form, it allows me to have more than one box checked. I can clear the other two with a program, but my understanding of Selection Mode was that it would not
allow more than one box to be checked if set on one.

Option Strict On
Public Class Form1
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
CheckedListBox1.SelectionMode = SelectionMode.One
For i = 1 To 10
CheckedListBox1.Items.Add("Number" & i.ToString)
Next
End Sub
Private Sub CheckedListBox1_ItemCheckChanged(sender As Object, e As ItemCheckEventArgs) Handles CheckedListBox1.ItemCheck
Dim ItemIndex As Integer = e.Index
For i = 0 To CheckedListBox1.Items.Count - 1
If i <> ItemIndex Then
CheckedListBox1.SetItemCheckState(i, CheckState.Unchecked)
End If
Next
End Sub
End Class
