Reading fields from ALV display

Hi All,
I have a check box in front of each data record in the ALV display. This check box is editable. The user will check some records after seeing the details and click on a puch button provided. On the click of this button I need to read all the records whose check box has been checked.
However, this edited value of check box is not getting reflected in the program. Is there any FM or any other method through which I can read the changed values in the ALV display ??
Request your urgent help.
Thanks and Regards,
Archana.

Hi ,
Please see this example program - BCALV_EDIT_05
I am sure this will help you.
If u have used standard ALV function module(REUSE_ALV_GRID_DISPLAY) instead of class cl_gui_alv_grid , then you can set layout and fieldcatalog accordinglly.
dont forget to add filed
checkbox type c.
in your display table (itab).
fieldcatalog setting :
for field : 'CHECKBOX'.
<b> ls_fcat-checkbox = 'X'.
ls_fcat-edit = 'X'.</b>
In user command subroutine :
check displayed internal table (itab here)
u will find the checkbox-checked record has itab-checkbox = 'X' .
Regards,
Mihir.

F4 for Editable field in ALV, display Name but capture ID

Hi Friends,
I have a ALV for which i have defined a Structure, which is passed to Fieldcatlog.
I have defined a Search help - ZUSER_NAME which has following fields to display.
USERID - USR02-BNAME
FNAME
LNAME
FULLNAME
So my structure for fieldcatalog has User-id which is linked to this search help with Domain XUBNAME.
So in my report i made this User-Id as editable and F4 available, everything is working fine.
when user does a F4, its displaying Userid,Fname,Lname and complete name.upon selection and save i am capturing the id and storing in the ztable.
But now i have a requirement that when user selects a value from this search help on F4, i need to display Fullname but capture the User Id. How can i do that?
This is something similar to the one we have in BSP- key-value pair.
how to do this in ALV.
Appreciate if someone can guide me thru.
Thanks,
Simha

Hiding some fields from ALV report

Hi All,
I want to know if there is way to hide certain fields in ALV for some users only and not for others?
If I use the option NO_OUT = 'X' it will not be displayed in the list but the user can see the in the Layout option fields but if use NO_OUT = 'X' and TECH = 'X' the field will not be in the list and in the layout also but other users will miss that field.
If I create user specific variant, but once the user is in the report he can change the layout so certain fields cannot be hidden.
So, is there any way to hide some fields for certain users and not for others without hard coding user ids in program and restricting the fields from display??
Thanks in Advance.
Sonali.

Thank You Vijay for the reply.
I knew that Authorization object was the final solution but before using it I wanted to find out if there was a way in the ALV report to restrict certain fields.

Tranfering data from alv display to a transaction with table control.

Hi all,
I am having some problem transfering data from my alv display to a trasaction which needs to display some values in a table control base on criterias which I have selected from my alv report.
When selecting an entry in my alv report.
1. The program should check whether there is an entry in a z table(already created), if so it retrieves data fro the z table base on the selected criteria.
2.otherwise it search from the data from other tables and then saves it in the z table and display the values in the tc.
my program is as follows.
FORM button_click USING p_ucomm TYPE sy-ucomm
                        p_selfield TYPE slis_selfield.
CASE p_ucomm.
    WHEN 'SALES'.
      READ TABLE gt_alvdisplay
      INDEX p_selfield-tabindex
      INTO gs_alvdisplay.
      SET PARAMETER ID: *I dont know how to pass the para to the tc.....
      CALL TRANSACTION 'ztrans_test".
ENDFORM.
Note: TC is already created and it retrieves data from the z table but am having prob just to pass the parameters.
Ill be very grateful to you all

Hello,
Yes you can create text field without using screen painter as follows:
PARAMETERS P1 TYPE CHAR12 MEMORY ID mid.
Here, this code will create text box with name P1 and parameter id "mid"
You can assign meaning text to p1 using menu link GO TO --> TEXT ELEMENTS --> SELECTION TEXTS.
So before call transaction which contains this field you can write below statement.
SET PARAMETER ID mid VALUE <value variable>.
* Here vlaue variable is the variable from which you want to pass value to parameter id mid.
Refer [SAP Help|http://help.sap.com/saphelp_nw70/helpdata/en/e7/deb237b9a9a968e10000009b38f8cf/frameset.htm] for more information.

Hide a field in ALV "Display Details" list

Hi Experts,
I have a requirment where I have to hide a field in ALV output, as well as in "Details display". I already put NO_OUT = 'X' for that field in fieldcatalog itself. It is hidden in the ALV output anyway, but the problem is when user selects a row and clicks on "Details" button in toolbar of ALV, it still displays the hidden fields of that ALV list with/out headings there.
Hope you understood my problem, pls respond soon if you hav any solution for this?
Thanks

Quantity field in alv display

Hi all.
we are phasing a problem.
I am using alv to display in output.
I am using a Quantiti field (BDMNG),.
in this field if nodata is there then it is showing 0.000(that is the default value).
I don't want those zeros.I want only space(blank only).
Can any body help me to solve this issue.
Thanks in advance
Eswar.

Hai,
While building field catalog For quantity field Set the NO-ZERO attribute to 'X'.
Or you can change the quantity filed to character in the alv display.
Mark points if helpful.

Reading fields from a text file

Hi, I'm fairly new to this so bear with me.
This is for an assignment - the idea is to cretae an online system for booking seats at a cinema - haven't got past the login stage yet?
I've got an applet that needs to read in a field from a text file.
I'm using the StringTokenizer function.
I've put a test in to check that the applet can find the file, which seems to be ok.
However, it's not reading from the file.
Te file is a simple text file - fields are seperated by a comma and a space.
Any ideas?
Please help as this is quite urgent.

Guest, , Guest,
To test that it is working, it should just put a message in the Text Area, but nothing happens when you press the "go" button.

1. Your applet will not work, because it is trying to
read file from local disk.
2. This task can be solved by simple CGI script
(which is much more common and universal thing than
java), so you do not need to use java if you want to
send 3 lines to a server.
3. See examples and read some books.1. Stated the obvious.
2. This is a java forum, not Perl.
3. Pathetic and patronizing.
Very helpful.

(Swing) Reading fields from other forms - Best practice

Hi All,
I have been learning Java and Swing through NetBeans (quite a cool way to do it). I would like some 'best-practice' advice please. Google and search on this forum are normally my friends, can't find anything relevant for this though. I have created an application that seems to be functional, all my navigation is through tabs.
To make my app portable I have created a ?Settings? part. To save having another tab, I have basically copied the way NetBeans deals with opening the ?About Box? in its example, and have set-up fields in here. This essentially opens a JDialog with fields through an option in the menu.
I figure the best way to store the data is in a simple text file, and have the application read the values on start-up? Then when somebody changes the fields and saves it just overwrites the text file with the new values. I am not sure how to best read these in though, I can?t find a way of reading direct from the JDialog (i.e. var.getText()) which makes sense as the JDialog will be closed.
Will my best practice simply be writing a class which reads the file, then whenever I need a value just calling the class?
Thanks a lot

You should not be using preference files unless you really know what you are doing. This is one area of the very few areas of Java programming that can have lasting nasty negative affects on a computer that runs the code if done wrong.
If you want the user to save preferences it is better to just use xml. The advantage of preference files is they can be used by multiple programs and are permanent even after the program is done running/deleted/writen-over/forgotten. The disadvantages of preference files is they can be used by multiple programs, are permanent even after the program is done running/deleted/writen-over/forgotten, can cause damage to your OS, may be seen as harmfull by add blockers and/or anti-virus software, may lead to conflicts with other software that uses similar naming schemes, and are pretty much unportable.
You are going to be much better off in the long run learning XML and just saving them there, an added benefit of XML is if you screw something up and it causes your program to no longer run you can easily edit the xml by hand.

Leading zero for a character datatype field in ALV display

I have field access sequence value(VAKEY) which is concatenated by sales org, distibution chnl and division
(0100/01/01). the field is populating proprerly in internal tables, but in ALV display it is displaying as 100/01/01. How to consider leading zero in ALV for a CHAR datatype field.
Thanks in Advance.

Hi Srnii,
You can use the below sample statement
Shift mara-matnr right deleting trailing ' '.
overlay mara-matnr with '0000000'.
Thanks,

Disable some standard buttons from ALV display

Hello All,
I am creating an ALV display using object oriented approach. I know how to exclude some of the standard function buttons from the list.
But suppose instead of deleting, the requirement is to disable (I mean grayed out)
some standard buttons from ALV. Could anyone please comment on how to do this.
Many thanks in advance.
