How to read a alv grid row data from standard program

Hi All,
I am working on transaction LBK1. Actually when you will open this transaction in the left hand side it will show you the data in tree. When you click on a notification node it will show the relevant data in right side. In which there is a operation tab . In this tab the data comes in alv grid. If user selects a row then I have to get that selected row value. There is also a toolbar above on the tree side. There are some buttons which execute our implementation class where I can put the code.
Can anyone please help me out? How I can read that selected row in our class/method?
Thanks in advance.

Setting and getting selected rows (Columns) and read line contents
You can read which rows of the grid that has been selected, and dynamic select rows of the grid using methods get_selected_rows and set_selected_rows. There are similiar methods for columns.
Note that the grid table always has the rows in the same sequence as displayed in the grid, thus you can use the index of the selected row(s) to read the information in the rows fronm the table. In the examples below the grid table is named gi_sflight.
Data declaratrion:
DATA:
Internal table for indexes of selected rows
gi_index_rows TYPE lvc_t_row,
Information about 1 row
g_selected_row LIKE lvc_s_row.
Example 1: Reading index of selected row(s) and using it to read the grid table
CALL METHOD go_grid->get_selected_rows
    IMPORTING
      et_index_rows = gi_index_rows.
DESCRIBE TABLE gi_index_rows LINES l_lines.
IF l_lines = 0.
    CALL FUNCTION 'POPUP_TO_DISPLAY_TEXT'
         EXPORTING
              textline1 = 'You must choose a valid line'.
    EXIT.
ENDIF.
LOOP AT gi_index_rows INTO g_selected_row.
     READ TABLE gi_sflight INDEX g_selected_row-index INTO g_wa_sflight.
    ENDIF.
ENDLOOP.
Example 2: Set selected row(s).
DESCRIBE TABLE gi_index_rows LINES l_lines.
IF l_lines > 0.
    CALL METHOD go_grid->set_selected_rows
        exporting
          it_index_rows = gi_index_rows.
ENDIF.

ALV Grid row selection possible options

Hello Experts,
I have an ALV Grid output with rows color codes based on certain status for each rows.Now when the user selects one or more lines to do the next process, what happens now as sap standard is the selected lines becomes highlighted ( kind of yellowish) and the selection button gets pressed.
But what the user is requesting is ,lets say he selects one blue and another red line, then both becomes yellow (because of the SAP standard highlighting) ...he would like those line colors to be still red and blue and only the selection button pressed.
Is there a way to do that is ALV grid? I'm trying to convince him to look at the status colum if he gets confused with what colors he selected or I will have to use a checkbox field as the first column and and hide the ALV selection option.
But was curious to find if this is possible in ALV?Or any other suggestions to handle this requirement is welcome.
Mat

Hi Mat,
I am curious if your user is so arogant when he buys a car too. Does he say to dealer "Sorry I don't want this gear lever to be placed here and here, I want it a litte bit higher. Can you please fix that?". This sounds like you are struggling with dumb user. I have never heard of someone complaining that the standard highlight is in wrong color. You already provided to him row colors, right? I think most of the users would be hugging you for such facilities.
I think in your case as the user is inalterable you should go for the checkboxes as you say. This way maybe you will somehow satisfy his needs (as the row colors will be kept even during selection). Personally I wouldn't bother such requirements. As long as the program reports correct data, he should not complain at all.
Good luck then
Marcin

ALV grid row mark

How can I create an alv without creating it with edit mode? I only want to have the columns to mark the rows but without editing function.
I don't find it in structure LVC_S_LAYO. At the moment I take
gs_layout-edit = 'X'.
but then I can edit all data, I only want to select with the row column, is that possible?

Use:
LVC_S_LAYO-SEL_MODE = 'A',
You have to switch editing off, otherwise it may overwrite this setting.
Then, to get what is selected use one of the methods:
GET_SELECTED_CELLS
GET_SELECTED_CELLS_ID
GET_SELECTED_ROWS
GET_SELECTED_COLUMNS

Eable indivadule cells editable by selected ALV Grid rows.

Now i encounter the case that in an ALV Grid list, the value column A can be entered by user if cell is blank in some rows.
.user will click on an EDIT button to make these cells editble for input value. is it possible to implenment the case?
BTW, I used the FM 'REUSE_ALV_GRID_DISPLAY' to generated the ALV list.

Hi,
First set the field catalog's EDIT field to 'X'.

Hiding zero in ALV(Particular Row/Column alone)

I use ALV Grid for displaying the output in the tabular form. It has one key field and 4 numeric fields. Always it will have only 7 rows. Now I should not display 0 if the row 4 does not have any values(Since it is a numeric field, by default zero will come). Rest of the rows should contain zero value if there is no value.
If I should not display zero for all the rows, then I can simply pass no_zero = u2018Xu2019 in the field catalog. But this should happen only for the particular row (4th row alone). Please advise me.

I am posting a example code, in this some paticular cells of ALV Grid are in editable mode. just analyse this example this may help you..

Multiple Hotspots in a ALV Grid single column

Hi Experts,
My ALV Grid report output looks like below....
If you observe below output, column 3 has multiple documents each one separated by ' ; '. Now, I would like to assign hotspot on each documents like DOC1, DOC2, DOC3, etc.
Heading#:          COL1 | COL2 | COL3 |
Records1:              1      | xxxxx | _DOC1_ ; DOC2 ; *DOC3*
Records2:              2      | xxxxx | _DOC1_ ; DOC5 ;
I know, we can assign hotspot for entire column. but my requirement is multiple hot spots in a single column.
Please help me on this?
Thanks in Advance
Raghu

As I mentioned earlier,
My ALV Grid report output looks like below....
Heading#: FIELD1 | FIELD2 | FIELD3 |
Records1: 1 | xxxxx | DOC1 ; DOC2 ; DOC3
Records2: 2 | xxxxx | DOC1 ; DOC5 ;
If you observe above output, field 3 has multiple documents each one separated by ' ; '.
When I click on DOC1, it supposed to display related picture on the POP-Up Screen. Similarly when I click on DOC2, it supposed to display that document picture on POP-up screen.
Before going to do this, first I need to assign hotspots on each documents like DOC1, DOC2, DOC3, etc.
Please help me.

Alv grid background column headings

HI EVERYONE,
I was able to execute the ALV grid report in background .But columns heading is reeating for
each page.
Can't we just just have the Column Headings once for all pages.?

For the IS_LAYOUT parameter it is possible to set NO_COLHEAD = 'X'. Then the header is gone. Then you have to create first line in table with texts. But then all fields must be character fields.

Hierarchical ALV - enabling row/column input

Hello,
I'm going to incoporate the hierarchical ALV in a report. Let's say I have 5 item rows for a header row, is it possible to make individiual rows input enabled? Meaning, of the 5 item rows, I wish to make two of them editable, but not the other three.
I've done the standard ALV and made columns input enabled when building the fieldcat, but this applied to all rows, which I don't want in my scenario.
Any help would be appreciated.
Thanks

Hello,
Input enable is a parameter of fieldcat but you have to specify the internal table that you used in header row or item row.
You create a data ZHEAD and ZITEM that you transfer in fieldcat data "table"
Don't forget the clear when youo fill this internal table

Can i raise any event on the ALV GRID row selection.

Hi All ,
Is there any way to trigger any event upon the selction of the ALV GRID rows?
Suppose i have 2 grid controls 1 for Header and the other for corresponding line items . I would have already the header data (differnt document headers) populated , upon selecting (i don't want any user click or button click) one of the header i want to do some changes to the corresponding line times for the header data selected...
Please give me some tips on how to go about on this .
Thanks,
ALFH

how the user will select , since you dont want user click or button click?
one option is to have hotspot, but again user has to click .

ALV grid Row Height

Is it possible to adjust row height of alv output? I have a grid being displayed on a touch screen and it's difficult to choose a row. I want to make them about double the height on display.

Hello Michelle
There is no possibility to change the row height. The only possible way I see would be to reduce the resolution of the touch screen.

How to set different row - column visibility attribute

Hi all:
 I have one table in webdynpro for java. For example it have 4 rows, I need to set one column as different visible for row 1st and row 2nd .
 column1 column2
row1 x -
row2 - x
Can I set it ?
Thanks a lot.

ya sure, u can
make a visibility element and assign it to the tablecelleditor of each column of ur table. Now in the code, u must have bound the table to a node, make the visibility element in the same node. Whichever row u want to make invisible, write the following code:
wdcontext.node<nodename>.get<node name>elementat(<the row which u wish to make invisible>).set<visibility context>(wdvisibility.NONE);
it will work.
Let me know if u need further help....
All The Best!!!
