Checbox in ALV modify a 'C' field in a internal table.

First at all, sorry my english...
Well, That's my question.
I have an ALV List. One of the ALV's fields is a Checbox and I want the next:
- When I click on this Checbox, it shows itself as marked. At this point; I want to modify a 'C' field on the intental table that's running under the ALV.
Some ideas?
I supose I have to handle some events from the ALV, but I'm not sure how to do it.
Thanks a lot!

Field catalog for internal table in ALV

In my program the internal table consists many fields from various tables and structure doesn't belong to a single data table.
In order to get output in ALV grid following FM has been used
REUSE_ALV_GRID_DISPLAY
for field catalog the fields are defined specifically.
l_fieldcat-fieldname = 'VBELN'.
l_fieldcat-outputlen = 10.
l_fieldcat-seltext_l = 'Billing doc'.
l_fieldcat-no_zero = 'X'.
l_fieldcat-hotspot = 'X'.
append l_fieldcat to p_fieldtab.
..............and so on for all the fields.
Just wanted to know is there any other method to display all the fields of this internal table automatically so each field is not specified specifically.

Colour to field in an internal table

how to colour a particular data in a particular field of an internal table.

See this
1. add one more field to ur final internal table say COLOR(4)
2. in layout wa_layout-style_fname = 'COLOR'. " if its grid
wa_layout-style_fieldname = 'COLOR'. "if its list
3. read table itab index 3.
itab-color = 'C410'.
modify itab index 3
4. see program SHOWCOLO for all color codes
1. Add a field of data type CHAR(3) to the internal output table.
2. Enter the color code in the appropriate field of the row to be colored in the internal
output table:
Code: 'Cxy'
C = Color (all codes begin with 'C')
x = color number ('1' - '9')
y = highlight ('0' = off, '1' = on)
3. Assign the internal output table color code field name to the IS_LAYOUT importing
structure IS_LAYOUT-INFO_FIELDNAME field and pass this structure in the ALV call
interface.
To enable row coloring, you should add an additional field to your list data table. It should be of character type and length at least 4. This field will contain the color code for the row. So, lets modify declaration of our list data table gt_list.
you should fill the color code to this field. Its format will be the same as explained before at section C.6.3. But how will ALV Grid know that you have loaded the color data for the row to this field. So, you make it know this by passing the name of the field containing color codes to the field INFO_FNAME of the layout structure.
e.g.
ps_layout-info_fname = <field_name_containing_color_codes>. e.g. ROWCOLOR
You can fill that field anytime during execution. But, of course, due to the flow logic of screens, it will be reflected to your list display as soon as an ALV refresh occurs.
You can color an entire row as described in the next section. However, this method is less time consuming.
Coloring Individual Cells
This is the last point about coloring procedures for the ALV Grid. The procedure is similar to coloring an entire row. However, since an individual cell can be addressed with two parameters we will need something more. What is meant by more is a table type structure to be included into the structure of the list data table. It seems strange, because including it will make our list data structure deep. But anyhow ALV Grid control handles this.
The structure that should be included must be of type LVC_T_SCOL. If you want to color the entire row, this inner table should contain only one row with field fname is set to space, some color value at field col, 0 or 1 at fields int (intensified) and inv (inverse).
If you want to color individual cells, then for each cell column, append a line to this inner table which also contains the column name at field fname. It is obvious that you can color an entire column by filling this inner table with a row for that column for each row in the list data table.
If it is in ALv refer the following code:

There are a number of ways to create a fieldcat.
For the purpose of this example i will build the fieldcatalog manualy
by populating the internal table fields individually and then
appending the rows. This method can be the most time consuming but can
also allow you more control of the final product.
Beware though, you need to ensure that all fields required are
populated. When using some of functionality available via ALV, such as
total. You may need to provide more information than if you were
simply displaying the result
 I.e. Field type may be required in-order for
 the 'TOTAL' function to work.

ALV - How to set selected rows into internal table

Hi all,
I am tying to set with an 'X' flag the selected rows in my ALV using an internal table that contains all rows showed.
More exactly I have tried to follow these steps.
1) I have added the filed SEL (type SEL) to my ALV structure zrt_bo_slabsend and I defined my internal table in this way
 DATA: gt_report TYPE STANDARD TABLE OF zrt_bo_slabsend,
 gw_report TYPE zrt_bo_slabsend.
2) I have set gw_layo-box_fname = 'SEL' to gw_layo (ALV layout)
Pressing the "delete button" that I have insert on the top of the ALV, I intercept correctly my user command and I call a form (named "delete_lines") where I have this abap code
FORM delete_lines.
 DATA: l_subrc LIKE sy-subrc,
 lw_grid_settings LIKE lvc_s_glay.
gw_layo-box_fname = 'SEL'.
 "set field name to store row selection
gw_layo-edit = 'X'. "makes whole ALV table editable
gw_layo-zebra = 'X'.
gv_repid = sy-repid.
call function 'REUSE_ALV_GRID_DISPLAY_LVC'
exporting
 i_callback_program = gv_repid
 i_callback_pf_status_set = gc_status
 i_callback_user_command = gc_user_command
 is_layout_lvc = gw_layo
 it_fieldcat_lvc = gw_fkat
 i_grid_settings = lw_grid_settings
 i_save = 'X'
 is_variant = variant
 it_events = gt_events
 TABLES
 t_outtab = gt_report
 EXCEPTIONS
 program_error = 1
 OTHERS = 2.
LOOP AT gt_report ASSIGNING <report> WHERE SEL = 'X'.
 DELETE gt_report.
ENDLOOP.
ENDFORM.
I'd like to select many rows in my ALV report, than by pressing the delete button I'd like to see a refresh of my ALV, without the selected rows. I want to save it only at the end of my action, only by pressing the save button.
Any suggestion about the abap code will be well appreciated.
Thanks in advance for your kind help.
Regards.

Dynamic access to the fields of an internal table

Hi,
Currently i'm having 10 fields in 1 internal table, and i need to validate this 10 fields but i dont like have too many "if and endif" statement. Is there any option to write an dynamic code.
Example
Data: begin of table,
 field1 type c,
 field2 type c,
 field3 type c,
 field4 type c,
 field10 type c,
 end of table.
Let say i want to fill field1 with 1, field2 with 2,........................... field10 with 10.
So instead of using this code
table-field1 = '1'.
table-field2 = '2'.
table-field3 = '3'.
table-field10 = '10'.
Can i do something dynamic like this
DO 10 times.
Dynamic coding, any idea ?

How to join fields from different internal tables and display into one int

hai i have one doubt...
how to join fields from different internal tables and display into one internal table..
if anybody know the ans for this qus tell me......

hii
you can read data as per condition and then can join in one internal table using READ and APPEND statement..refer to following code.
SELECT bwkey                         " Valuation Area
         bukrs                         " Company Code

Changing the order of fields in an internal table

Hi all,
I'm using field symbol as internal table. this table has got a standard database structure.
I want to make the 3rd column of this internal table as 1st colums keeping rest of the columns as it is.
Is there any way to do this?
Thanks,
Anil.

Hi
Instead of directly taking the type as a standard structure , declare the FS internal table as type of types structure.
Data: fs_scarr like type_s_scarr.
FIELD-SYMBOLS <scarr2> TYPE fs_scarr
In the types put the third column as first one and use into corresponding in select query
or else
while displaying the internal table change the order of the columns
Loop at itab into fs_itab.
write : col3
col2
col4
endloop.

Aggregate a numeric field in an internal table

Hi All,
I have a small requirement in ABAPit goes in this fashion
I need to aggregate a numeric field in an internal table, the table is as follows
FLD1        FLD2         NUM1       FLD3
123A        B1             10            C1
123A        B1             25            C1
123B        B1             20            C2
123C        B2            10             C3
Note: FLD1, FLD2, FLD3 are of type numeric characters and NUM1 is of type number or integer
I want the result to be as follows
FLD1        FLD2        NUM1        FLD3
123A        B1            35             C1
123B        B1            20             C2
123C        B2            10             C3
i.e. values in field NUM1 should get add up when the values in all other fields are same
I am not able to use _collect_ for this as the fields contain numeric characters.
Regards and Thanks,
Antony

use at new field
      sum

I need to add check whether 21 fields of a internal table are empty or not.

Hello,
I need to add check whether 21 fields of a internal table are empty or not.How can we write a code for the same wand what would be the correct syntax for it.
I tried entering all the fields in the IF loop with AND condition but its giving syntax error.Perhaps this is because the lenght of the IF condition would be more than the allowed one.

Hi,
After the select quiery.
If not itab is initial.
Message 'Table is not empty' type 'I'.
Endif.

First occurence of a value from a field in the internal table.

How to select the first occurence of a value from a field in an internal table ?
I don think , we can use select query .
Any suggestions?
provide syntaxs also .

Hi...
You have to use this code.
DATA : Begin of IT_MARA occurs 0,
 mtart type mara-mtart,
 matnr type mara-matnr,
 meins type mara-meins,
 END OF IT_MARA.
START-of-SELECTION.
SELECT MTART MATNR MEINS FROM MARA INTO TABLE IT_MARA.
END-OF-SELECTION.
LOOP AT IT_MARA.
 AT NEW MTART. "This will trigger for every first/new value of the field
 <<<<WRITE YOUR CODE here>>
 ENDAT.
ENDLOOP.
You can also use.
LOOP AT IT_MARA.
 ON CHANGE OF IT_MARA-TART.
 <<<<WRITE YOUR CODE here>>
 ENDON.
ENDLOOP.
