Validations and default Values in ALV Grid

All,
I am using "set_table_for_first_display" to display a grid with empty editable rows wherein which users can enter data and process certain transactions.
My requirement is to know if we can provide drop-downs and default values in this grid. for ex. if user want to insert a row, that row should automatically have some default values like company code, sales org etc.
Also, if there is an error while validating the data, I should be able to set the focus on that field while displaying the error message. I was able to display error message but could not set the focus on the field that need to be corrected.
Your earlier response is much appreciated.
Regards
Kasi

How to change sub total value in ALV Grid.

Hi All,
Can u please explain how to change SUBTOTAL Value in ALV Grid display based on another field value.
EX; F1 subtotal is initial then we have to modify the F2 sub total to 9999.9.
Thanks
Radha.

Hi Radha,
I doubt if that can be changed....because the event that i was referring to in my previous post works with ALV List display...But in any case you can try that.....
There is an event in SLIS....(As i told you, i dont remember the name and currently i dont have access to SAP system, so i am not able to verify and let you know that event name).....
Other thatn TOP and END of PAGE events, there is an event for sub-total text......i think it would start with "SUBTOTAL"...
you need to use that event in your events table and pass it to ALV Grid display.
Then create a sub-routine with that name (As you do for TOP-OF-PAGE event)....and in this event you can change the values in runtime (PROVIDED, this event gets triggered for ALV GRID).....
If this does not work, i think calculating sub-totals while you build the internal table would be a better option....(If you have time constraint....else you can do some more research on the same)........
Best Regards,
Ram.

Medium, min, and max values on ALV

Hi friends ! How are are you ? Fine ?
How can i calc medium, min, and max values on ALV ?
Thanks !

Hi Fabrício
I think you set fieldcatalog at runtime dynamically to arrange dynamic columns. So, while you are setting it just set proper values to the attribute "do_sum" for relevant fields.
For more information how to set fieldcatalog dynamically, you can refer to the tutorial "An Easy Reference for ALV Grid Control".

Pack and Integer type in ALV grid

Hello,
Can anyone give a small example of how to display fields of type I and P in an ALV grid. Using the alv grid FM and manually filling the fieldcatalog.
Thanks for your help.

Hi Moussa Khelifi ,
u can manually fill fieldcatalog like this..
form manual_filling_fieldcatalog.
X_FIELDCAT-FIELDNAME = 'ATWRT'.
X_FIELDCAT-TABNAME   = 'TB_FINAL'.
X_FIELDCAT-SELTEXT_L = 'Source of Supply'(001).
X_FIELDCAT-DDICTXT   = L_DDICTXT.
X_FIELDCAT-FIELDNAME = 'MATNR'.
X_FIELDCAT-TABNAME   = 'TB_FINAL'.
X_FIELDCAT-SELTEXT_L = 'MATERIAL'(002).
X_FIELDCAT-DDICTXT   = L_DDICTXT.
APPEND X_FIELDCAT TO TB_FIELDCAT .
endform.
u can directly pass the table to 'REUSE_ALV_GRID_DISPLAY'
regardless of type p or i fields in it.

Default values in ALV

When i add a new row in ALV in webdynpro, i need some columns to have some default values. I am using the standard functionality of ALV in webdynpro to append rows (that is by setting the set_editable property to abap_true). Could someone tell how i can achieve this.
regards,
Priyank

Hi Juan,
thanks for the reply,
What i need is slightly different. When i append new rows, the new row should have default values based on the last row in the grid. For example, there are start dates and end dates in the grid, for the new row, the start date should be one day after the end date in the preceding row. Could you tell me how i can achieve this.

Priyank

Urgent : Insert , save and Delete in the alv grid

Hi Experts,
I am having a alv grid and displaying data by fetching from backend.
i added a toolbar buttons "Insert " "Save" and "Delete".
when i click on "Insert " button the first row of the table should be empty with input fields. i want to insert data and when i click on "save" button it should update at backend.kindly let me know how to insert empty row at starting of alv grid and also how to save and delete records..
thanks in advance.

Hi Bharath,
Go through this hope u can understand.
SEL_MODE. Selection mode, determines how rows can be selected. Can have the following values:
A Multiple columns, multiple rows with selection buttons.
B Simple selection, listbox, Single row/column
C Multiple rows without buttons
D Multiple rows with buttons and select all ICON
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 similar 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 from the table. In the examples below the grid table is named gi_sflight.
Data declaration:
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.

Text Box/Area and default value

Is it possible to display a Text Box (or Text Area) in a Form page assigned a default value and prevent the user to change it? I need to register the actual user submitting the form. I have done this in WebDB22 Text Box and #user function but in Portal 3.0.6.6.5 it seems to be impossible to prevent the user to change the text value. Deselecting Validation Options, Updatable does not seems to help. Why?

The equivalent of Webdb #user function in portal is #portal30.wwctx_api.get_user.
If you specify this as a default value for a field it will be the same as #user. Also, "inseratble" and "updatable" checkboxes control the presence of a column in INSERT and UPDATE statements, so unchecking any of those checkboxes will remove the column from a respective statement.
Thanks,
Dmitry

Get checkbox values from alv grid

Hi,
I'm using the function REUSE_ALV_GRID_DISPLAY and I'm showing a table with a field like a checkbox.
In USER_COMMAND FORM to get selected values do as follow:
    CALL METHOD REF_GRID->CHECK_CHANGED_DATA.
And then:
loop at i_pos (my table) with checkbox eq 'X'.
endloop.
The first time I execute the ALV every thing is OK but if I do any action (I use the function 'BAPI_GOODSMVT_CREATE' ...), I refresh the data and I raise the alv again. In USER COMMAND FORM the code is the same and I can not get checkbox values.
Can someone help me please?

Update values in AlV grid display after entering value

Hi,
     I have an issue in ALV grid display.
    Let me explain.
    i have 8 fields to display in which one is editiable.
   Fields are: date
                   material,
                   material Description,
                   Opening Stock,
                   Closing stock- ( this field is editiable)
                   Closing stock,
                   Received Stock,
                   Actual production.
Actual production = Closing stock + removal stock
                             - receipt stock - opening stock.
when i change the value of closing stock and press enter, actual production should get update, the new values should display.
Thany you in advance.

How to capture changed value in ALV Grid

Hi Guys,
I have an ALV grid report where I have 'Edit On' for one of the quantity fields in the report. How do I capture the new (changed) value in the suboutine for user command when user changes the value in the report and clicks on a button ?
Points assured for helpful replies.

FORM USER_COMMAND USING P_UCOMM LIKE SY-UCOMM...........
Data ref1 type ref to cl_gui_alv_grid.
CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
IMPORTING
E_GRID = ref1.
call method ref1->check_changed_data
ENDFORM.
Also chk the blog
