ALV subtotals using methods

Hi
Please provide me sample code for subtotals using methods.
The code is
DATA: ls_sort TYPE lvc_s_sort.
ls_sort-spos = '1' .
ls_sort-fieldname = 'BWART'.
ls_sort-up = 'X'.
ls_sort-subtot = 'X'.
*ls_sort-group = 'UL'.
APPEND ls_sort TO p_gt_sort.
endform
but it is not working
Please help me

Possible to have vertical scroll bar for a cell in ALV Grid (using methods)

Hi All,
I have a field with length 100 characters on a ALV Grid (using methods)..User doesn't want to scroll all the 100 characters horizontally to see the whole text rather he wants to have a vertical scroll bar for the cell so that he can scroll vertically.
Is it possible to have split the cell text into lines and have a vertical scroll bar for a cell in ALV Grid?
Regards
Jaker.

Thanks for the suggestion Balu.I tried this , but while scrolling,headers also getting scrolled.
Becoz of this , if i scroll down to the last row,headers are getting hidden.
Headers should always be static.only the data should scroll.
Since h:datatable is being rendered as one table , i can div tag for this table alone.
If i have seperate datatable for headers alone i can do this .But i should not use two datatables.

ALV grid using methods: how to get modified cells

Hi all,
IAM USING alv grid using methods,
i have few fields as editable
if the user edits any of those fields how can i know which cell is modified and what is the new value.
i tried to use method get_modified_cells
but iam getting a msg saying protected method and u can not use.
please advise.
thanks

Jafar,
You need to Take the Help of DATA_CHANGED event, when ever there is a change in the Grid, it will trigger, here you can capture the Cells which are modified.
in your PAI call the method check changed data
CL_GUI_ALV_GRID-->CHECK_CHANGED_DATA
You need to set the handler for datachanged.
set the handler for this, and register the event modified or enter.
**Handler to Check the Data Change
    HANDLE_DATA_CHANGED FOR EVENT DATA_CHANGED
                         OF CL_GUI_ALV_GRID

ALV Grid Using Methods-handle_top_of_page

riends please explain how to resolve the below issue.
I am working on ALV Grid using methods & trying to display
page heading using handle_top_of_page event.
I have defined & implemented the above method and in the implementation I have
given a write statement, which has to be displayed on the top of page.
I have also set the handler for top of page.
The program does not have any errors, but top of page event is not triggered, what might be the problem.

How to make a field manadatory within ALV Grid using methods and classes

Hi,
I am using ALV Grid using set_table_for_first_display
inside my dialog programming. I have a field called project number inside my grid which has to be made as mandatory field.
I have defined a method called catch_data_changed inside my class lcl_event_receiver. This method captures the changes made to one of the fields inside my ALV grid and displays all the default values of the other fields from the grid.
Now, i have to make project number which is one of my fields inside my ALV grid as mandatory. At the field catalog level i did not find any such option for making a field as required field.
Is there any other way, i can accomplish this within the ALV grid?

from my understanding from ur question, i understood that u want the editable field inside alvgrid to be mandatory.
i dont know anthing in fieldcat, but u can try the following logic.
FORM DATA_CHANGED USING P_ER_DATA_CHANGED TYPE REF TO
CL_ALV_CHANGED_DATA_PROTOCOL .
DATA: L_VALUE TYPE LVC_VALUE,
    ls_mod_cell type lvc_s_modi.
READ TABLE P_ER_DATA_CHANGED->MT_MOD_CELLS INTO LS_MOD_CELL.
if sy-subrc = 0.
    CALL METHOD P_ER_DATA_CHANGED->GET_CELL_VALUE
      EXPORTING
        I_ROW_ID    = LS_MOD_CELL-row_id
        I_FIELDNAME = LS_MOD_CELL-fieldname
      IMPORTING
        E_VALUE     = L_VALUE.
IF LS_MOD_CELL-FIELDNAME <> 'fieldname what u want'
MESSAGE 'ENTER VALUE INTO (fieldname u want) ' TYPE 'I'.
ENDIF.
ELSE.

ALV Reports using Class Methods

Hi Experts,
How can we generate ALV report using class and in that How can we define SLIS_EVENTS.
Can I provide all the that functionality the way I used to by calling FM
SLIS_ALV_REUSE_LIST_DISPLAY ?
- Like Header comment, event, data grouping , sort etc.
You may please send any url or document or any example.
Thanks in advance.

Hi,
The ALV object Grid methods allow the same functionality as ALV grid report function modules but are displayed within
a screen (dialog program). SAP has provided a suit of programs which demonstrate how to For examples see standard SAP
programs as detailed below:
BCALV_EDIT_01 This report illustrates the simplest case of using an editable/noneditable ALV Grid Control.
BCALV_EDIT_02 This report illustrates how to set chosen cells of an ALV Grid Control editable.
BCALV_EDIT_03 In this example the user may change values of fields SEATSOCC (occupied seats) and/or PLANETYPE.
The report checks the input value(s) semantically and provides protocol messages in case of error
BCALV_EDIT_04 This report illustrates how to add and remove lines to a table using the ALV Grid Control and how to
implement the saving of the new data.
BCALV_EDIT_05 This example shows how to use checkboxes within an ALV Grid Control. You learn:
(1) how to define a column for editable checkboxes for an attribute of your list
(2) how to evaluate the checked checkboxes
(3) how to switch between editable and non-editable checkboxes
BCALV_EDIT_06 This example shows how to define a dropdown listbox for all cells of one column in an editable ALV
Grid Control.
BCALV_EDIT_07 This example shows how to define dropdown listboxes for particular cells of your output table.
BCALV_EDIT_08 This report implements an ALV Grid Control with an application specific F4 help. The following aspects
are dealt with:
(1) how to replace the standard f4 help
(2) how to pass the selected value to the ALV Grid Control
(3) how to build an f4 help, whose value range depend on a value of another cell.

Problem with focus with an ALV grid using object methods

Hi, i have an editable ALV and there is something wrong that we haven't been able to solve it yet, hope you can understand my explanation
Supose a grid 2 x 5
cell 1 - cell 2 - Cell 3 - Cell 4 - Cell 5
001      John      Doe
So when a press tab or enter to the any cell diferent from cell 1 the focus get back to the cell 1, and i have to tab ( in this example) 3 times to fill cell 4, and then 4 times to fill cell 5
Any ideas???

Hi,
Use method :SET_CURRENT_CELL_VIA_ID of grid to set the cursor position in a cell.
Ex:
CALL METHOD O_GRID->SET_CURRENT_CELL_VIA_ID
      EXPORTING
        IS_ROW_ID    = V_ROW
        IS_COLUMN_ID = V_COLUMN
        IS_ROW_NO    = V_ROW_NUM.
use methods : get_current_cell_row_id, get_current_cell
to get the required parameters for SET_CURRENT_CELL_VIA_ID.

Call ALV gid inside Method using class

Hi all,
I have created one method in my ZClass, in that i need to write code for display a pop-up(ALV) that should contain the internal table records. Also if i double click a cell in that popup then a transaction(say ztest) should be called..
How to do this inside the method?
Thanks,
Ranjith C.

Hi,
You can call screen in you class and assign the custum container to the screen, using cl_gui_alv_grid class assing created object to container and create fields catlog and internal table with data to display in alv. call the method set_table_for_first_display to display data.
You can also used the method get_selected_rows to read current selected line data can use call transaction.
For more details you can used the pakage slis there are may program are avaible to resolve your problem.

End of page in ALV using METHODS

Hi Folks,
I have to display End of Page in an list which is using
CALL METHOD grid1->set_table_for_first_display for display.Is there any method in the same way so that I can totals at the end of page in that list.
For you info I am not using any of the REUSE_ALV_...... function modules in the program.So kindly let me know how to get it using methods.
Thanks,
K.Kiran.

Hello Pratuysh,
Thanks for the answer
I know that report,but that doesn't help me.
Any other way
Thanks

Sub total in ALV GRID using oops concept

Hi,
If Plant (VBAP-WERKS) is not the same for all items on a Sales Order (VBAK-VBELN is the same for al items) then create a separate line on the report for each different plant specified in the line items. Copy all fields from the original order line except for plant and Net Value. Net Value should be the total of item Net Values for all items with the same plant in the order.
Example:
Data:
Order----                     Item-             Plant-                                     Net Value---
123----          010-               3467-                      100.00---
123----          020-               7865-                      50.00---
123----          030-               3467-                     80.50---
Report:
Order-                     Plant-                  Net Value---
123-          3467-                  180.50---
123-          7865-                   50.00----
I need to dispaly the Report format in ALV Grid using oops concept...
no need of calling any function modules.
Regards,
Nithya

Hi
Here is example code
This is the method to be called:
get_subtotals
Use
Returns the current subtotals of the ALV Grid Control. Having created totals for at least one column, users can calculate at most nine subtotals. The list is sorted by the values of one or several columns (called the subtotals column). If a value is changed in the subtotals column, the subtotal is displayed (this is also referred to as control level change).
Integration
Before you access the subtotals value, you use the method get_sort_criteria to get the sort table . One row of this table describes properties of a column in the output table.
If the field SUBTOT is set for a column in this table, the column is a subtotals column.
The field SPOS then indicates at which level (see below) the subtotal has been calculated.
The field FIELDNAME contains the name of the subtotals column in the output table.
Based on this information, you specifically access the values of the tables passed (using reference variables COLLECT01 to COLLECT09).
Features
CALL METHOD <ref. var. to CL_GUI_ALV_GRID>->get_subtotals
IMPORTING
EP_COLLECT00 = <reference variable of type REF TO DATA>
EP_COLLECT01 = <reference variable of type REF TO DATA>
EP_COLLECT02 = <reference variable of type REF TO DATA>
EP_COLLECT03 = <reference variable of type REF TO DATA>
EP_COLLECT04 = <reference variable of type REF TO DATA>
EP_COLLECT05 = <reference variable of type REF TO DATA>
EP_COLLECT06 = <reference variable of type REF TO DATA>
EP_COLLECT07 = <reference variable of type REF TO DATA>
EP_COLLECT08 = <reference variable of type REF TO DATA>
EP_COLLECT09 = <reference variable of type REF TO DATA>
ET_GROUPLEVELS = <ínternal table of type LVC_T_GRPL>.
In order to access the values of EP_COLLECT00 to EP_COLLECT09, you use ASSIGN to dereference the relevant reference variable in a field symbol of your output table type (see below).
Parameters
Meaning
EP_COLLECT00
Points to the totals line. Since there is only one totals line which, in addition, has a unique totalling area, no further information is available for this table in table ET_GROUPLEVELS.
get_subtotals
EP_COLLECT01 to EP_COLLECT09
Point to the subtotals line. For each subtotals level, there is one reference variable. Each of these variables points to an internal table that has the type of the output table. EP_COLLECT01 points to the subtotal at the hightest level, while EP_COLLECT02 points to the subtotal at the second highest level, and so on. The levels are derived from the sort priority (field SPOS in the sort table ). The column by which the data was sorted first, is the highest subtotals level.
ET_GROUPLEVELS
Manages all indexes for the individual control levels. The fields of the table have the following meaning:
INDEX_FROM, INDEX_TO: Rows of the output table for which the subtotal was created
LEVEL: Subtotals level (see above)
COUNTER: Number of rows for which the subtotal was created
COMPRESS: For this subtotals line, the user has hidden the associated rows.
COLLECT: Indicates the subtotals table (01-09) in which the values are stored
For an overview, see Methods of Class CL_GUI_ALV_GRID

End of Page event in ALV report using SALV class[cl_salv_hierseq_table]

Hi ,
have been working on a ALV report using the class SALV cl_salv_hierseq_table
I am facing few issues pertaining to two things:
1. Displaying some subtotal text along with the subtotals.
Example refer the standard demo example: SALV_DEMO_HIERSEQ_FORM_EVENTS
Now instead of A 17 and A26 I would like to show text like Subtotal for the Carrid.for subtotals and grand totals
Like Subtotal for A 17 is : XXXXXXX
GrandTotal is : YYYYYY
2. We have a page break and a new page for every purchasing group as in the standard example SALV_DEMO_HIERSEQ_FORM_EVENTS for CARRID.
I need to display some variable values as number of documents ,total number of records etc at the end of each CARRID group before a new page starts for the next CARRID.Please note i do not want it on every page.it should only be diaplyed at the end of page whose next page would be for next CARRID.[basically at end of every carrid]Example:after displaying all details for AA need to display the number of records for that carrid at the end of the page[as page break is based on CARRID]/
Thanks
Jyotsna

at end of page event, for CL_SALV_EVENTS_HIERSEQ, has some useful parameters allowing to know where you are at the time of event
parameter VALUE is of type CL_SALV_FORM which contains public attribute IF_SALV_FORM~ACCDESCRIPTION; you can slo get contents of it
about text of total/subtotal, this is normally set in the layout

ALV report using the field catalog

which is the quickest way to generate an ALV report using the field catalog merge. without needing to build the field catalog manually .
is it easier to create a structure and passe it in the field catalog merge . if yes can i have an example plzzzz

hI
Supports the creation of the field catalog for the ALV function modules
based either on a structure or table defined in the ABAP Data
Dictionary, or a program-internal table.
The program-internal table must either be in a TOP Include or its
Include must be specified explicitly in the interface.
The variant based on a program-internal table should only be used for
rapid prototyping since the following restrictions apply:
o Performance is affected since the code of the table definition must
always be read and interpreted at runtime.
o Dictionary references are only considered if the keywords LIKE or
INCLUDE STRUCTURE (not TYPE) are used.
If the field catalog contains more than 90 fields, the first 90 fields
are output in the list by default whereas the remaining fields are only
available in the field selection.
If the field catalog is passed with values, they are merged with the
'automatically' found information.
Below is an example ABAP program which will populate a simple internal table(it_ekpo) with data and
display it using the basic ALV grid functionality(including column total). The example details the main
sections of coding required to implement the ALV grid functionality:
                         Data declaration
                         Data retrieval
                         Build fieldcatalog
                         Build layout setup
*& Report ZDEMO_ALVGRID                                               *
*& Example of a simple ALV Grid Report                                 *
*& The basic requirement for this demo is to display a number of       *
*& fields from the EKKO table.                                         *
