Struggling with f4 handling in ALV grid - Minisap 46D

Hi to all,
I got an abap problem developing with my Minisap 46D,
and i can't realy struggle out for a solution,
Issue concern using of self defined F4 in ALV ( created via objects),
Each program (standard program as in eg.BCALV_GRID_EDIT )
given by SAP to show use of ALV self definded F4 doesn't wark at all this option,
and when i click on the cell in order to show F4 set of values, program brake down in ABAP error,
Always the same happen with my z programs when they calls method written to manage F4,
following existing examplaes i think i put instructions in the right place and in proper way:
I mean defining implementing and registering onf4 event,
Further i see that standard programs with f4 dumping on my minisap are working proper on the normal SAP at work place,
Does this depend on some Minisap strange bugs in standard ALV class? What can i do?
I would be grateful to anyone who help me solving this SAP mistery,
So I got:
Error analysis (and syntesys of the short dump )
ABAP runtime errors    CALL_METHOD_CONFLICT_TYPE
The call to method "ON_F4" is incorrect
The system tried to pass field "%_DUMMY$$" to the formal parameter " ".
"CALL_METHOD_CONFLICT_TYPE"

     and set handling event but is the usual, as
     indicated in standard procedure,

I would recommend above all else simply upgrading:

Urgent checkboxes handling in alv grid

helo all .i need to handle checkboxes in alv grid.
i did like
case u_comm.
when 'save'.
perform save.
endcase.
in the form.
form save.
loop at it_mara into it_mara1 where chk = 'X'
and moving the contents to it_mara1.
but after doing it is not looping when i have seen in debug .
plz help me
i need to have those selected values and move a head.

Hi rakhee,
First add a single charecter field into the internal table you want to display in the ALV.Then set the field cataloge and set the value for Checkbox as 'X'.it wil display the field as a check box.when you check the check box it will update the internal table also.
please check the below code.
TYPE-POOLS : slis.
TYPES : BEGIN OF st_mara.
TYPES : matnr TYPE mara-matnr.
TYPES : a,
END OF st_mara.
DATA : it_fieldcat TYPE slis_t_fieldcat_alv,
       wa_fieldcat LIKE LINE OF it_fieldcat.
DATA : it_mara TYPE TABLE OF st_mara.
SELECT * FROM mara
         INTO CORRESPONDING FIELDS OF TABLE it_mara UP TO 1 ROWS.
wa_fieldcat-col_pos = 1.
wa_fieldcat-fieldname = 'A'.
wa_fieldcat-checkbox = 'X'.
wa_fieldcat-edit = 'X'.
APPEND wa_fieldcat TO it_fieldcat.
CLEAR wa_fieldcat.
wa_fieldcat-col_pos = 2.
wa_fieldcat-fieldname = 'MATNR'.
APPEND wa_fieldcat TO it_fieldcat.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
    it_fieldcat = it_fieldcat
TABLES
    t_outtab    = it_mara.
BREAK-POINT.
if you are using controls just call the method
CALL METHOD grid1->check_changed_data.
grid1 is the instance of the ALV grid.
when the method is called you will get the internal table with the field marked as 'X'.

Each ALV Grid display a table....
Each toolbar of the grid has a print button.....
Here i have 2 questions...
i) when a print button of a grid is pressed..how can i know the grid of which the print button is pressed...i.e. if grid one print button is pressed..then how can i know it is triggered from Grid one and likewise for grid 2 and grid 3.
Im using same method for the event user_command for the three grids.......
ii) WHen layout is changed for a particular ALV grid...i.e. if some columns are made hidden...then when print button is pressed..Then i need to print only the columns of changed layout.............
How can i know the columns of the changed layout..........

1 - In local class definition, use the [SENDER|http://help.sap.com/saphelp_nw04s/helpdata/en/71/a8a77955bc11d194aa0000e8353423/frameset.htm] parameter of the event you manage.
CLASS lcl_event_receiver DEFINITION.
PUBLIC SECTION.
 METHODS:
 handle_double_click
 FOR EVENT double_click OF cl_gui_alv_grid
 IMPORTING e_row e_column sender.
PRIVATE SECTION.
ENDCLASS.
Then in the implemented method check the value, or use the object sender like any alv grid object.
CLASS lcl_event_receiver IMPLEMENTATION.
METHOD handle_double_click.
 CASE sender.
 WHEN grid1.
(Doc: [Event Handling|http://help.sap.com/saphelp_sm32/helpdata/EN/9b/d080b49fc111d2bd68080009b4534c/frameset.htm])
2-use the method [GET_FRONTEND_FIELDCATALOG|https://www.sdn.sap.com/irj/scn/advancedsearch?query=get_frontend_fieldcatalog&cat=sdn_all] of CL_GUI_ALV_GRID to get the curent layout.

Problem with check box in ALV Grid Display

I am Displaying Material Master Data in ALV Grid Display with Check Box for each record and if i checked check box then i am processing Update operation in Database, my question is after perform update operation check box should be clear.
Kindly help me!!!!

Hello Raj
Given the fact that you do not tell us the most important piece of information (namely whether you are using OO-based ALV or not) I assume you are using fm-based ALV lists.
In this case you probably have defined a USER_COMMAND routine as described in the documentation of the fm.
FORM user_command USING r_ucomm LIKE sy-ucomm
 rs_selfield TYPE slis_selfield.
* define local data
DATA: ls_outtab LIKE LINE OF gt_outtab,
 ld_idx TYPE i.
LOOP AT gt_outtab INTO ls_outtab
 WHERE ( chkbox = 'X' ).
 ld_idx = syst-tabix.
 " Call your update function / method / perform
 ls_outtab-chkbox = space.
 MODIFY gt_outtab FROM ls_outtab INDEX ld_Idx
 TRANSPORTING chkbox.
ENDLOOP.
" And now trigger refresh of the ALV display:
rs_selfield-refresh = 'X'. " <<< !!!
ENDFORM.

Add column with preq number to ALV grid in me53n

hi all,
i am trying to add column with preq number (BANFN) to ALV with preq items in ME53N. it is not available in column set, when trying to add by "change layout" button - i dont understand why, when the strcucture MEREQ3211GRID contains it :-(
i also tried to add new field ZZBANFN into the structure CI_EBANMEM and after that, i could add the new field to ALV through change layout, but it was empty of course. so i implemented EXIT_SAPLMEREQ_001 from MEREQ001, but ZZBANFN is still empty, because this exit is not called when opening ME53N, but when clicking on tab "customer data" in preq item detail.
how to solve this? is there any exit that is called before displaying the ALV grid?

Here is some more detail. I included my code from the Enhancement.
ENHANCEMENT-POINT MM06EFPO_POT_AUFBAUEN_02 SPOTS ES_MM06EFPO_POT_AUFBAUEN INCLUDE BOUND.
   ENHANCEMENT 1 Z_MM06EFPO_POT_AUFBAUEN_1.    "active version
SELECT SINGLE zz_old_material FROM mara
    INTO pot-zz_old_material
    WHERE matnr = pot-matnr.
ENDENHANCEMENT.
You will also need to change the layout in Item Overview to bring your field in.

Problem with Excel button in ALV Grid...URGENT

Hi All,
I have developed a report in ALV Grid. As we all know that by default we get few buttons in ALV Grid, like summation, sorting download, etc.. In that we have one excel button. When i click that excel button the output of the report should give the output in excel sheet. But this is not working.
The report is running fine except the excel button.
Do anyone of u have any idea how to do that?
Its very urgent...
Regards,
Parvez.

Go through the code and Execute it on your system, I think this will do for you.
In this code I used 3 radio buttons in my selection screen:
If u selects the first radio button your out put shows into to the Excel sheet.
If u selects the second radio button your out put shows the in the Editor screen.
If u clicks the third radio button your output shows into the Excel as well as in the Editor.

Decimal with initial value in ALV GRID

I am using ALV GRID and one of the fields displays quantity. When I have values in this field, it is displayed correctly, but when I do not have value, instead of displaying "0.00000" displays an empty space. How do I display "0.00000"?
Used following code:
    wa_fieldcat-tabname       = lv_tabname         .
     wa_fieldcat-fieldname     = 'QUANTITY'         .
     wa_fieldcat-ref_fieldname = 'QUANTITY'         .
     wa_fieldcat-ref_tabname   = lv_tabname         .
     wa_fieldcat-just          = 'R'                .
     wa_fieldcat-col_pos       = i                  .
     wa_fieldcat-seltext_l     = text-011           .
     wa_fieldcat-seltext_m     = text-011           .
     wa_fieldcat-seltext_s     = text-011           .
     wa_fieldcat-outputlen     = 20                 .
     wa_fieldcat-qfieldname    = 'ZMENGE_D'.
     APPEND wa_fieldcat TO t_fieldcat.
ZMENGE_D' is data element with QUAN data type lenght 5, decimal plaes 5. This data element is used in QUANTITY ref_fieldname.

Hi Zhang,
     I Set wa_fieldcat-qfieldname and display "0.00000", However, all other fields were plain when you have values. In the second row, for example, a value of "8.000,00000" is displayed with "8000.00000". I need the initial valir appears with "0,00000" and the values filled in the format "8.000,00000".

Problem with print preview in alv grid

Hello all,
I have to display base unit of measure(meins) in alv grid output. i am using a conversion routine to convert it from ST TO PC before display.After executing the report i am getting the correct data. the problem is when i select the print preview
alv list is displayed. in that the unit of measure pc is not displayed, it is comming as '*******. what i came to know is the same conversion routine is triggered in the standard program for the display. so it canot convert that.
so please help me out in solving this.
Thanks in advance,
Sarat

hi sarath,
this is an example code try using the statement before displaying, i think it works.
*example cdoe.
LOOP AT i_grp1 INTO wa_grp1.
AT NEW tknum.
READ TABLE i_grp1 intto wa_grp1 index sy-tabix.
SUM.
MOVE-CORRESPONDING wa_grp1 TO wa_grp2.
APPEND wa_grp2 TO i_grp2.
ENDAT.

Create unique handle for ALV grid layout

Hi,
in some generic classes we display internal tables in a grid. We want to activate the save&maintain layouts feature by passing the DISVARIANT structure, Here wen have to give Report and handle. As we display some more tables using the same method, we must set a unique handle so that saved ALV layouts do not get merged /confused. As we do not have a table name at this point, my idea is to create a hash key based on the fields in the field catalog (field catalog is only distinguishable object here).
I need an algorithm to create the 4-character handle as a hash value based on the (concatenated) field names in field catalog.
Or a better idea to create unique handles in the generic ALV calls in one program.
Please: Serious answers only.
Regards,
Clemens

How to fill field with test data in alv grid display

hi all,
i m adding field TEXT to the structure for displaying grid.
i m modifying program like this
DATA: ALV_OUTPUT LIKE HRPDV_EXPIRED_Q OCCURS 0 WITH HEADER LINE.
TYPES : BEGIN OF FS_OUTPUT .
 TEXT(20) TYPE C.
 INCLUDE STRUCTURE HRPDV_EXPIRED_Q.
TYPES TEXT(20) TYPE C.
TYPES END OF FS_OUTPUT.
DATA: fs_output like table of alv_output.
CLEAR WA_FIELDCAT.
WA_FIELDCAT-FIELDNAME = 'TEXT'.
WA_FIELDCAT-seltext_l = 'Abteilungs Struktur'.
wa_fieldcat-tabname = 'ALV_OUTPUT'.
WA_FIELDCAT-COL_POS = '13'.
APPEND WA_FIELDCAT TO P_GT_FIELDCAT.
this is what i have write for diapalying field. but my question is how to fill test data with field TEXT.I m writing like this but not executed in the aboove grid dispaly statement.
loop at alv_output.
*alv_output-text(20) = 'abcdefgh'.
*modify alv_output.
*endloop.
plz tell me how to fill test data

hI..,
Your table declaration has to be like this..
TYPES : BEGIN OF FS_OUTPUT .
INCLUDE STRUCTURE HRPDV_EXPIRED_Q.
TYPES TEXT(20) TYPE C.
TYPES END OF FS_OUTPUT.
DATA: ALV_OUTPUT LIKE standard table of fs_output initial size 0.
loop at alv_output into fs_output.
fs_output-text(20) = 'abcdefgh'.
modify alv_output index sy-tabix from fs_output transporting text.
endloop.
Now give this table alv_output to the GRID_DISPLAY function module..
you will get the required output !!
Plz do remember to close the thread when ur problem is solved !!
reward all helpful answers !!

sai ramesh

Double click on list field in ALV grid control

Hello all,
I developed a report with a ALV grid control. I would like to move some functionality from marking a line and pressing a button in the status line to double clicking a specific field in the output list and execute a command there (i.e. double click on PO number and go to PO display TAC then). Can anybody provide some example coding for that?
Thanks so much for your help!
