How to get the Grand Total in Module pool Screen

Hi Frds.
     How to get the Grand Total in Module pool Screen
Example i have 10 different materials
for each matarial has different moving . But in my case matarials is doesnt matter here
10 material Moving Average price to do Frand total and display in one column...
Please Help me out Frds.
Regards,
Kabil

Hi
You need to calculate the total in a module of PAI (or PBO) event:
PROCESS PAI.
   LOOP.....
   ENDLOOP.
MODULE CALCULATE_TOTAL.
MODULE CALCULATE_TOTAL.
    GRAND_TOTAL = 0.
     LOOP AT ITAB,
        GRAND_TOTAL = GRAND_TOTAL + ITAB-PWB.
    ENDLOOP.
ENDMODULE.
In this way the grand total will be calculated as soon as the user presses enter or another command.
You can't insert the calculation in the loop of table control, because this loop runs the visible lines only, so it's better to calculate the total out of those loop,

Displaying MIR4 attachment list TIF image in module pool screen

Hi All,

Please help me on this.
Thanks
Geetha Charan

Hi sai,
Please refer th procedure.
For the select-options you might have defined a selection screen.
Next you can fetch the entire data that you wanted to display in a module pool into an internal table.
you can call the screen you defined for o/p upon the selection.
Then, You define a screen XXXX and a table control in the scree, and in the PAI module of the screen
you write a chain end chain processing in which you can display the contents of your internal table.
OR
if you want the selection also to be in the module pool, then for displaying the O/P you can definr a sub-screen of the initial screen and you can call that sub-screen on selcting, which can be done with a function code.
Hope this helps

Display Continuous Fluctuations in Input Data in Module Pool Screen

Dear All,
We are working on a Weighbridge Interface scenario, where the weighbridge is sending data to a digitizer, which is connected to the COM port of a PC. The objective is to read the data from the digitizer, and display in a Module pool screen. However, there is one more requirement: the weight may fluctuate until it stabilizes, and the fluctuations have to be displayed on screen. For example, the tare weight of a vehicle may be 12.4 TON, but when the vehicle is standing on the weighbridge, the weight may vary from 10.4 to 12.4 TON. The idea is to capture the stable weight, so that any discrepancies can be avoided. In the current IT system implementation, the fluctuations in the weight are displayed. But using ABAP, can these fluctuations be captured? For example, we may design a screen containing a field for capturing the weight, and the weight displayed there automatically refreshes as soon as there is a change in the digitizer reading. Is this possible to achieve? If so, how?
Awaiting answers.
Thanks and Regards,
Sid

Hi Sid,
just a suggestion for the refreshing of an ABAP screen: you can use class CL_GUI_TIMER, but it only handles whole seconds, i.e. 1 second, 2 seconds and so on, but not 0.5 seconds...
An example of an ABAP listing could be the following:
*& Report ZZAVV001
REPORT zzavv001 NO STANDARD PAGE HEADING.
CONSTANTS: c_yes(1) TYPE c VALUE 'X'.
DATA: BEGIN OF t_bseg OCCURS 0.
        INCLUDE STRUCTURE bseg.
DATA: END OF t_bseg.
data: d_num_bkpf type i,
      d_num_bseg type i.
PARAMETERS: interval TYPE i DEFAULT 5. "meaning 5 seconds
*       CLASS lcl_receiver DEFINITION
CLASS lcl_receiver DEFINITION.
PUBLIC SECTION.
    METHODS:
      handle_finished FOR EVENT finished OF cl_gui_timer.
ENDCLASS.                    "lcl_receiver DEFINITION
* Global data

timer      TYPE REF TO cl_gui_timer.
START-OF-SELECTION.
CREATE OBJECT timer.
CREATE OBJECT receiver.
SET HANDLER receiver->handle_finished FOR timer.
timer->interval = interval.
CALL METHOD timer->run.
PERFORM load_data.   "or whatever you have to do to read the weight

    PERFORM carga_datos.
    PERFORM muestra_listado.
    CALL METHOD timer->run.
ENDMETHOD.                    "handle_finished
ENDCLASS.                    "lcl_receiver IMPLEMENTATION

         d_num_bseg.

    into d_num_bkpf
    from bkpf.

    into d_num_bseg
    from bseg.
ENDFORM.                    "load_data

Okay, it's just a tiny code snippet, but I hope it may help you by designing auto-refreshing screens.

Expand/collapse button functionality on module pool screen

Hi ,
I want to design a module pool screen with a expand/collapse button on it.
The desired functionality associated with this button would be something similiar to that available in ME21N screen. When the expand button is clicked it should open up a section of screen that allows the user to enter some parameter. Based on this parameter some selections from DB can be perfomed and then displayed below it.
Any pointers on how to achieve this? Any kind of help would be appreciated.
Regards-
Harmeet Singh.

example for three pushbutton with expand collapse .
First of all define your push button as output field with icon tick in the pushbutton characteristick,
then define this pushbutton in top_include
include <icon>.
data : push_a1 like icons-l4,
 push_a2 like icons-l4,
 push_a3 like icons-l4.
data : a1 ,
 a2,
 a3.
in pai of the screen
suppose i had assign function code a1 ,a2 , a3 for repective pushbutton
module user_command_9002 input.
okcd = ok_code.
clear ok_code.
case okcd.
 when 'A1'.
 if a1 is initial.
 a1 = 'X'.
 else.
 clear a1.
 endif.
 when 'A2'.
 if a2 is initial.
 a2 = 'X'.
 else.
 clear a2.
 endif.
 when 'A3'.
 if a3 is initial.
 a3 = 'X'.
 else.
 clear a3.
 endif.
endcase.
endmodule. " USER_COMMAND_9002 INPUT
define three seprate screen -group for three pushbutton say a1 a2 a3
during pbo you can directly assign name of icon .
if a1 is initial.
 push_a1 = icon_collapse.
else.
 push_a1 = icon_expand.
endif.
if a2 is initial.
 push_a2 = icon_collapse.
else.
 push_a2 = icon_expand.
endif.
if a3 is initial.
 push_a3 = icon_collapse.
else.
 push_a3 = icon_expand.
endif.
loop at screen.
 if screen-group1 = 'A1'.
 if a1 = 'X'.
 screen-invisible = 1.
 screen-input = 0.
 modify screen.
 else.
 screen-active = 1.
 screen-invisible = 0.
 screen-input = 1.
 endif.
 elseif screen-group1 = 'A2'.

Module-pool screen field value under POV event

Hi All,
I have one issue...please suggest me solution for this.
In module-pool program i have one screen(1000) which has one field(hrname_1000).
Under this event:
PROCESS ON VALUE-REQUEST.
FIELD hrname_1000 MODULE hrname_1000.
under this module hename_1000 i have used F4IF_INT_TABLE_VALUE_REQUEST to put a search help for field hrname_1000.
after that i am trying to retrive HR related stuff's based on the field on module-pool i.e i am using hrname_1000 in the where condition.
but problem is that im not getting value for hrname_1000 which im giving in the module-pool screen.
thats y my select query is not working.
Where as im getting values for the hrname_1000 under PBO & PAI.
It will look like below.
PROCESS ON VALUE-REQUEST.
FIELD hrname_1000 MODULE hrname_1000.
(under the above module)
SELECT DISTINCT ename plans FROM pa0001 INTO CORRESPONDING FIELDS OF TABLE itab WHERE stell = '50001026'.
      LOOP AT itab INTO wa WHERE ename = hrname_1000.
      ENDLOOP.
Please suggest
Thanks & regards
Ansumesh

In some of the cases the screen field is present in the screen but not holding the value in the required structure or field.
so here u need to check the option of reading the screen field values explictly..
//once u hit an enter and do the f4 i think the value will be there ...but if u dont hit enter and do an F4 the value cannot hold and i think u r in this case ..
1.Fill the screen field name in the structure dynpread.
DATA: BEGIN OF DYNP_VALUES OCCURS 10.
        INCLUDE STRUCTURE DYNPREAD.
DATA: END   OF DYNP_VALUES.
DYNP_VALUES-FIELDNAME = 'HRNAME_1000'.
APPEND DYNP_VALUES.
* read screen values
CALL FUNCTION 'DYNP_VALUES_READ'
    EXPORTING
      DYNAME     = HELP_REPID "call the repid of ur prog
      DYNUMB     = HELP_DYNNR "pass the screen number
    TABLES
      DYNPFIELDS = DYNP_VALUES
    EXCEPTIONS
      OTHERS     = 1.
now dynp_values hold the field name and field value of the screen .
now
SORT DYNP_VALUES BY FIELDNAME.
    READ TABLE DYNP_VALUES WITH KEY 'HRNAME_1000' BINARY SEARCH.
    IF SY-SUBRC EQ 0.
      HELP_XXXX = DYNP_VALUES-FIELDVALUE. "store the value into a variable
      TRANSLATE HELP_XXXX TO UPPER CASE.
    ENDIF.
Now check the code with the value if its getting populated which once there will make ur select work ..

Date search help in module pool programming in 4.6C version

Hi Experts,
How can i have input help in my module pool screen, I gave the searh help EXT_DATE in the search help parameter of that screen's field parameter.
But its not showing the input help.
I m facing this issue in 4.6C.
Please advise
Thanks
Yogesh Gupta

Hi,
Just to make sure that you are talking about F1 help and not F4 for input of date right?
For F1 help of screen field, please check program for tcode: F150 (Dunning Run), You will find FM: F150_FIELD_SELECTION_HELP used for one field on screen (112).
I guess this might help you.
thanks,

Display Select option in module pool screen

What are the Function modules used to display Select option type fields in a module pool screen?

hi,
You can use the SELECT-OPTIONS statement to place a group of fields on the screen that allows users
to enter complex selections. The selection may be a single value, or any form of interval
Selection ranges are stored in programs using an internal table.
The ABAP statement SELECT-OPTIONS <selname> FOR <field> declares an internal table called
<selname>, containing four fields - SIGN, OPTION, LOW, and HIGH. The fields LOW and HIGH have
the same type as the field <field>.
The SIGN field can take the value 'I' (for inclusive) or 'E' (for exclusive).
The OPTION field can contain relational operators (EQ, NE, LE, LT, GE, GT), pattern operators (CP,NP), and operators that allow you to enter intervals (BT, NB).
SELECTION-SCREEN BEGIN OF BLOCK conn WITH FRAME TITLE text-001.
PARAMETERS pa_car LIKE wa_sflight-carrid OBLIGATORY.
SELECT-OPTIONS: so_car FOR wa_sflight-carrid,
SELECTION-SCREEN END OF BLOCK conn.
Hope this helps, Do reward.

Module pool screen field should default without pressing enter

Hi
I have got a main module pool screen which has a tabstrip with four tabs.
There are 2 fields in the main screen when we select from F4 for the first field then the field 2 should default in case of a condition.
This happens only when i press enter. I want the second field to change as soon as the first field is selected.
How do I trigger the PAI as soon as the field 1 is selected.
eg:                           Field 1 : i/p
                                Field 2 : display
                               Field 3 : i/p
On F4 for field 1 say i select value 'A' then the valu for field 3 should default to value 'B'. Also field 2 should be displayed based on combination of field 1 and field 2. But now it does it only on pressing enter.
How do I solve this problem?Also if i select field 1 value A and dont press enter and go to the subscreen tab then it does not do any thing. It allows to go on the subscreen tab. But actually it should default the field 3 value. It does it only when I press enter.
Also the F4 is from dictionary that is the screen fields are from dictionary. I have not created any F4 for the fields.
Please help me solve this problem
Regards,
mozila

Hi
You can achieve this using List Box only not by Input Field. Since Input field doesn't trigger automatic PAI/PBO
Go through the below thread
populate drop down menu based on entry in another field
or an alternative is--> In PBO use POPUP_GET_VALUES Fm to get the First input field based on that you can enter further values

keep a button called EXIT on the screen
Make the function type of that field as E
in Flow logic write
