Call selection screen from DYNPRO

I created a report with std selection screen 1000...
From this selection screen we reach Dynrpro 9000 with a table control etc etc
Once a line has been selected and the user click on a specific button a selection screen is called...
SELECTION-SCREEN BEGIN OF SCREEN 9005.
SELECTION-SCREEN: FUNCTION KEY 1.
SELECT-OPTIONS : SO_PERSA FOR L_PERSA,
                 SO_BTRTL FOR L_BTRTL,
                 SO_PERSG FOR L_PERSG,
                 SO_PERSK FOR L_PERSK.
SELECTION-SCREEN END OF SCREEN 9005.
Unfortunatly when I try to fill in the range but pressing mutliple line button nothing happens...
Do you have any clue to solve this issue ?

what is the purpose of defining a func which is triggered for eac selection field ??
what is the function of it that you need it and don't want the user to use the available searchoptions ??
kind regards

Back on a CALL SELECTION-SCREEN from an ALV

Hi all,
I have created a program with a normal selection-screen (1000).
According to the selected values, when I press "Execute" I go to a next selection-screen (2000) with instruction CALL SELECTION-SCREEN 2000.
Then I display an ALV.
When I press the back button, I want to go back to screen 2000, but actually I go directly to screen 1000.
PARAMETERS : p_choic1 RADIOBUTTON GROUP cho DEFAULT 'X'.
PARAMETERS : p_choic2 RADIOBUTTON GROUP cho.
SELECTION-SCREEN BEGIN OF SCREEN 2000.
PARAMETERS : p_table TYPE char10.
SELECTION-SCREEN END OF SCREEN 2000.
START-OF-SELECTION.
IF NOT p_choic1 IS INITIAL.
    CALL SELECTION-SCREEN 2000.
    PERFORM alv_process.
ENDIF.
Have you got any idea of what I can do to return to screen 2000 from the ALV after pressing Back button ?
Thanks.

Hi,
Follow below sample code...
SELECTION-SCREEN BEGIN OF SCREEN 2000.
PARAMETERS p_mat TYPE matnr.
PARAMETERS p_enam TYPE ernam.

set PF-STATUS 'STATUS'.
WRITE:/ p_mat,
          p_enam.
AT USER-COMMAND.
CASE SY-UCOMM.
WHEN 'S2000'.
      CALL SELECTION-SCREEN 2000.
WHEN 'EXIT'.
      EXIT.
ENDCASE.

Calling selection screen from another selecton screen.

Hi guys,
I want to call default selection screen of one program from default selection screen of another program.
Is that possible . would appreciate some helpful answers.
Thanks,
Venkat.

it is possiable.
1.submit
2. call transcation t_code.
Syntax
SUBMIT <prog>.
For more information about the SUBMIT statement, see Calling Executable Programs (Reports)
Assume the following simple report:
REPORT ZDYN3.
WRITE / 'Dynamic Program!'.
The following executable program (report) starts, modifies, and restarts ZDYN3:
REPORT ZMASTER1.
DATA CODE(72) OCCURS 10.
DATA LIN TYPE I.
READ REPORT 'ZDYN3' INTO CODE.
SUBMIT ZDYN3 AND RETURN.
DESCRIBE TABLE CODE LINES LIN.
MODIFY CODE INDEX LIN FROM
'WRITE / ''Dynamic Program Changed!''.'.
INSERT REPORT 'ZDYN3' FROM CODE.
SUBMIT ZDYN3.
The output of this program is displayed on two subsequent output screens. The first screen displays:
Dynamic Program!
The second screen displays:
Dynamic Program Changed !
When you use the SUBMIT statement, all modifications made to a program during runtime take immediate effect before they are submitted. In the above example, ZDYN3 is submitted from ZMASTER1 first in its original and then in its modified form, generating different results.
This is not the case if you change the codes of include programs or subroutines dynamically.
Assume the following include program:
INCLUDE ZINCLUD1.
WRITE / 'Original INCLUDE program!'.
and an executable program (report) for modifying and including it:
REPORT ZMASTER2.
DATA CODE(72) OCCURS 10.
DATA LIN TYPE I.
READ REPORT 'ZINCLUD1' INTO CODE.
DESCRIBE TABLE CODE LINES LIN.
MODIFY CODE INDEX LIN FROM
'WRITE / ''Changed INCLUDE program!''.'.
INSERT REPORT 'ZINCLUD1' FROM CODE.
INCLUDE ZINCLUD1.
If you run ZMASTER2, the source code of include program ZINCLUD1 is changed and replaced in the system. However, the last line of ZMASTER2 executes the older version since the runtime object of ZMASTER2 is generated before ZINCLUD1 is modified. Only when ZMASTER2 is run a second time, does the system determine that ZINCLUD1 has been changed. Exactly the same is true if you dynamically modify the source code of a subroutine and call it from within the same program.
One way to solve this problem is to use the INCLUDE statement within an external subroutine that is called by the program. This allows you to create or modify include programs or subroutines and use the updated versions directly in the same program.
Assume the following include program:
INCLUDE ZINCLUD1.
WRITE / 'Original INCLUDE program!'.
and an external subroutine:
PROGRAM ZFORM1.
FORM SUB1.
INCLUDE ZINCLUD1.
ENDFORM.
The following program reads the include program, modifies it, enters it back into the system, and calls the subroutine.
REPORT ZMASTER3.
DATA CODE(72) OCCURS 10.
READ REPORT 'ZINCLUD1' INTO CODE.
APPEND 'WRITE / ''Extension of INCLUDE program!''.' TO CODE.
INSERT REPORT 'ZINCLUD1' FROM CODE.
PERFORM SUB1(ZFORM1).
This produces the following output:
Original INCLUDE program!
Extension of INCLUDE program!
In this case, the updated version of the include program is used in the subroutine because its time stamp is checked when the subroutine is called, and not when the calling program is generated.

Call selection screen from normal screen of modulpool

Hey gurus,
I would like to call a selectionscreen when I press a button on my normal screen in modulpool, but it doesn't work.
I made a modulpool with a normal screen where is that button. In the top include I made a selection screen followingly:
SELECTION-SCREEN BEGIN OF SCREEN 1001 as SUBSCREEN.
   PARAMETERS: rb1 RADIOBUTTON GROUP ab MODIF ID bl2,
             rb2 RADIOBUTTON GROUP ab MODIF ID bl2.
SELECTION-SCREEN END OF SCREEN 1001.
but it writes out an error when i try to call subscreen 1001.
What's wrong? How could I achieve my goal?
Thank you very much.
Regards,
Robert

Calling a Selection Screen from a Function Module/Method

Hi,
I would like to call a selection screen from a function module or method. I understand it is not possible by the definition. Are there any alternative options as I am looking for the Variants Save option on the screen. Any thoughts?
Thanks
Raghav

Since i don't know your exact requirements (standard SAP selection screen? your own selection screen?) the onl;y thing i can come up with is:
1. in your function pool create your own screen with a subscreen area
2. create your own selection screen as a subscreen.
3. include the selection subscreen in the first screen
4. call the first screen in your function.

Problem in creating selection screen from screen painter

hi ,
      i am working with screens i have created a screen and in that wehn i click report button it has to ask for select options for dates.from there i will write a select quesry based on selection dates ...how to call a selection screen from screen.i created an include and in that include i used select options.but it is showing error message .guide me how to do it ?

Hi..
Here for your problem,
I have created a button with function code 'CLICK' in screen no 1000.
when I click on the button I am capturing the ok_code and displaying the selection screen.
ok_code = sy-ucomm.
case:ok_code.
when 'CLICK'.
         SELECTION-SCREEN BEGIN OF SCREEN 500 TITLE title.
         SELECT-OPTIONS: P_DATE for sy-datum.
         SELECTION-SCREEN END OF SCREEN 500.
title = 'Input Date'.
CALL SELECTION-SCREEN '0500'.
endcase.
You can also have them as subscreen by providing the required parameters in the selection screen.
Hope this solves your problem.
Warm Regards,
Bhuvaneswari.

hi,
You can call one selection screen from other selection screen program using SUBMIT command.
The syntax is as follows -
codeSUBMIT... VIA SELECTION-SCREEN
USING SELECTION-SET <var>
WITH <sel> <criterion>
WITH FREE SELECTIONS <freesel>
WITH SELECTION-TABLE <rspar>.[/code]
e.g.
The following executable program (report) creates a selection screen containing the parameter PARAMET and the selection criterion SELECTO:
codeREPORT demo_program_submit_rep1.
DATA number TYPE i.
PARAMETERS paramet(14) TYPE c.
SELECT-OPTIONS selecto FOR number.[/code]
The program DEMO_PROGRAM_SUBMIT_REP1 is called by the following program using various parameters:
codeREPORT demo_program_submit_sel_screen NO STANDARD PAGE HEADING.
DATA: int TYPE i,
rspar TYPE TABLE OF rsparams,
wa_rspar LIKE LINE OF rspar.
RANGES seltab FOR int.
WRITE: 'Select a Selection!',
SKIP.
FORMAT HOTSPOT COLOR 5 INVERSE ON.
WRITE: 'Selection 1',
/ 'Selection 2'.
AT LINE-SELECTION.
CASE sy-lilli.
WHEN 4.
seltab-sign = 'I'. seltab-option = 'BT'.
seltab-low = 1. seltab-high = 5.
APPEND seltab.
SUBMIT demo_program_submit_rep1 VIA SELECTION-SCREEN
WITH paramet eq 'Selection 1'
WITH selecto IN seltab
WITH selecto ne 3
AND RETURN.
WHEN 5.
wa_rspar-selname = 'SELECTO'. wa_rspar-kind = 'S'.
wa_rspar-sign = 'E'. wa_rspar-option = 'BT'.
wa_rspar-low = 14. wa_rspar-high = 17.
APPEND wa_rspar TO rspar.
wa_rspar-selname = 'PARAMET'. wa_rspar-kind = 'P'.
wa_rspar-low = 'Selection 2'.
APPEND wa_rspar TO rspar.
wa_rspar-selname = 'SELECTO'. wa_rspar-kind = 'S'.
wa_rspar-sign = 'I'. wa_rspar-option = 'GT'.
wa_rspar-low = 10.
APPEND wa_rspar TO rspar.
SUBMIT demo_program_submit_rep1 VIA SELECTION-SCREEN
WITH SELECTION-TABLE rspar
AND RETURN.
ENDCASE.[/code]
=> To leave a called program, you can use SUBMIT .... AND RETURN. by choosing F3 or F15 from list level 0 of the called report.

Going back to selection screen from ALV

Hi there,
I have scenario: program -> selection screen -> ALV
In the 'BACK' button I have put: LEAVE TO SCREEN 0. It should go back to selection screen. But it does not and exits the program. I also tried to call the selection screen like CALL SELECTION-SCREEN 1000. But in this case if I hit BACK on selection screen, it goes back to previous screen, the ALV not the program. Can you please assist any other way to use the back button from
ALV -> Selection screen. Thanks.

Go back selection-screen from level2 of cl_salv_hierseq_table

Hi,
Problem is to go back on selection screen in one go using BACK , CANCEL or EXIT button
cl_salv_hierseq_table is being called to display output list.
Same class cl_salv_hierseq_table is being used to display new list if user wants to see.
All output list goes into ABAP stack.
Neither a single standard button BACK , CANCEL or EXIT allow me to go back on selection-screen directly from 2 level onwards . it goes one by one level
Copied GUI-status to use on_user_command and tried to use LEAVE TO TRANSACTION / CALL TRANSACTION but selection screen values in select-options / parameters not retrived
How to back on selection-screen from level2 onwards and see all values which are entered initially
Thanks
ammonin

Hi,
No custom screen is created in my program for displaying result.
Calling METHOD display of CL_SALV_HIERSEQ_TABLE ,
So every time each DISPLAY method goes into stack .
In degug , I found FM REUSE_ALV_HIERSEQ_LIST_DISPLAY is being called
As per your suggestion it happens only when I am on first level of display result
If I am calling same METHOD display for another output without distroying exsiting one. it stores in ABAP stack
I do not know how to initializie existing / Kill CL_SALV_HIERSEQ_TABLE session before calling it again
Standard button BACK/EXIT/CANCEL does
SET SCREEN 0
LEAVE SCREEN and goes back to only one level back not on directly on selection screen.
If it is on first level then only selection-screen comes with values.
Thanks
Amy

Call selection screen in fm

Hi all!
I have a report, and i have a selection screen in a fm. Report call fm, and it bring me selection parameters.
However i need run report in background, but option (F9) for do this, not visible. Somebody have any idea
for resolve this ?
pd: i should use fm. not using selection screen in traditional way.
Thanks for ur answer.

I'm not sure if anyone is looking for an answer here still, but I'll attempt an answer.
Class Based exceptions cannot be propogated from a section of code that does not have a local memory area. This means Event (START-OF-SELECTION, AT SELECTION-SCREEN, etc) and Dialog Processing. Since the exception cannot be propogated, it hits the system and the system treats it as a dump scenario. In addition, due to the way Class Based Event Handling is processed, an exception cannot be propogated past an event handler.
I am not sure if there is a work around for your problem though. One way may be to use a variable to store the exception that occurred; then when the Function Module itself has control again, check to see if that variable contains a value, it will raise the exception to the application that called the function. Using this and checks against this variable, you would be able to prevent further processing after the exceptions actual occurance.
Global Data Definition
DATA iException TYPE I VALUE 0 .
Function Module
CALL SELECTION-SCREEN 1234
CASE iException .
WHEN 0 .
   " do nothing, no exception occurred on selection screen.
WHEN 1 .
     RAISE EXCEPTION CX_Your_Exception_Name .
ENDCASE .
AT SELECTION-SCREEN OUTPUT .
IF [some condition] .
    iException = 1 . "If your exception occurred.
ENDIF .
This would allow you to use a global variable to log the exception and report it back to the function module; this will then allow the function module to propogate the correct exception back to the calling procedure.

CALL SELECTION SCREEN problem

Hello!
I have a problem. In my riport I have a selection screen (1000), a main screen (2000), and a screen (400) this is called inside a loop, to fill some datas when you hit the print button.
CLEAR L_TOTAL.
SORT LT_EBAN BY BNFPO.
LOOP AT LT_EBAN.
    GT_ITEM2-FIELD01 = SY-TABIX.
    GT_ITEM2-FIELD02 = LT_EBAN-MATNR.
*---Part name, Type, Maker
    SPLIT LT_EBAN-TXZ01 AT ',' INTO GT_ITEM2-FIELD03 GT_ITEM2-FIELD04 GT_ITEM2-FIELD05.
     CONCATENATE GT_ITEM2-FIELD03 '/' GT_ITEM2-FIELD04 INTO DESCR.
     ITEM = LT_EBAN-BNFPO.
     CALL SCREEN 400 STARTING AT 20 7 ENDING AT 60 18.
*---Machine
    GT_ITEM2-FIELD06 = ST_400-MACHINE.
After this, i could not use the LEAVE TO SCREEN 0, because it's not going back to secreen '2000' , I'm getting a blank 400 screen.
Thatswhy I used CALL SCREEN '2000', and it's fine.
But in the case of the Selection screen (1000) something is wrong.
On the screen 2000 I using this logic.
MODULE EXIT_2000 INPUT.
CASE OK_CODE.
    WHEN 'BACK' OR 'EXIT'.
      CLEAR OK_CODE.
       CALL SELECTION-SCREEN '1000'.
       LEAVE PROGRAM.
    WHEN 'CANC'.
      PERFORM EXIT_PROGRAM.
      LEAVE PROGRAM.
ENDCASE.
CLEAR OK_CODE.
ENDMODULE.                 " exit_2000 INPUT
With this logic, the program is going to the SELECTION-SCREEN, when I hit the back button, and when we are already on the SELECTION-SCREEN, it's leaving the program. This is also ok.
But when I hit the back button, and on the SELECTION-SCREEN I want to run the program again, it's not going to the program logic, it's jumping to this CALL SELECTION-SCREEN '1000', and leaving of course.
START-OF-SELECTION.
PERFORM DSP1_PROC.
IF GT_DISPLAY[] IS INITIAL.
    MESSAGE S208(00) WITH 'No data.'.
    EXIT.
ENDIF.
IF S_RET = '1'.
    MESSAGE I208 WITH 'Document not found'.
    S_RET = ' '.
ELSE.
    S_RET = ' '.
    CALL SCREEN '2000'.
ENDIF.
So my question is, that the above logic, when I running the program first time It's working good, at the START-OF-SELECTION, but when I trying to runnig from the SELECTION-SCREEN "second time", from the   START-OF-SELECTION it's jumping to the CALL SELECTION-SCREEN '1000'. How can I avoid this. I want that from the START-OF-SELECTION, never go to the CALL SELECTION-SCREEN '1000'.
Thank You

Hi Max!
Yeah, I was thinking the same, that the problem is with that loop.
But I don't know, how can I solved in a different way, because when we hit the print button, we getting all the items from a table, and we starting looping on them. In the loop we passing the values to a GT_ITEM table, later this table is connected with an excell, so it will be printed out in an excell form.
So I have to call this screen so many times, how many items we have. Sometimes just 1, sometimes 4, 6, 9, and so on.
For this items I have to add 2 more fields, wich are uploaded by the user. ( The other fields are coming from the table)
So if I going out from the loop after the CALL SCREEN 400, I think the next item wont be get the values. Or maybe any of them, because this is before the APPEND GT_ITEM. So this methode wont be called, no data would be in the table, nothing will be printed.

Call Selection Screen

Hi,
can any one give me good links for
All variants of at selection screen..
some thing on call selection screen
Thx,
Shashi

·     AT SELECTION-SCREEN
You should only perform very expensive checks with AT SELECTION-SCREEN if the program is then started. Here, you can read the system field SSCRFIELDS-UCOMM (provided a statement TABLES SSCRFIELDS exists). If the field has one of the values 'ONLI' (= Execute) or 'PRIN' (= Execute and Print), the report is then started, i.e. the selection screen is closed and the processing continues with START-OF-SELECTION.
     Additions:
·     ... ON psel
Effect
This event is assigned to the selection screen fields corresponding to the report parameter or selection criterion psel.
If the report starts an error dialog at this point, precisely these fields become ready for input.
·     ... ON END OF sel
          For each selection criterion sel on the selection screen, you can call a further screen by pressing a pushbutton. On this screen, you can enter any number of single values and ranges for the selection criterion sel..
When this screen has been processed (i.e. at the end of PAI for this screen), the event AT SELECTION-SCREEN ON END OF sel is executed.
At this point, all the values entered are available in the internal table sel.
·     ... ON VALUE-REQUEST FOR psel_low_high
Effect
In this addition, the field psel_low_high is either the name of a report parameter or of the form sel-LOW or sel-HIGH, where sel is the name of a selection criterion. The effect of this is twofold:
1.     The possible entries pushbutton for F4 appears beside the appropriate field.
2.     When the user activates this pushbutton or presses F4 for the field, the event is executed. You can thus implement a self-programmed possible entries routine for the input/output fields of the selection screen. If the program contains such an event and the user presses F4, the system processes this rather than displaying the check table or the fixed values of the Dictionary field.
·     ... ON HELP-REQUEST FOR psel_low_high
Effect
As with the addition ON VALUE-REQUEST the field psel_low_high is either the name of a report parameter or of the form sel-LOW or sel-HIGH, where sel is the name of a selection criterion. When the user presses F1 on the relevant field, the subsequent processing block is executed. You can thus implement a self-programmed help for the input/output fields of the selection screen. If the program contains such an event and the user presses F1, the system processes this rather than displaying the documentation of the Dictionary field - even if the report parameter or the selection option with LIKE or FOR points to a Dictionary field.
·     ... ON RADIOBUTTON GROUP radi
Effect
This event is assigned to the radio button groups on the selection screen defined by PARAMETERS par RADIOBUTTON GROUP radi. If the report starts at an error dialog at this point ,precisely these fields of the radio button group
radi become ready for input again.
·     ... ON BLOCK block
Effect
This event is assigned to the blocks on the selection screen defined by SELECTION-SCREEN BEGIN/END OF BLOCK block. If the report starts at an error
dialog at this point, precisely these fields of the block block become ready for input again.
     The events assigned to the radio button groups are executed according to the first parameter of the radio button group.
The events assigned to the blocks are executed "from the inside to the outside".
·     ... OUTPUT
Effect
This event is executed at PBO of the selection screen every time the user presses ENTER - in contrast to INITIALIZATION. Therefore, this event is not suitable for setting selection screen default values. Also, since AT SELECTION-SCREEN OUTPUT is first executed after the variant is imported (if a variant is used) and after adopting any values specified under SUBMIT in the WITH clause, changing the report parameters or the selection options in AT SELECTION-SCREEN OUTPUT would destroy the specified values. Here, however, you can use LOOP AT SCREEN or MODIFY SCREEN to change the inout/output attributes of selection screen fields.
·     ... ON EXIT-COMMAND
Effect
This event is executed at the exit command of the selection screen - that is, at Back, Cancel, or End,events executed after the screen is sent that do not cause the system to check the input and execute the PAI.
plz reward if useful
