Validation on selection screen parameter.

I have select options in my selection screen.
1) s_a
2) s_b
Requirement:-
1) If I run the program and click the arrow on the "s_a" field, it should open multi selection screen. From that I can make multi entry or upload data from excel file.
2) If "s_a" and "s_b" is empty it sud throw an error message.
Can I do this validation in AT SELECTION-SCREEN n how?

hi Abhijeet,
u can do the first by just writing the sel-options as:
S_A like table-field (say vbak-vbeln). then the multiple selection comes automatically.
the second - u can do thru at selection-screen by just writing a if condition.
if s_a-low is initial and s_a-high is initial.

Let me know if you still have any issue.

Multiple select options validation at selection screen

Hi,
I have the requirement to create a selection screen with 3 select options. Two of them are cross-dependent. It is mandatory to fill one of them and it is not allowed to fill both. The third one is optional. I tried the validation at selection-screen on block... and I have a problem that search help buttons for select options react like execution buttons, when I press any of them I am getting one of errors instead of search help.
Any help on this issue would be appreciated.
Here is my code:
DATA:
 so_rbkp TYPE rbkp,
 so_mseg TYPE mseg.
SELECTION-SCREEN BEGIN OF BLOCK blok WITH FRAME.
SELECT-OPTIONS:
 s_fakt FOR so_rbkp-belnr,
 s_matdok FOR so_mseg-mblnr,
 s_god FOR so_mseg-gjahr.
SELECTION-SCREEN END OF BLOCK blok.
INITIALIZATION.
SET TITLEBAR '0100'.
START-OF-SELECTION.
AT SELECTION-SCREEN on block blok.
 if s_fakt <> space and s_matdok <> space.
 MESSAGE 'Message1' TYPE 'E'.
 elseif s_fakt = space and s_matdok = space.
 MESSAGE 'Message2' TYPE 'E'.
 endif.
 ENDIF.

Only perform the check when user wants to execute or submit the program, not when pressing F4 or even Enter, but in a selection-screen event, before START-OF-SELECTION which were program would terminate in error :
TABLES: SSCRFIELDS.
AT SELECTION-SCREEN OB BLOCK b01.
 IF sscrfields-ucomm EQ 'ONLI'
 OR sscrfields-ucomm EQ 'PRIN'
 OR sscrfields-ucomm EQ 'SJOB'.
 IF s_fakt[] IS NOT INITIAL AND s_matdok IS NOT INITIAL.
 MESSAGE 'Message1' TYPE 'E'.
 ELSEIF s_fakt[] IS INITIAL and s_matdok[] IS INITIAL.
 MESSAGE 'Message2' TYPE 'E'.
 ENDIF.
 ENDIF.
(You could also always send the message, but using type 'E' for those function code and 'S' status for any other value.)

Calling another report by passing selection screen parameter

Hi,
I have created a report "ZREPA" with selection screen parameter say, "creator".
Nw, i hv to call that report "ZREPA" from another report say "ZREPB" by passing an value to the selection screen field "creator".
Can anyone tell me how to resolve this??
Thanks,

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:
REPORT 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.
=> To leave a called program, you can use SUBMIT .... AND RETURN. by choosing F3 or F15 from list level 0 of the called report.

 3) If invoice list is selected, then the message type must be selected
 4) Validate the message type field entered.

Hi Sen 001
It depends how you want to validate. If you want to validate immediately after the user put a check box or enter value then you shoul use <AT SELECTION SCREEN> event and <USER-COMMAND> following your parameters (or select-options) in your selection screen. You can also validate when user presses F8, where you should put your validation inside <START-OF-SELECTION> event.
Example to immediate validate after check box entered
SELECTION-SCREEN: BEGIN OF BLOCK b02 WITH FRAME.
PARAMETERS: p_grp RADIOBUTTON GROUP gr1 DEFAULT 'X' USER-COMMAND zcomm,
 p_dst RADIOBUTTON GROUP gr1.
SELECTION-SCREEN: END OF BLOCK b02.
AT SELECTION-SCREEN.
IF sy-ucomm(6) = 'ZCOMM'.
 PERFORM xxx.
ELSE.
 PERFORM yyy.
ENDIF.

Selection screen parameter validation using search help/check table

Hi experts,
I have a select-option that is tied to a search help and check table (type tq80-qmart). Is there a way to automatically validate the field based on what comes up in the F4 search help? What I mean is, when the user hits F4 on the parameter, the list pops up with several records that the user can choose. When the program is executed, I want the program to show an error if the value is NOT in that F4 list.
I know this can be done in AT SELECTION SCREEN event with a select, but I was wondering if there was a way ABAP does it automatically. Any help will be greatly appreciated.
Thanks,
Juan

Hello Juan,
SAP does have a standard way of allowing the the user to select from the list via LISTBOX.
But list box is restricted to parameters only, you cannot attach list boxes to select-options.
I think the best place to do this validation would be th AT SELECTION-SCREEN event & from your original post it seems you know what code to write

Validating a selection-screen field

Anil.

Make sure that u are validating against the header table.
say eg if u wnat t validate matnr in marc, then do as below.
SELECT-OPTIONS: s_matnr FOR marc-matnr. "Material No
AT SELECTION-SCREEN.
*Validate material no details
PERFORM validate_matno.
FORM validate_matno.
DATA: v_matnr LIEK mara-matnr.
SELECT SINGLE matnr INTO v_matnr
 FROM mara
 WHERE matnr IN s_matnr.
IF sy-subrc NE 0.
 MESSAGE i128.
 LEAVE LIST-PROCESSING.
ENDIF.
ENDFORM.
Dont select from marc.
Hope this is clear.

You can give F4 help by two ways:

2. Refering db table field.

Validating a selection screen filed

Hi Experts,
I need to to validate a selection screen field .The field is mentioned as selection parameter and it is obligatory.
To validate this i have written the logic as follows:
AT SELECTON SCREEN ON <FIELD-NAME>.
SELECT STATEMENT.
IF SY-SUBRC NE 0.
ERROR MESSAGE.
endif.
But here my question is select-options acts like an intenal table,Inthis case do we need to loop to the select-options fields or else do we have any other alternative solution.
Edited by: vinay raj on Aug 31, 2010 10:51 AM

Hi,
Looping is not required for this validation. And as you have said select statement using IN oerator does not throw any error message if the value is not present in select-options.
AT SELECTON SCREEN ON <FIELD-NAME>.
SELECT STATEMENT .... where field in s_field.
IF SY-SUBRC NE 0.
ERROR MESSAGE.
endif.
But if you want to check whether the value entered in select-options is invalid then you can refer the below sample code
which can be used to check for the validity of the value of valuation class entered in the selection screen where valuation class is used as select-options. In the below code table T025 has all the values of valuation class. If the entered value does not exist in this then it indicates that the value entered in selection screen is invalid.
AT SELECTON SCREEN ON <FIELD-NAME>.
PERFORM check_valuation_class.
FORM check_valuation_class.
DATA : lv_bklas TYPE bklas.
IF NOT p_bklas-low IS INITIAL.
 SELECT SINGLE COUNT(*) FROM t025
 INTO (lv_bklas) WHERE bklas EQ p_bklas-low.
 IF sy-subrc NE 0.
 MESSAGE e021(zfm001).
 ENDIF.
ENDIF.
IF NOT p_bklas-high IS INITIAL.
 SELECT SINGLE COUNT(*) FROM t025

Need to validate selection screen parameter valus

Hi all,
we have a requirement to validate parameter values ,
parameter values should be less than or equal to 12 and should accept 2 decimals .
how to declare parameter?
eg: 11.34, 12.00
regards
sridhar

should accept 2 decimals .
PARAMETERS : p1 type p DECIMALS 2.
this automatically comes with validation.
and for less than 12, keep logic in at selection-screen event.
both AT SELECTION-SCREEN. and AT SELECTION-SCREEN. on p1 works.
AT SELECTION-SCREEN.
IF p1 > 12.
MESSAGE 'Provide values less than 12' type 'E'.
ENDIF.
and
AT SELECTION-SCREEN ON p1.
IF p1 > 12.
MESSAGE 'Provide values less than 12' type 'E'.
ENDIF.
the difference between these tow is the later displays the error on that particular field (useful when you have multiple fields in selection screen)
hope this helps.
