Slection Screen Validations

Hi Experts,
Could any one provide me the material for selection screen validations
Ex: In selection Initial screen, I have 2 radio buttons. Based on selecting the radio button, the input selection screen should be displayed below the radio buttons?
like these provide me diff examples and also provide me the materials for these
Thanks,
Sanju

Hi Sanjana,
U can use the AT SELECTION-SCREEN event to do the necessary validation and checks..so in your case if a particular is mandatory for rd1 and not for rd2..in that case please take out the obligatory clause from the parameter and do the validation in the above event..basically if rd1 is selected and the particular parameter is blank ..display an error message.
check this sample code.
REPORT ztest.
TABLES: mara,vbak.
PARAMETERS: r_m RADIOBUTTON GROUP g1 DEFAULT 'X' USER-COMMAND ABC,
            r_s RADIOBUTTON GROUP g1.
parameters: p_matnr like mara-matnr,
                p_vbeln like vbak-vbeln.
AT SELECTION-SCREEN OUTPUT.
IF r_m = 'X'.
    LOOP AT SCREEN.
      IF screen-name = 'P_VBELN'.
        screen-input = 0.
        MODIFY SCREEN.
      ENDIF.
    ENDLOOP.
ELSE.
    LOOP AT SCREEN.
      IF screen-name = 'P_MATNR'.
        screen-input = 0.
        MODIFY SCREEN.
      ENDIF.
    ENDLOOP.
ENDIF.
AT SELECTION-SCREEN.
<b> IF sy-ucomm = 'ONLI'.</b>
    IF r_m = 'X'.
      IF P_matnr IS INITIAL.
        MESSAGE e000(zz) WITH 'error'.
      ENDIF.
    ENDIF.
ENDIF.

Problem in AT selection screen validation

Hi,
I am having problem in AT SELECTION SCREEN Validation.
I have 2 radiobutton and 6 parameter. if i click first radio button all the 6 radiobutton should enable and take the user input, that is working fine for me.
if i click second radiobutton , out of 6 , 3 parameter should disable and remaining 3 should enable. thats also working fine.
My problem is program has written the validation for this 3 parameter in the AT SELECTION SCREEN.
For first radioutton all the validation working fine, for second validation as soon as i press the radiobutton it will display error message. Based on 2 parameter user is filling value for 3 rd parameter.
I want the same validation to be done for second radio button after user pressing enter.
PARAMETER: p_single RADIOBUTTON GROUP rad1 DEFAULT 'X' USER-COMMAND f1,
           p_multi RADIOBUTTON GROUP rad1.
PARAMETERS: s_pwwrk LIKE plaf-pwwrk.
PARAMETERS: p_lgort LIKE plaf-lgort.
PARAMETERS: p_kostl LIKE cobl-kostl.
here is my code:
AT SELECTION SCREEN.
CLEAR t001w.
CLEAR t001k.
CLEAR marv.
SELECT SINGLE * FROM t001w WHERE werks EQ s_pwwrk.
IF sy-subrc NE 0.
    MESSAGE e999 WITH 'Plant' s_pwwrk 'does not exist'.
ELSE.
    SELECT SINGLE * FROM t001k WHERE bwkey EQ t001w-bwkey.
    SELECT SINGLE * FROM marv WHERE bukrs EQ t001k-bukrs.
    IF p_budat0(4) NE marv-lfgja OR p_budat4(2) NE marv-lfmon
IF marv-xruem IS NOT INITIAL.
        IF p_budat0(4) NE marv-vmgja OR p_budat4(2) NE marv-vmmon.
MESSAGE e999 WITH p_budat4(2) p_budat0(4)
                            'is closed.
                                        Please try again.'.
        ENDIF.
      ELSE.
        MESSAGE e999 WITH p_budat4(2) p_budat0(4)
                          'is closed.
                                      Please try again.'.
      ENDIF.
    ENDIF.
ENDIF.

For your Case ,
If i understand clearly,You can do the validation when you want on AT SELECTION SCREEN ON WP_FIELD.
If you say your validation to be done only for Selection of Second Radio Button, then..
AT SELECTION SCREEN.
if p_multi eq 'X'. "<- Make Validation to be done only if user select Second Button
CLEAR t001w.
CLEAR t001k.
CLEAR marv.
SELECT SINGLE * FROM t001w WHERE werks EQ s_pwwrk.
IF sy-subrc NE 0.
MESSAGE e999 WITH 'Plant' s_pwwrk 'does not exist'.
ELSE.
SELECT SINGLE * FROM t001k WHERE bwkey EQ t001w-bwkey.
SELECT SINGLE * FROM marv WHERE bukrs EQ t001k-bukrs.
IF p_budat+0(4) NE marv-lfgja OR p_budat+4(2) NE marv-lfmon
IF marv-xruem IS NOT INITIAL.
IF p_budat+0(4) NE marv-vmgja OR p_budat+4(2) NE marv-vmmon.
MESSAGE e999 WITH p_budat+4(2) p_budat+0(4)
'is closed.
Please try again.'.
ENDIF.
ELSE.
MESSAGE e999 WITH p_budat+4(2) p_budat+0(4)
'is closed.
Please try again.'.
ENDIF.
ENDIF.
ENDIF.
endif.

HOW TO IMPLEMENT SCREEN VALIDATION IN LDB?

Hi,
I am making use of Logical Database in my report, and I want to do screen validation with the screen which already exists in the system? Is it possible to do so? If yes, then how? The LDB, I am using is PSJ.
Also, I would like to know, can we define our own selection screen incase of LDB? How is that possible if the answer is yes to it.BUt here I am not talking about dynamic selection screen. What I mean to say is that..., can we restrict the selection screen in LDB, by defining the fields which are required in the selection screen on execution of the report?
Someone, please guide.
Points will be rewarded for a satisfactory answer.
Thanks & Regards,
Ravi

Hi Ravi,..
Chk out the link - http://help.sap.com/saphelp_erp2005/helpdata/en/60/183d78163011d2953c0000e8353423/frameset.htm
Yes, we can define our own selection screen and that will come right below your LDB selection screen.
AND also LDB selection screen can be restricted ..for this you have to code in PBO of report for hiding the elements which u don't required.

Selection-screen validation

Hi Experts,
Please can any one give me the details ..
1)What is the actual use of selection screen validation?
2) When we use Selection-screen validation?
3)If we are not written the selection-screen validation is there any effect?
I know how to write the validation for a selection screen. But why i am asking above questions is I am very new to ABAP .My Functionl people also new to ABAP. They told me one report.I asked me what are the validation for selection screen . At that time they told there is no validation.
Thats the reason to ask above questions..
please tell me the details..
Thanks In Advance..
Thanks and Regards
Siri..

Abhi,
Selection Screen Validation are used for correct input processing.
Selection screen elements are used further in select queries to fetch data. if user enters some wrong input
we will unnecessarily hit the data base with wrong values and select will fail , hence validation of the input
will avoid unnecessary data base hit.

Problem in selection screen validation.

Hi All,
I am having the following in the selection screen:
PARAMETERS : p_r1 RADIOBUTTON GROUP grp DEFAULT 'X' USER-COMMAND dlvy,
             p_r2 RADIOBUTTON GROUP grp .
SELECTION-SCREEN BEGIN OF BLOCK b1 with frame title text-001.
SELECT-OPTIONS: s_vbeln FOR lips-vbeln             MODIF ID dly.
SELECT-OPTIONS: s_lfart FOR likp-lfart OBLIGATORY MODIF ID dly.
SELECT-OPTIONS: s_vstel FOR likp-vstel             MODIF ID dly.
SELECT-OPTIONS: s_matnr FOR lips-matnr             MODIF ID dly.
SELECT-OPTIONS: s_wadat FOR likp-wadat OBLIGATORY MODIF ID dly.
SELECT-OPTIONS: s_wbsta FOR vbup-wbsta             MODIF ID dly.
SELECTION-SCREEN END OF BLOCK b1.
SELECTION-SCREEN BEGIN OF BLOCK b2 with frame title text-002.
SELECT-OPTIONS: s1_matnr FOR lips-matnr MODIF ID mat.
SELECT-OPTIONS: s_extwg FOR mara-extwg MODIF ID mat.
SELECT-OPTIONS: s_werks FOR marc-werks MODIF ID mat.
SELECTION-SCREEN END OF BLOCK b2.
If I choose Radio Button 1, only option 1 should be triggered,
If I choose Radio Button 2, only option 2 should be triggered,
For this I have:
AT SELECTION-SCREEN OUTPUT.
IF p_r1 = 'X'.
    blk_hide = 'MAT'.
    blk_show = 'DLY'.
ELSE.
    blk_hide = 'DLY'.
    blk_show = 'MAT'.
ENDIF.
LOOP AT SCREEN.
    IF screen-group1 = blk_hide.
      screen-active = 0.
    ELSE.
      IF screen-group1 = blk_show.
        screen-active = 1.
      ENDIF.
    ENDIF.
    MODIFY SCREEN.
ENDLOOP.
Now I need to validate the selection Screen, I am facing issue in doing selection screen validation:
Can any one help me in how to go about this?
Thanks,
Debrup.

pls. replace the AT SELECTION-SCREEN OUTPUT event with this one:
AT SELECTION-SCREEN OUTPUT.
LOOP AT SCREEN.
    CASE 'X'.
      WHEN p_r1.
        CASE screen-group1.
          WHEN 'DLY'.
            screen-active = '1'.
          WHEN 'MAT'.
            screen-active = '0'.
        ENDCASE.
      WHEN p_r2.
        CASE screen-group1.
          WHEN 'DLY'.
            screen-active = '0'.
          WHEN 'MAT'.
            screen-active = '1'.
        ENDCASE.
    ENDCASE.
    MODIFY SCREEN.
ENDLOOP.

Screen validations

Hi Experts,
How can i do the screen validations with Ranges. The below is the Description in the Func. Specs.
Posting date-FAGLFLEXA-BUDAT-Range with F4 help on date. Single Multiple values should also work
G/L Account-FAGLFLEXA-RACCT-Range with F4 help. Single Multiple values should also work
Validation: Verify that this FAGLFLEXA-RACCT is maintained as KONTS in the table T030K. The chart of account T030K-KTOPL required to access this table can be found by entering Company code BUKRS into table V_001_S and pick up V_001_S-KTOPL.
Thanks & Regards,
Ramana

As per your question u are using select-option.
select-option is nothing but it creates internal table.
suppose if u r using S_date then it creates internal table of same name containing sign,opt,low, high columns
If you put range then s_date-low contains <lower limit> & s_date-high higher <higher limit>
i.e.
s_date = 01.05.2008 to 05.05.2008
then
s_date-low = 01.05.2008
s_date-high = 05.05.2008
like that
and if you put multiple values like diffrent dates
then i appends that multiple date in to s_date-low
ie
s_date = 01.05.2008
              03.05.2008
              06.05.2008
then it will appear as
sign     opt       low             high
I         EQ     01.05.2008
I         EQ     03.05.2008
I         EQ     06.05.2008
in select option.
Now i guess u will clear with the select option concept
Accordingly you can use LOOP STATEMENT on S_DATE
either in AT-SELECTION screen or in INITIALIZATION
Hope you will get an Answer

AT SLECTION-SCREEN

HI
what is the difference between AT SELECTION-SCREEN and AT SELECTION-SCREEN-OUTPUT.
PBO + AT SELECTION SCREEN = AT SELECTION SCREEN OUTPUT?
like based on 1st screen validations 2nd screen has to enable or disable.

This simple program says all..
TABLES: MKPF.
DATA: ITAB LIKE STANDARD TABLE OF MSEG.
PARAMETERS: P_MBLNR LIKE MKPF-MBLNR,
            P_DATE LIKE MKPF-CPUDT.
AT SELECTION-SCREEN OUTPUT.
LOOP AT SCREEN.
    IF SCREEN-NAME EQ 'P_MBLNR'.
      SCREEN-REQUIRED = 1.
      MODIFY SCREEN.
    ENDIF.
ENDLOOP.
AT SELECTION-SCREEN.
SELECT SINGLE * FROM MKPF WHERE MBLNR EQ P_MBLNR.
IF SY-SUBRC NE 0.
    MESSAGE 'Not exists' TYPE 'E'.
ENDIF.

Screen validation for BAPI_ENTRYSHEET_CREATE

Hi All,
We are using BAPI_ENTRYSHEET_CREATE to create entry sheet for work orders,
we are passing WBS element to table parameter 'entrysheetaccountassignment 'and entry sheet created successful,
if we passing incorrect WBS element,BAPI is not validating(through transaction it's validating),
Entry sheet created succecdully but , if we check in transaction ML83 the WBS field is blank,
how to check screen validation,
Regards,
Suresh.D
Edited by: suresh dameruppula on Apr 23, 2010 2:37 PM

Hi,
this BAPI does not perform validation. It just converts WBS from external format into internal format. In case of invalid conversion it clears WBS element field. Hence if you want to have a WBS validation then you need to do it by yourself using BAPI BAPI_PROJECT_EXISTENCECHECK.
Cheers

Selection screen validation when using PNP LDB

Hi guys,
I want to validate my selection screen parameters.Thats is if somebody wants to run the program without giving any input parameters to the selection screen(trying to run the report with a blank screen) I want to pop up an error/information message so that it will return the selection screen.I am using PNP Logical database for my selection screen.Please help.Thanks in advance.
Thanks,
Karthik.

Welcome to SDN.
If you are using PNP logical data base then validating the fields will be little tricky...
You canc check all the other fields in START-OF-SELECTION and if they are empty return eroor. Remember all the field s on the scree... so I will suggest you to choose HR report Category accordingly.
Also,when it comes to date field then you need to check for the start and end dates rather than blank fields as SAP defaulted them to system start and end date.
Still, I will prefer to create a HE Report Category for the PNP database and use the screen while validating....that will be easy...

Selection-screen validations

Hi Experts ,
I have module pool program there in first screen user have choice to select screen if user select the first screen .The selection will be displayed with two parameters using key word
selection-screen begin of screen 2002.
parameters : p_date type sy-datum,
                     p_num type kunnr.
selection-screen end of screen 2002.
call screen '2003'.
now i want to do validations on these parameters ,
please let me know how can i validate these selection-screen fields there i try chain and endchain in screen 2003 , it says no fields in screen 2003. screen 2002 was developed dynamically by systemplease let me know how to do validations i search it i cant find it plz solve issue .

hi
i think there are two methods two create selection screen
1. using layout here we can create selection screen with screen painter
here we can validate using chain end endchain.
Plz try this on
Selection Screen
Defined within an ABAP program; called by the runtime environment or using the CALL SELECTION-SCREEN statement; processed in event blocks of the corresponding ABAP program.
in main screen we have 3 selections for screen 2002 ,2004, 2006.
if sy-ucomm = 2002.
2 . selection-screen begin of screen 2002.
parameters : .........
      selection-screen end of screen 2002.
call selection-screen '2002'.
once this was triggered after entering vales it return to the next step then
call screen 2003.
then it goes to PBO and PAI events.
endif.
if sy-ucomm = 2003.
selection-screen begin of screen 2003.
parameters : .........
      selection-screen end of screen 2003.
call selection-screen '2003'.
once this was triggered after entering vales it return to the next step then
call screen 2004.
then it goes to PBO and PAI events.
endif.
all these are done in initial screen PBO . and those are created dynamically now i want to do validations on selection-screen fields. we can;t use at selection-screen in module end end module .
plz let me know if you know any thing more.

At Selection screen validation

Hi All,
I Have a Situation, If User does not enter any thing on seelction screen my report still displays the data based on the selection criteria, what validation can be done at seelction screen to resolve this issue.
Regards,
VB

put your cursor on Selection-screen and press ABAP help...
or, use the appropriate program event, in this case: AT SELECTION-SCREEN [for screen-name is an addition].
If structure SSCRFIELDS-UCOMM eq 'SJOB' or 'PRIN' or 'ONLI', the user has selected an execution mode and you can enforce entry of something into your ranges tables (SELECT-OPTION creates a table of the same name).
In cases like this, please search forum and/or utilize SAP's excellent ABAP HELP capability.
