Validation of SELECT OPTIONS

Hi Gurus,
Please let me know which is the best way to validate a select option and performance way also it must be best.
May be this is a silly question but still I was not able to find the best convincing answer in the FORUM.
Kindly validate.
Method 1:
AT SELECTION-SCREEN ON so_vbeln . " Delivery document
PERFORM validate_vbeln .
FORM validate_vbeln.
DATA : l_t_vbeln TYPE TABLE OF vbuk-vbeln WITH HEADER LINE ,
l_f_vbeln TYPE vbuk-vbeln .
RANGES ra_vbeln FOR vbuk-vbeln.
LOOP AT so_vbeln.
IF NOT so_vbeln-low IS INITIAL.
ra_vbeln-sign = 'I'.
ra_vbeln-option = 'EQ'.
ra_vbeln-low = so_vbeln-low.
APPEND ra_vbeln.
ENDIF.
IF NOT so_vbeln-high IS INITIAL.
ra_vbeln-sign = 'I'.
ra_vbeln-option = 'EQ'.
ra_vbeln-low = so_vbeln-high..
APPEND ra_vbeln.
ENDIF.
ENDLOOP .
IF NOT so_vbeln[] IS INITIAL.
SELECT vbeln INTO TABLE l_t_vbeln
FROM vbuk

SET CURSOR FIELD 'SO_vbeln-HIGH'.

Hello Raj,
For me if the SELECT-OPTION fetches atleast one record from the check table, processing should be allowed to proceed.
It's not required to check each & every records in the select-option & throw an error message for these invalid records (unlike PARAMETERs)
I would code something like this:
SELECT vbeln INTO TABLE l_t_vbeln UP TO 1 ROWS
FROM vbuk
WHERE vbeln IN so_vbeln. ENDSELECT.
IF sy-subrc NE 0.
MESSAGE 'No valid Sales Order selected for the input range. Please check.' TYPE 'E'.
ENDIF.

Validation of select-options in WEb DynPro ABAP

Can anyone please help me on validating select-options. I want to have a functionality like what we use in normal text field while validating the field. We generally use the REPORT_ATTRIBUTE_ERROR_MESSAGE funciton.
How can we achieve the same thing with select-options, cuz the select-options are not bound with any attribute.

Validation for Select-Option - Issue

Hi Experts!!
I have a select-option s_field on which I have written a validation under AT SELECTION-SCREEN. Now, the problem is that, if validation fails in second line of s_field, then to change it when we click on Extension, it's not allowing to enter but is throwing error message again and again as AT SELECTION-SCREEN is called.
Suppose, I have entered 2 single values as C001 and F001. s_field will have 2 entries. Now, C001 is a valid value but F001 is not. PFB my code:
LOOP AT s_field.
SELECT SINGLE *
FROM ztable INTO ls_field
WHERE field EQ s_field-low.
IF sy-subrc NE 0.
" Error Message
ENDIF.
ENDLOOP.
Now, for C001, sy-subrc will be 0. But for F001 sy-subrc is 4 and hence will throw an error. Now, to correct this, I am trying to enter into extension, but as this will be called again, I am unable to. Hope I explained it clearly.
I do not see any possibility to correct this. Can anybody please suggest if any workaround can be implemented?
Your help is highly appreciable.

Hi,
You can try the following:
AT SELECTION-SCREEN on s_field.
LOOP AT s_field.
SELECT SINGLE *
FROM ztable INTO ls_field
WHERE field EQ s_field-low.
IF sy-subrc NE 0.
MESSAGE s398(00) DISPLAY LIKE 'E' with 'ERROR MESSAGE'.
ENDIF.
ENDLOOP.
I hope this works as per your requirement.

Validation of SELECT-OPTIONS in selection screen

Hi Experts,
I need to validate the user entered values in the selection screen, specifically in SELECT-OPTIONS. So, currently am doing by checking S_VBELN-LOW and S_VBELN-HIGH.
BUt, curious that Is there any standard SAP Function module to use for this purpose? I searched in SE37 by giving OPTIONS but did not find any!!
Thank you

Hi,
Instead of searching for the function module .. use the event at selection-screen on or at selection-screen and write your validation logic only if there no value table for the particular field..
Thanks

Validation of Select Options for a field

Hi All,
I need to write a validation logic for a select option for VTWEG (Distribution Channel).
select-options: s_vtweg for komg-vtweg.
I need to check whether the user has entered the correct value based on the search help. The check table of this particular field is TVTW.
Following is the code i wrote under the AT SELECTION-SCREEN block:
IF NOT S_VTWEG-LOW IS INITIAL.
SELECT SINGLE VTWEG INTO KOMG-VTWEG FROM TVTW
                                 WHERE VTWEG IN S_VTWEG.
IF SY-SUBRC NE 0.
CONCATENATE ' Please enter the correct
                                Distribution Channel '
Z_MSG INTO Z_MSG.
SET CURSOR FIELD 'S_VTWEG-LOW'.
MESSAGE E000 WITH Z_MSG.
ENDIF.
ENDIF.
It works fine when the user enters a wrong value in the S_VTWEG-LOW field, where as if i gives more than one wrong value in the range or giving individual values its not working. Let me know how to do the validation check for multiple values entered individually or in ranges.
Could you please suggest how to resolve this problem.
Thank You,
Suresh

You could do something like this.....here looping at the select-option table and check the values for low and high.
report zrich_0003.
tables: komg.
data: z_msg(100) type c.
select-options: s_vtweg for komg-vtweg.
at selection-screen.
loop at s_vtweg.
    if not s_vtweg-low is initial.
      select single vtweg into komg-vtweg from tvtw
             where vtweg = s_vtweg-low.
      if sy-subrc ne 0.
        concatenate ' Please enter the correct
        distribution channel '
                  z_msg into z_msg.
        set cursor field 'S_VTWEG-LOW'.
        message e001(00) with z_msg.
      endif.
    endif.
    if not s_vtweg-high is initial.
      select single vtweg into komg-vtweg from tvtw
             where vtweg = s_vtweg-high.
      if sy-subrc ne 0.
        concatenate ' Please enter the correct
        distribution channel '
                  z_msg into z_msg.
        set cursor field 'S_VTWEG-HIGH'.
        message e001(00) with z_msg.
      endif.
    endif.
endloop.

Validation of select-option in module pool

Hi experts,
I want to make a check according to a field on my dynpro 100. The dynpro has a subscreen area and there is a select-option which I want to check (so_matnr).
According to the check I want to update my table control on the same dnypro.
How can I check so_matnr if it is on the subscreen?
When I'm trying to use FIELD statement it says that input/output field "so_matnr" not defined.

you need to use event at selection-screen or at selection-screen on <selectoption>
at selection-screen on s_matnr.
"here you need to place the logic.
Though it is a module pool screen. but you designed the select-options in the normal way. so for the subscreen you have to follow normal events.

Select-option validation

Hi,
Can any body tell me the best option for validating the select-option field in selection screen.
suppose i have a select option s_lifnr on selection screen.how i can validate that vendor.we have to validate the range or we have to check for at least single value..is valid..what is the best possible solution?
Thanks.

the best solution is to check if a single value is fetched from the db
at selection screen on so_lifnr
select single * from lfa1
where lifnr in so_lifnr.
if sy-subrc NE 0.
Message 'Invalid vendor' type 'E'.
endif.
The reason is simple imagine you give a range of 1 to 10 in so_lifnr, then there might be vendors only for 1, 3, 5 ,7. You dont want to give an error message in this case if there is no vendor 2,4, etc...
Also imagine that there are 10000 vendors and the range now has 1 to 10000, imagine the performance if you are to validate each value in the select option.
Last but not the leaset the user has a free option to use patterns (astericks ), signs ( E or I ) , options ( EQ, NE, GE, LE, GT, LT,BT etc ) in select options. So user may enters ABC and 'I in the sign. It would then be hard to code to find exactly all the possible entries the user wants, unless they are selected from db.
So as you can see there are a lot of possible inputs for a select option, the best approach is to validate a single value from database.

Advait

Selection-options validation

i want to do required field validation for select-options:s_slmtnr for mara-matnr.
that is whether user has entered the high and low value.
s_slmtnr-high and low show not be blank.

aswk,
thanks for the reply.
my code:
IF MA_DE = 'X'.
   IF S_MATUM-LOW = 0 OR S_MATUM-HIGH = 0.
     MESSAGE: 'PLEASE ENTER RANGE' TYPE 'E'.
   ENDIF.
ENDIF.
but here if i put 'AND' instead of 'OR'.it will not work for both low and high.
what i know is 'AND' is used to do for both true,but here 'OR' works like that why.

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'.

Event should trigger when enter is pressed on select option for validation

Hi,
I want to trigger a event when enter is pressed on a select option field for validation.
I have created a select option through coding. I am not able to find out any method or class for that.
please advice.

Hi Sachin ,
If you want ot use the methods in the class CL_WDR_SELECT_OPTIONS.
You can find here:-
[WDR_SELECT_IPTIONS|https://cw.sdn.sap.com/cw/docs/DOC-20864.pdf]
Check these if can find ur required one.
If you are using any ui element then you can use ON_ENTER event as a action as stated by Baskaran.
Check also if these threads can help you:-
[WebDynpro ABAP select options method SET_VALUE_OF_PARAMETER_FIELD;

Thanks & Regards,
