Hi,
In my WD application selection screen I am using a parameter(COSP-VERSN)
When i read this using read context i am getting an error saying "Could not find attribute KOKRS"
In context I have created a node with COSP-VERSN. My Kokrs will be contstant everytime.
For getting my version I need to pass KOKRS values.How can overcome this issue?
Here is the read context for versn which I have created in context Create-> NODE Option
DATA lo_nd_pversn TYPE REF TO if_wd_context_node.
 DATA lo_el_pversn TYPE REF TO if_wd_context_element.
 DATA ls_pversn TYPE wd_this->element_pversn.

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.

Hi All,

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

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.

Getting parameter id in the selection screen parameter

Hi,
There are few fields in my selection screen. I need to set the parameter id of warehouse number such that the value in the user profile should get displayed by default when the user executes the report.. The parameter id is /scwm/lgn . How do I get it? Please advise.
I have my parameter as follows:
parameter: p_lgnum TYPE /sapapo/matio_wm-lgnum obligatory.
Moderator message: please read F1-help for "parameters", section "value options".

not enough research..
Parameter: p_lgnum TYPE /sapapo/matio_wm-lgnum MEMORY ID /scwm/lgn .

To fill selection screen parameter with user's parameter id

Hi,
I need to display PLANT on the selection screen of a report as SELECT-OPTIONS.
When launching the transaction for the report, the program must fill the PLANT by default with the user's own parameter id (WRK) .
How can it be done?
Regards
Nishant

HI nishant,
in INITIALIZATION EVENT.
1. first get the parameter id value
in some variable of type plant.
(eg p1)
2. then (suppose the select option name is myplant)
MYPLANT-SIGN = 'I'.
MYPLANT-OPTION = 'EQ'.
MYPLANT-LOW = p1 . "<---- from above variable in point 1
APPEND MYPLANT.

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.
message e001.
endif.
Let me know if you still have any issue.

Dynamic selection screen parameter

Hello All,
I am facing problem in dynamic parameter declaration in selection screen. My requirement is as below,
Want to have 2 parameters in selection screen and based on first parameter (table fields) selected value, the second parameter (display the value of the selected table field) should display value of the selected field.
The problem is the second paramter type should be of first parameter selected field.
How to declare parameter dynamically after getting the first parameter selected field.
Thanks in Advance.
Regards,
Suganya.

hi
You may use the Runtime Type Information(RTTI)/ RTTS to get the parameter type at runtime
Process would be :

> l_var ?= cl_abap_typedescr=>describe_by_data(parameter).
