WD_CPUSE_SELECT_OPTIONS( )

can u please tell me what is the use of WD_CPUSE_SELECT_OPTIONS( )

Ravi,
whenever we reuse other stnadard components ( like slav_wd_table, wdr_Select_option ) into your component,, we will declare them under used components..
In order to use that component in coding, first we have to take the reference of that component.,,,that can be done by below statemetent
DATA lo_cmp_usage TYPE REF TO if_wd_component_usage.
lo_cmp_usage = wd_this->wd_cpuse_select_options( ).

Select-options for input field

hi,
Is it possible to use 'Select-options' in web dynpro for the input field like we use in abap?
Ex. material is the input field. i want to select range also for this input field using 'Select-options'
I have tried only with ovs(f4 help) for the input field. can u pls tel me how to use if it is possible ?
Thanks,
Aishwarya.

Select-options for date field.

Hi all,
i need to give select options for Date field.How can i give that.
Thanks & Regards
Ravi.

Hi Ravi,
Use the Component WDR_SELECT_OPTIONS to include select options in Web Dynpro ABAP. Follow these steps:
1. In your Component , "Used Componet" tab add Component WDR_SELECT_OPTIONS . Component Use can be any name that you want to give, eg SELECT_OPTIONS
2. Go to the View where you want to include the Date Select Options. I am assuming that you already have an Attribute of Type DATS in your context.
3. View: Properties Tab:Create Controller Usage and select
SELECT_OPTIONS     WDR_SELECT_OPTIONS
SELECT_OPTIONS     WDR_SELECT_OPTIONS     INTERFACECONTROLLER
4. View Layout Tab:Include a View Container. In this view container we will show the Date Select Options.
5. View Attributes Tab: Create Following two attributes:
M_HANDLER type IF_WD_SELECT_OPTIONS
M_WD_SELECT_OPTIONS type IWCI_WDR_SELECT_OPTIONS
6: View Methods Tab: Create a method eg CREATE_SELECTION_SCREEN. Call this method in the WDDOINIT of the view.

When do I need to declare multiple usages of the same component

I have a noddy WD4A component with a main view containing only ViewContainerUI elements. Each container has a sub-view embedded implementing some functionality I am playing with. One of these views implements a select option by using the WDR_SELECT_OPTIONS component. I have got this working. Then I decide to make a copy of the view in order to test some modifications. I embed this in a new ViewContainerUI element on the main view.
So now I have 2 sub views implementing the same select option. When I run it, the 2nd select option appears in the first view as a duplicate. The only way I can fix this is by declaring a second usage (of WDR_SELECT_OPTIONS) in the component and using this in the copied view.
So now I have 2 WDR_SELECT_OPTIONS component usages declared (with different names) so that my 2 views can coexist on the screen. Is this really necessary? Had it been the same view implementing both select options fair enough - but these are 2 different views.
If the views were not displayed at the same time, could I have declared and used just 1 component usage?
Peter

I have still not succeeded in dynamically creating a 2nd select Option and getting it to display in a View Container (called VC_SOD). The code compiles and runs but the select option does not display. This is hopefully something I will never need to do in reality. Just an exercise.
The code that is commented out is the original standard technique of using a select_option usage. There is probably more then 1 fundamental mistake in the code

Wdr:select_options and highlight Error Message with a Link to Inputfield

Hi,
I have created a InputField on a View using WDR_SELECT_OPTIONS. I want to validate this Input Field and give
Error Message, when User fill it with wrong Values. How can we achieve this and important is to mark it on Screen WITH a RED STAR. ( e.g. highlighted )
Thanks!
Best Regards
Beserithan Malabakan

I've not tried it with select options before, but you might wan to have a look at setting the REPORT_ATTRIBUTE_ERROR_MESSAGE method of the message object. This way the message gets attached to any UI element bound to the context attribute you issue the message for. But as I type this and think about it some more; I see where the problem lies. The Select Options component doesn't follow an approach of cross component context binding. It dynamically generates its own context.
If I had a little more time I would test this out; but it might be worth your while to research. When you initialize the Select-Options, you normally get access to the interface controller:
data: l_ref_cmp_usage type ref to if_wd_component_usage.
l_ref_cmp_usage =   wd_this->wd_cpuse_select_options( ).
if l_ref_cmp_usage->has_active_component( ) is initial.
    l_ref_cmp_usage->create_component( ).
endif.
* get a pointer to the interface controller of the select options
*component
wd_this->lv_wd_select_options =
       wd_this->wd_cpifc_select_options( ).
* init the select screen
wd_this->lv_sel_handler =
       wd_this->lv_wd_select_options->init_selection_screen( ).
This interface controller (LV_WD_SELECT_OPTIONS in my case). Has a GET_API method that returns the component controller. In turn you might be able to access the context of the Select-Options directly. Its a crazy idea, but worth a try.

Access via 'NULL' object reference not possible   - GET_RANGE_TABLE_OF_SEL_

Hi Guru's,
   i am new for WebDynpro programming.I am trying to use select-options tutorial.
System showing select options and table binding on screen when i test the application.
I have using search button to get the value which user will i/p.for that onaction method created, i have writen the code to get the values which user will input.
Method given below is of componentcontroler
method wddoinit .

hi ,
The attribute M_HANDLER is an attirbute of component controller (as told by your post) and so you cannot access it as you have done it.
You will have to access it as .
WD_COMP_CONTROLLER->M_HANDLER->GET_RANGE_TABLE_OF_SEL_FIELD(I_ID = 'S_CARR_ID' ).
Try doing it.
Or else , if you have created a similar attribute in your view itself , then it is "INITIAL" and hence you are getting the dump.
You will have to assign the view attribute "M_HANDLER" with the value of your component controller attribute "M_HANDLER" ,because all the initializations are done in WDDOINIT of comp controller and on component controller atribute "M_HANDLER".
Thanks,
aditya.

Select-options in Selection Screen to show more rows for entering values

Hi all,
In my webdynpro abap I have added the SELECT-OPTIONS componenet and working fine.
User need in the Selection Screen for select options more rows to show entering values in single time.
THe Default Rows show only 5 .
user need to change to 10 or 15 Rows to show.
Pl help .
THanks in advance.

Hi,
Here is the way which I just tested and found working.
This is the main code which needs to be written.
TYPES:
    ty_r_vbeln TYPE RANGE OF vbeln,
    ty_s_vbeln TYPE LINE OF ty_r_vbeln.

ASSIGN lt_range->* TO <fs_range>.
do 10 times.
APPEND ls_vbeln TO <fs_range>.
enddo.
For further refinement, you can create a input field in view for number of lines to be shown as enabled.
The complete code is as below.

I can see the tray in the view cannot see any field (expectation was to see a select-option for BUKRS.
Any hints? Am i missing something. I have followed the tutorial for select options in webdynpro abap.

Hi Sascha,
No i cannot see the buttons either.
Following is how the view is embedded.

WD -Select options - DUMP -Practicing Rich heilman's app

Hi,
I am practising the tutorial created by Rich heilman /people/rich.heilman2/blog/2005/12/20/using-select-options-in-a-web-dynproabap-application
I am getting following dump while running i browser.
Error when processing your request
What has happened?
The URL http://ssss.com/sap/bc/webdynpro/sap/ytest/ was not called due to an error.
Note
The following error text was processed in the system DV1 : Exception condition "TYPE_NOT_FOUND" raised.
The error occurred on the application server sape-dev_DV1_00 and in the work process 0 .
The termination type was: RABAX_STATE
The ABAP call stack was:
Method: DESCRIBE_BY_NAME of program CL_ABAP_TYPEDESCR=============CP
What can I do?
If the termination type was RABAX_STATE, then you can find more information on the cause of the termination in the system DV1 in transaction ST22.
If the termination type was ABORT_MESSAGE_STATE, then you can find more information on the cause of the termination on the application server sape-dev_DV1_00 in transaction SM21.
If the termination type was ERROR_MESSAGE_STATE, then you can search for more information in the trace file for the work process 0 in transaction ST11 on the application server sape-dev_DV1_00 . In some situations, you may also need to analyze the trace files of other work processes.
If you do not yet have a user ID, contact your system administrator.

All I did is i used a different table and follwed all steps.

Disable the Select-options field in the viewcontainer

Hi,
I have two select option fields(Date,Number) in a viewcontainer .
Now i need to disable one of the select-option field(Date) in the view container based on the condition.If I give Enability for the view container then both the select options will get diasbled.Is there any way to disable only Date select-option field in the view container.
Thanks in Advance.

Hi,
I just tested this solution and it is working for me....Following on Thomas's suggestion...I did the following....
I just had one select-option on my scr...but it can be done with two too...
step1:
created three attributes at component level under the attribute tab ( as suggested by Thomas )
ENABLE_PRI_SELECTOPTION type WDY_BOOLEAN
M_HANDLER type ref to     IF_WD_SELECT_OPTIONS
M_WD_SELECT_OPTIONS type ref to     IWCI_WDR_SELECT_OPTIONS
Note: all are with public check box checked....so that all your views can see these attributes
I created a method at componenet controller leverl: create_select_option....in this method i have following code:
DATA:
lt_range_table TYPE REF TO data,
* rt_range_table TYPE REF TO data,
read_only TYPE abap_bool,
typename TYPE string.
DATA:
lr_componentcontroller TYPE REF TO ig_componentcontroller,
l_ref_cmp_usage TYPE REF TO if_wd_component_usage.
* create the used component
l_ref_cmp_usage = wd_this->wd_cpuse_select_options( ).
IF l_ref_cmp_usage->has_active_component( ) IS INITIAL.
    l_ref_cmp_usage->create_component( ).
ENDIF.
* get a pointer to the interface controller of the select options
*component
wd_this->m_wd_select_options = wd_this->wd_cpifc_select_options( ).
* init the select screen
wd_this->m_handler = wd_this->m_wd_select_options->init_selection_screen( ).
* create a range table that consists of this new data element
lt_range_table = wd_this->m_handler->create_range_table(
i_typename = 'PERSNO' ).
* add a new field to the selection
wd_this->m_handler->add_selection_field(
i_id = 'PERSNO'
I_VALUE_HELP_TYPE = if_wd_value_help_handler=>CO_PREFIX_SEARCHHELP
I_VALUE_HELP_ID = 'ZHELP_WDA_PERNR'
I_NO_INTERVALS = abap_true
it_result = lt_range_table
i_read_only = wd_this->ENABLE_PRI_SELECTOPTION ).   <-----pls see here how i am controlling the read only property
I assume you know this much...already....but i am just putting everything down....
step2:
in my view where i want to display the select-options....i added this code under my wddoinit method
DATA lo_componentcontroller TYPE REF TO ig_componentcontroller .
lo_componentcontroller =   wd_this->get_componentcontroller_ctr( ).
lo_componentcontroller->ENABLE_PRI_SELECTOPTION = abap_false.    <--pls see initially we want this field to be open
lo_componentcontroller->create_select_option(
step3:
i did not have much logic to control the select option field so i added a button which if user presses the field become disable...
under that button action method i added the following code:
DATA lo_componentcontroller TYPE REF TO ig_componentcontroller .
lo_componentcontroller =   wd_this->get_componentcontroller_ctr( ).
lo_componentcontroller->ENABLE_PRI_SELECTOPTION = abap_true.
   "<---pls see here how i am changing the global *attribute which Thomas has suggested for controlling the "read only" attibute for the select-option field....you can put this under *your "if" statement....
"this step is very important if you do not remove the field you will get the dump...since it will try to add the same field again
"which produces dump from system....
lo_componentcontroller->m_handler->REMOVE_SELECTION_SCREEN_ITEM(
i_id = 'PERSNO' ).
"now call the same method which we created at component level to create the select_options...
lo_componentcontroller->create_select_option(
that is all....it works great for me.....let us know if still have any questions....
Thanks...

How to hide default buttons on WD selection screen

Hi Experts,
Is there a way to hide default buttons ( Cancel, Check, Reset, Copy ) on web dynpro selection screen ??
Please let me know how can I achieve this..
Thanks in advance !

By selection screen do you mean the select-options reusable component? If so, then there is an API of the component that you can call to disable these fields. Use the SET_GLOBAL_OPTIONS method of the select-options API to acomplish this:
data: l_ref_cmp_usage type ref to if_wd_component_usage.
l_ref_cmp_usage =   wd_this->wd_cpuse_select_options( ).
if l_ref_cmp_usage->has_active_component( ) is initial.
    l_ref_cmp_usage->create_component( ).
endif.
wd_this->lv_wd_select_options =
       wd_this->wd_cpifc_select_options( ).
* init the select screen
wd_this->lv_sel_handler =
       wd_this->lv_wd_select_options->init_selection_screen( ).
wd_this->lv_sel_handler->set_global_options(
    EXPORTING
*      i_display_btn_cancel = ABAP_TRUE    " Displays "Cancel" Button
*      i_display_btn_check   = ABAP_TRUE    " Displays "Check" Button
*      i_display_btn_reset   = ABAP_TRUE    " Displays "Reset" Button
      i_display_btn_execute = abap_false    " Displays "Apply" Button

Problem in select-options

I am not able to see my view element container containing my select options in the webpage although it shows in my view.
The code used by me in the doinit method is
METHOD wddoinit .
DATA lo_cmp_usage TYPE REF TO if_wd_component_usage.
lo_cmp_usage =   wd_this->wd_cpuse_select_options( ).
IF lo_cmp_usage->has_active_component( ) IS INITIAL.
    lo_cmp_usage->create_component( ).
ENDIF.
DATA lo_interfacecontroller TYPE REF TO iwci_wdr_select_options .
lo_interfacecontroller =   wd_this->wd_cpifc_select_options( ).
    DATA lo_r_helper_class TYPE REF TO if_wd_select_options.
    lo_r_helper_class = lo_interfacecontroller->init_selection_screen(
DATA lo_r_helperclass TYPE REF TO if_wd_select_options.
lo_r_helperclass = lo_interfacecontroller->init_selection_screen(
DATA lt_range TYPE REF TO data.
CALL METHOD lo_r_helperclass->create_range_table
    EXPORTING
      i_typename     = 'VBELN'
    RECEIVING
      rt_range_table = lt_range.
CALL METHOD lo_r_helperclass->set_global_options
EXPORTING
    i_display_btn_cancel = ABAP_FALSE
    i_display_btn_check   = ABAP_FALSE
   i_display_btn_reset   = ABAP_FALSE
    i_display_btn_execute = ABAP_FALSE.
CALL METHOD lo_r_helperclass->add_selection_field
    EXPORTING
      i_id              = 'VBELN'
      it_result         = lt_range
      i_obligatory      = abap_true
      i_value_help_type = if_wd_value_help_handler=>co_prefix_none
      i_value_help_id   = 'VMVA'.
ENDMETHOD.

How to create select options

Hi,
Please guide me to implement select options in webdynpro.
Regards,
Ratheesh BS

Hi Ratheesh,
Sorry for the late reply. The m_handler is just a normal reference variable of type if_wd_select_options. Within the WDDOINIT methos you would be calling the interface controller method init_selection_screen to get the helper class. You just need to use this reference for calling the method set_global_options with your desired criteria. Just try go through the sample code fragment below:
METHOD wddoinit .
DATA: lr_select_options TYPE REF TO iwci_wdr_select_options.
DATA lr_helper TYPE REF TO if_wd_select_options.
DATA: lt_range TYPE REF TO data.
DATA: lr_comp_usage TYPE REF TO if_wd_component_usage.
" This code is to instantiate the component WDR_SELECT_OPTIONS
lr_comp_usage = wd_this->wd_cpuse_select_options( ).
IF lr_comp_usage->has_active_component( ) IS INITIAL.
    lr_comp_usage->create_component( ).
ENDIF.
" call the interface controller method init_selection_screen to get the helper class
lr_select_options = wd_this->wd_cpifc_select_options( ).
" You are getting the necessary reference to the component into lr_helper here
lr_helper = lr_select_options->init_selection_screen( ).
" Use the helper class to create a range table for the data element S_CARR_ID
lt_range = lr_helper->create_range_table( i_typename = 'S_CARR_ID' ).
" Add a Selection Screen Field
lr_helper->add_selection_field( i_id   = 'S_CARR_ID'
                               it_result = lt_range ).
" Removing the Cancel button from the toolbar displayed
lr_helper->set_global_options( i_display_btn_cancel = abap_false
                                  i_display_btn_check   = abap_true
                                  i_display_btn_reset   = abap_true
                                  i_display_btn_execute = abap_true ).
ENDMETHOD.
Hope this helps resolve your problem.
