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.

SELECT OPTIONS IN WEB DYNPRO ABAP

Hello experts, im working with select options in a WEB Dynpro.
There are four buttons (cancel,check,reset,copy) that apears above my select option.
My question is: There is a way to hide that buttons?
THANKS!

Sure, you can disable them using the SET_GLOBAL_OPTIONS methdo of the IF_WD_SELECT_OPTIONS class. Something like this:
wd_this->m_handler->set_global_options(
    i_display_btn_cancel = abap_false
    i_display_btn_check   = abap_false
    i_display_btn_reset   = abap_false
    i_display_btn_execute = abap_false ).

Select options in web dynpro ABAP (Event on_check)

Hi,
how can I raise a message in the event-handler method on check for a specifc field out of the Select-Option.
Best regards,
Marcus

Hello,
Create a new method and call it when you want to show the message.
METHOD message_handling .
DATA:
    lr_current_controller TYPE REF TO if_wd_controller,
    lr_message_manager    TYPE REF TO if_wd_message_manager.
lr_current_controller ?= wd_this->wd_get_api( ).
lr_message_manager = lr_current_controller->get_message_manager( ).
lr_message_manager->report_t100_message(
    msgid = iv_msgid
    msgno = iv_msgno
    msgty = iv_msgty
    p1    = iv_p1
    p2    = iv_p2
    p3    = iv_p3
    p4    = iv_p4 ).
ENDMETHOD.
In this method, the program show a message that is declared in a mesasge class. If you look at IF_WD_MESSAGE_MANAGER there are other methods to show a message.

code snap ->
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 = 'S_CARR_ID' ).
add a new field to the selection
wd_this->m_handler->add_selection_field(
                 i_id = 'S_CARR_ID'
                 it_result = lt_range_table

hi kailash,
check wheteher the field u r refering is having search help.
    if it has then set the additional parameters in method add_selection_field
I_VALUE_HELP_STRUCTURE = 'VBC07'(name of the table)                                                   I_VALUE_HELP_STRUCTURE_FIELD = 'FKART'( field name)
ex:
wd_this->go_select_options1->add_selection_field( i_id = 'FKART'
                                                   I_WITHIN_BLOCK = 'BLOCK1'
                                                   I_VALUE_HELP_STRUCTURE = 'VBCO7'
                                                   I_VALUE_HELP_STRUCTURE_FIELD = 'FKART'
                                                   it_result = lo_range_table

Theming Options for Web Dynpro ABAP/Java - Custom CSS

What options are available for creating a custom CSS for WDA? My project is going towards SAPUI5, and they want to apply the same look and feeavl to their Web Dynpro applications.
I know the Theme Designer is an option - but this customer is running on NW 7.3. Obviously to get the WD CSS to look similar UI5, it will require changing all of the WD selectors.
Finally, we have a 7.4 Sandbox. If I build the theme there, is it backwards compatible to their 7.3 landscape?

UI Theme Designer is the only supported way and it is available for NW 7.3 as well, assuming you are up to date on Support Packages. As long as you create a theme with UI Theme Designer the theme will work in any system that supports the same, there might be small functional and visual differences though depending on the SP levels of the source and target systems. SAP recommendation is to always use the latest version available to create (and consume) themes. You could start by using the Cloud version of UI Theme Designer, export and import into your own system. That said your NW 7.3 system needs to support UI Theme Designer to be able to use custom themes created by it.

Row selection in Table (Web Dynpro Abap)

Hello,
I have 2 views in my web dynpro component.
In first view , i am taking carrid and on click of submit button , i am displaying connid,fldate,currency,planetype,seatsmax in second view.
I have one button on second view to go back to fist screen.
Now, My question is :
if i select a one row of table , i want to dispaly deatils of that row in first view.
How can i do this?
Please help.

The second part of the requirement is not clear on where woudl you click and where shoudl the data be shown.
However, all this data should be ideally maintained in the component controller i.e. the c.controller should have the conterxts and map relevant nodes to the appropriate views.
Now, all the data is in c.controller which can be accessed from any view within the component. This way you can show any data in contexts in preferred view.

Problem in getting parameter value from selection screen in web dynpro abap

Hi,
I am facing problem in getting parameter value from selection screen.
Please find my code below:
DATA LT_PAR_ITEM TYPE IF_WD_SELECT_OPTIONS=>TT_SELECTION_SCREEN_ITEM.
FIELD-SYMBOLS:<FS_PAR_ITEM> LIKE LINE OF LT_PAR_ITEM,
                             <FS_OBJ_USAGE>    TYPE REF TO data.
WD_THIS->M_HANDLER->GET_PARAMETER_FIELDS( IMPORTING ET_FIELDS = LT_PAR_ITEM ).
LOOP AT LT_PAR_ITEM ASSIGNING <FS_PAR_ITEM>.
    CASE <FS_PAR_ITEM>-M_ID.
      WHEN `OBJ_USAGE`.
         ASSIGN <FS_PAR_ITEM>-M_VALUE->* TO <FS_OBJ_USAGE>.
[ Here, sy-subrc is 4, <FS_OBJ_USAGE> is not assigning.]
    ENDCASE.
ENDLOOP.
So, can any one solve this problem.
Thanks in advance,
Radhika

Hi Radhika,
Try using GET_RANGE_TABLE_OF_SEL_FIELD...
Please Refer below code..
   DATA: NODE_FLIGHTS TYPE REF TO IF_WD_CONTEXT_NODE.
DATA: RT_CARRID TYPE REF TO DATA.
DATA: ISFLIGHT TYPE TABLE OF SFLIGHT.
DATA: WSFLIGHT TYPE SFLIGHT.
FIELD-SYMBOLS: <FS_CARRID> TYPE TABLE.
Retrieve the data from the select option
RT_CARRID = WD_THIS->M_HANDLER->GET_RANGE_TABLE_OF_SEL_FIELD( I_ID = 'S_CARR_ID' ).
Assign it to a field symbol
ASSIGN RT_CARRID->* TO <FS_CARRID>.
CLEAR ISFLIGHT. REFRESH ISFLIGHT.
SELECT * INTO CORRESPONDING FIELDS OF TABLE ISFLIGHT FROM SFLIGHT
                       WHERE CARRID IN <FS_CARRID>.
NODE_FLIGHTS = WD_CONTEXT->GET_CHILD_NODE( NAME = `FLIGHTS` ).
NODE_FLIGHTS->BIND_ELEMENTS( ISFLIGHT ).
Thanks,

Select Options in Web dynpro

Hi,
I have a report, this has select options for users to enter the selection criteria. On the screen users can see 'Cancel', 'Check', 'Reset' and 'Copy' buttons but NO 'SAVE'!!!
Is there a way to save the selection made by the user as a variant? by doing this users can just select their Variant and execute the report.
Thank you,
Renu

Short answer - yes. You can of course build something application specific to save the select-option values, but there is nothing like the variant supplied by the framework.
Using personalization you can save single input values as favorites (right mouse click on a field and choose User Settings->Use Current Value as Default. However this isn't really like the old style variant, no does it capture complex values like those that can be represented within a select-option.

Data validation for Date Field in Web Dynpro ABAP

Hi ,
In my WDA i want to perform data validation for date filed. (i.e. While creating a new record i have to check the Start Date should be always lesser than End Date.)
If u ll enter the wrong date it should validate the Date and throw an error message.
Please Reply soon its urgent.
Thanks,
Deepika

Hi,
First read the two attributes start date and end date.
Then write the following condition.
IF item_start_date > item_end_date.
Error message.
Endif.
For pop up error message you need to use Create_window method of the Interface if_wd_window.
Thanks.

Validation of an inputfield in Web Dynpro ABAP

Hello together,
I have an input field in which is bound to a context. The context has a value-help.
My problem is that the user can input into tte inputfield any value. Is there a method or something to validate against values of the value-help.
Greetings,
Florian

Hi
To the best of my knowledge
as the UI element is bound to a contex you can get it back in the program using GET_ATTRIBUTE method or GET_STATIC_ATTRIBUTE
as the value is available you can validate it against any table or in whichever manner you want

Web Dynpro Abap: Select-Options: Save Selection Data

Hello,
I am using select-options in web dynpro abap. Need to add a feature where the user can save his selection values as a variant.
All I can think of is getting all the selection values and saving these into a Z table.
Can you suggest a better way?
Thank you.
Irene

Hi Irene,
Alas, it's currently not possible. You could write your own wrapper though adding a save button. Inside of the action handler you could retrieve the range tables of all fields, convert their content to a structure you like and save it a fitting db table. My suggestion is to use XML and a DB table with a XSTRING field in the data section to store the range table values.
Using personalization will allow you to customize your ui and to hide certain select option fields.
Best regards,
Thomas

How to do the feild validations in web dynpro abap

dear all,
how to do the feild validations for the screen in web dynpro abap.
thanks,
jyothi.

hi jyothi,
There are diffrent ways of doing validations for fields of screen in webdynpro abap depending on the requirements.
I am giving simplest way of doing this validation(it may fullfil your requirement also)
For e.g you want that without entering value in particular field user should not proceed to submit the data in screen.
DATA lo_message_manager    TYPE REF TO if_wd_message_manager.
DATA lo_api_controller     TYPE REF TO if_wd_controller.
lo_api_controller ?= wd_this->wd_get_api( ).
lo_message_manager = lo_api_controller->get_message_manager( ).
DATA var1 type string.
DATA: node TYPE REF TO if_wd_context_node.
node = wd_context->get_child_node( 'DATA' ).
node->get_attribute( EXPORTING name = ' VALUE'
                         IMPORTING value =     var1 ).
IF var1 IS INITIAL.
    CALL METHOD lo_message_manager->report_error_message
      EXPORTING
        message_text = 'Please enter the value'.
      EXIT.
ENDIF.
Now in above code VALUE is the attribute with whome your input field is bound .So if user doesnt enter any value into it he will get above msg (u have to use message are ui element to use this method)
If you have any other doubt feel free to ask.
regards
Panky

Web Dynpro ABAP - Select Option and ALV Component Usage

Hi,
I'm new in ABAP Web Dynpro and i was trying to follow the SDN tutorial
Web Dynpro ABAP - Select Option and ALV Component Usage
In this video, we create a new Web Dynpro ABAP component that uses both Select Options and ALV. Developers can learn the basic mechanisms for working with both of these reusable components.
Following the link: https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/media/uuid/39c54fe7-0b01-0010-0eb6-d63ac2bdd637
I implemented and generated the web dynpro with success but when i execute a test i get a dump on select-option definition.
Note
The following error text was processed in the system ECD : Exception condition "TYPE_NOT_FOUND" raised.
The error occurred on the application server ITAWSECCS01D_ECD_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
I went in debug and the piece of code dumping is:
lt_range_table =
wd_this->m_handler->create_range_table( i_typename = 'S_PROJ' ).
Is there someone who can help me?
Thanks in advance,
