How to show error message when all inputfields are not filled

[Former Member]

H Experts,

I have created one Webdynpro application..in that if we are not filling all  input field  it should show the error that " fill all the require fields" like ALV report..but it is giving dump..

Please share your knowledge..

find the attachment..

Thanks

Hi Abhay,

You need to mark the input fields as "REQUIRED" and use the method  CL_WD_DYNAMIC_TOOL=>CHECK_MANDATORY_ATTR_ON_VIEW to show errors if the required fields are not filled

Note: this method reports attribute error messages of individual input fields.

If you need to show only one message instead of individual messages , you can do it by just receiving error messages from above method and prepare an error message and use message manager method REPORT_ERROR_MESSAGE( ).

Hope this helps you.

Hi Abhay,

You can achieve your requirement as below

• Go to view layout and find out the view element and set the property "state" to required as below

• Go to the methods tab and add the below code in method WDDOBEFORE ACTION.

METHOD wddobeforeaction .
  DATA lo_api_controller TYPE REF TO if_wd_view_controller.
  DATA lo_action         TYPE REF TO if_wd_action.

  lo_api_controller = wd_this->wd_get_api( ).
  lo_action = lo_api_controller->get_current_action( ).

  IF lo_action IS BOUND.
    CASE lo_action->name.
      WHEN 'SAVE'. "Replace this with your action name
        cl_wd_dynamic_tool=>check_mandatory_attr_on_view(
          EXPORTING
            view_controller  =     lo_api_controller
            display_messages = abap_true
        ).
    ENDCASE.
  ENDIF.
ENDMETHOD.

Hope this helps you.

Hi Abhay,

You can perform additional validations against data consistency as below

  DATA lo_api_controller TYPE REF TO if_wd_view_controller.
  DATA lo_action         TYPE REF TO if_wd_action.
  DATA lt_messages  TYPE
cl_wd_dynamic_tool=>t_check_result_message_tab.
  DATA ls_messages  TYPE cl_wd_dynamic_tool=>t_check_result_message.
  lo_api_controller = wd_this->wd_get_api( ).
  lo_action = lo_api_controller->get_current_action( ).
  IF lo_action IS BOUND.
    CASE lo_action->name.
      WHEN 'OPEN_RM'.
        cl_wd_dynamic_tool=>check_mandatory_attr_on_view(
          EXPORTING
            view_controller  =     lo_api_controller
            display_messages = abap_false
          IMPORTING
            messages         = lt_messages
        ).
        " all required fields are filled and hence no errors from
        " mandatory check
        IF lt_messages[] IS INITIAL.
          " read the context node of your input
            DATA lo_nd_date TYPE REF TO if_wd_context_node.
            DATA lo_el_date TYPE REF TO if_wd_context_element.
            DATA ls_date TYPE wd_this->element_date.
*           navigate from <CONTEXT> to <DATE> via lead selection
            lo_nd_date = 
  wd_context->get_child_node( name = wd_this->wdctx_date ).

*           get element via lead selection
            lo_el_date = lo_nd_date->get_element( ).
*           @TODO handle not set lead selection
            IF lo_el_date IS INITIAL.
            ENDIF.
*           get all declared attributes
            lo_el_date->get_static_attributes(
              IMPORTING
                static_attributes = ls_date ).

          IF ls_date-begda < '20140101'.

            "rais error message
*             get message manager
            DATA lo_api_controller     TYPE REF TO if_wd_controller.
            DATA lo_message_manager    TYPE REF TO if_wd_message_manager.
            lo_api_controller ?= wd_this->wd_get_api( ).
            CALL METHOD lo_api_controller->get_message_manager
              RECEIVING
                message_manager = lo_message_manager
                .
            
            data lv_text TYPE string.
            lv_text = 'Start date should be after 01.01.2014'.
            
*             report message
            CALL METHOD lo_message_manager->report_attribute_error_message
              EXPORTING
                message_text              = lv_text
                element                   = lo_el_date
                attribute_name            = 'BEGDA'
                .
          ENDIF.
        ENDIF.
    ENDCASE.
  ENDIF.

Note: above code performs additional check on BEGDA

Hope this helps you.

Hi Abhay

If ls_node_selection-status is NOT INITIAL.

    lo_el_node_selection->get_attribute(

                 Exporting

                   name = 'division'

                  IMPORTING

                    value  = lt_division ).

If lt_division is INITIAL

message 'please provide input'

Elseif

Read itab into wa where division = lt_division.(itab- where data of division resides)

if sy-subrc = 0.

elseif

message ' please provide correct data'.

endif

thanks

Hi,

This code provided by you ..this also I have to write in" WDDOBEFORE ACTION "method?

becoz it is not working

Thanks

Abhay.

[ramakrishnappa · Accepted solution]

Yes, always validation logic goes in WDDOBEFOREACTION ( ).

Hi Ramakrishnappa Gangappa,

In my Webdynpro which created based on one GUI existing report in that input screen parameter I am able to select multiple input for the input field but in webbui in Webdynpro in that I am not able to select multiple field together how to do that?..please refer the screen shot..

Thanks

Abhay Manna.

[TudorRiscutia · Accepted solution]

Hello Abhay,

     For that, you'll have to make use of the functionality of the standard WDR_SELECT_OPTIONS component. You can find plenty tutorials about this on Google.

Tudor

[ramakrishnappa · Accepted solution]

Hi Abhay,

Hope you are using method ADD_SELECTION_FIELD( ) of IF_WD_SELECT_OPTIONS.

Make sure that the value of parameter I_NO_EXTENSION is set to ABAP_FALSE

Example:

wd_this->m_sel_options->add_selection_field(
  EXPORTING
    i_id                         = 'VBELN'
    it_result                    = LT_vbeln    " Reference to Range Table
    i_no_extension               = ABAP_FALSE    " No Multiple Selection
).

Hope this helps you.

Hi,

Waiting for some positive answer. Please advice me how to do that...

Thanks

[ramakrishnappa · Accepted solution]

Hi Abhay,

I think, I am still not getting your requirement clearly.

As per your code given, you are trying to execute the abap program with some selection parameters and get the output from memory.

Also, from your earlier screenshots, I can make out that, you are trying build the selection screen in WDA same as abap program.

i.e. Build the selection screen in Web dynpro and pass the same parameters to abap program & finally get the data from memory.

Now, are you looking for a selection screen with multiple option in WDA?

Regards,

Rama

[Former Member · Accepted solution]

Hi Rama,

Yes you are absolutely got my requirement....in WDA I have got the selection screen as I have given the screenshot...but in that I am not getting that arrow mark for selecting the multiple selection..i have indicated in screen shot...

Thanks

Abhay Manna.

[ramakrishnappa · Accepted solution]

Okay,

Hope you have developed the selection screen by using methods ADD_SELECTION_FIELD.

Then, please pass the parameter i_no_extension = abap_false.

Example:

wd_this->m_sel_options->add_selection_field(

  EXPORTING

    i_id                         = 'VBELN'

    it_result                    = LT_vbeln    " Reference to Range Table

    i_no_extension               = ABAP_FALSE    " No Multiple Selection

).

Hi Rama,

Thank you very much,As per your guidance . my problem solved now I am able to select the multiple data.

But can i create variant in Webdynpro.as like ALV report we used to create variant. and save the input parameter. is it possible to create variant in Webdynpro. if yes please share your knowledge.

Thanks

Abhay Manna

[ramakrishnappa · Accepted solution]

Hi Abhay,

By default, there is no standard functionality of variant in WDA selection screen / application but we can create variants by using our custom logic.

Hope following link might be helpful for you.

Hi Rama.

I was trying to create variant in Webdynpro. by referring your link what ever you given

But in method WDDOMODIFYVIEW  I have declare

but in that line it is showing an error

that is TYPE "ELEMENT_VARIANT_TABLE" is unknown.

could you please give me advice how to remove this error.

Thanks

[ramakrishnappa · Accepted solution]

Hi Abhay,

It is refering the context node VARIANT_TABALE.

So,create a context node VARIANT_TABLE,

Hi Rama, Hope you are doing well. I have created the variant after long try. thank for your guidance. Now I have one problem with the field length,in Webdynpro last column as per my screen shot is not giving the full length even though in structure I have created the field with 30 character but its not taking more than 10 character, but  same report in GUI coming proper can you give me some advise how to resolve this?? please find the attachment Thanks Abhay

[ramakrishnappa · Accepted solution]

Hi Abhay,

It seems that you have set the width for the column, so its not visible in the output. Try to adjust the width or don't set the width.

if you have not set the width, check by debugging whether the data of last column is filled completely.

Is alv table width set ?

Try to re-size the width of column in your screen and check if you can see missing data.

You can also try the below code to set the width of column and check if your data visible.

          WHEN 'SOURCE'.

               LS_COLUMNS-R_COLUMN->SET_WIDTH('20EX' ).

Hi, still it is not working? ??

[ramakrishnappa · Accepted solution]

Okay, Thats weird....

Are you able to see the changes to width of column "Source" in out put?

If width changes occurred and still data is missing, then data is not completed populated into internal table.

[Former Member · Accepted solution]

Hi, No I cant see the changes.. ?? length is showing only 10 character..
