Error in cl_wd_dynamic_tool= check_mandatory_attr_on_view?

Hello,
We are using cl_wd_dynamic_tool=>check_mandatory_attr_on_view to check whether required fields are filled.
It also works fine if the property 'required' of a input field is set via implicit configuration.
But if the property 'required' of an input field is bound to the property required of respectiv context attribute and the property 'required' of this input field is set via implicit configuration, an error message is not issued although the field marked red.
At first we thought that bound properties of context attributes have priority to implicit configuration. But we do not have same problems ex. with the property 'read-only'. I suppose it is an error in cl_wd_dynamic_tool=>check_mandatory_attr_on_view. But before i put this error in SAP support portal i wanted to ask the opinion of SDN community whether someone had same problems.
Best regards,
Paul

Hi Jaddy Zhang ,
you have to call method inside the if condition
if it_messsages is initial.
wd_this->upload.
endif.
*i think my understanding about ur problem is correct.
if no , do paste your full code in the case upload.

Report Attribute Error Message

Hello Everyone,
I am trying to use the method report_attribute_error_message of if_wd_message_manager interface to display an error message if the user does not fill all the mandatory fields. My scenario is as follows:-
I have one node po_items with all the attributes (10 attributes) that I require. Among these 10 attributes I have 7 attributes as table Cell editors and 3 attributes as normal inputfields. So, when I am trying to check for madatory fields using the following code everything is fine a part from the link to the fields when someone doesn't enter any mandatory fields.
LOOP AT lt_items_elementset INTO le_items_element.
    IF ls_items_1-doc_date IS INITIAL.
      CALL METHOD lo_message_manager->report_attribute_error_message
      EXPORTING
          message_text = 'Please fill the Document Date'
          element      = le_items_element
          attribute_name = 'doc_date'.
    ENDIF.
    IF ls_items_1-doc_type IS INITIAL.
      CALL METHOD lo_message_manager->report_attribute_error_message
        EXPORTING
          message_text = 'Please fill the Document Type'
          element      = le_items_element
          attribute_name = 'doc_type'.
    ENDIF.
    IF ls_items_1-co_code IS INITIAL.
      CALL METHOD lo_message_manager->report_attribute_error_message
        EXPORTING
          message_text = 'Please fill the Company Code'
          element      = le_items_element
          attribute_name = 'co_code'.
    ENDIF.
    IF ls_items_1-cost_ctr IS INITIAL.
      CALL METHOD lo_message_manager->report_attribute_error_message
        EXPORTING
          message_text = 'Please fill the Cost Center'
          element      = le_items_element
          attribute_name = 'cost_ctr'.
    ENDIF.
    IF ls_items_1-plant IS INITIAL.
      CALL METHOD lo_message_manager->report_attribute_error_message
        EXPORTING
          message_text = 'Please fill the Plant Number'
          element      = le_items_element
          attribute_name = 'plant'.
    ENDIF.
ENDLOOP.
So when we click on the error message it takes you to the exact field where the error has occured. This is happening only for the fields in the table and it is not happening for the inputfields that are not in the table.
Can you explain of how to acheive this? I would greatly appreciate your help.

Gopal.

Hi,
If those Input fields are not part of table...then you can use the standard one.
For me Start date(BEGDA) is mandatory.
wd_comp_controller->gref_element->get_attribute(
        EXPORTING
          name = wd_assist->GC_BEGDA            "BEGDA

          value = lv_begda ).

Error message linking to field

Hi guys,
I'm trying to generate an error message that links to the field when clicked on.
My problem is this. This error message is for a dropdown list. When user choose a blank selection, it will generate the error message to "fill in the mandatory field", with the link to the dropdown box.
I tried lo_message_manager->report_attribute_error_message but it gives an error dump for null values (due to blank selection).
I have also tried cl_wd_dynamic_tool=>check_mandatory_attr_on_view. This works fine for the other inputfields, but it doesn't work for the dropdown list.
Please advise. Thank you very much.

Hi,
how is your dropdown done? by key/index?
because with an indexed one, none is selected, thus returning a dump when you try to have
an attribute error message (initial selected element).

Cancel Navigation when error

Hi everybody,
I am developing a WD with a tabstrip.
In each tab, I have a table. I need to check several conditions in the attributes on the tabs. For example end_date can´t be previous of begin_date. When the user type one of this errors. I would like to stop de navigation between tabs until the user correct it.
I have tried to use the function report_t100_message putting the parameter cancel_navigation with the value abap_true but I still navigate between tabs.
I have a similar problem with required attributes. I used the function cl_wd_dynamic_tool=>check_mandatory_attr_on_view. Empty required input fileds are mark in red but I can navigate.
Any idea?
Thankssss!

Hi Lorena.
Switching the tabs of the tabstrip is not a navigation like navigation using
outbound plugs. Use the onSelect action handler of the tab strip to check your
values of the actual tab before the switch takes place.
But you have to set the selectionChangeBehaviour to manual. In this case, if the
user selects a tab, the onSelect method is called before the new tab is set. Then
perform your check and if everything is ok you have to set the selected tab by
yourself.
Just have a look here on the :

Check_mandatory_attr_on_view bugs with subscribe_to_button_event

It seems I found I bug in web dynpro for abap.
When using the method subscribe_to_button_event in the wddoinit of a view to register your event handler for a popup window,
if you call the method cl_wd_dynamic_tool=>check_mandatory_attr_on_view on the method in the WDDOBEFOREACTION, it seems to deregister the event action, so the event handler method for the actions are not called, if I remove the call to the cl_wd_dynamic_tool=>check_mandatory_attr_on_view, it works fine!

How to set mandatory a InputField in standard Web Dynpro component?

Hi guys.
A very weird thing is happening. I am trying to validate that a non-mandatory STANDARD input field (COST_ASSIGNMENT) does not to be empty. This input field belongs to GENERAL_DATA_VIEW, FITE_VC_GENERAL_DATA WD component. The entry fields at screen belong to this GENERAL_DATA_VIEW, but navigation is allocated in buttons that belong to another component (LAYOUT_VIEW in the FITV_FPM WD component). All the views and components are standard and they seem to be in the same screen from user's point of view. I was able to put my own code at WDDOAFTERACTION method in LAYOUT_VIEW to raise an error message.
Incredibly, my error text message appears in the MESSAGEAREA, and the UI components from GENERAL_DATA_VIEW are rightly still in the screen waiting for user answer since I set CANCEL_NAVIGATION = 'X', but the UI components from LAYOUT_VIEW (the buttons with navigate functions) changed like they had accepted my entry in spite of I set the code in this view. In fact, below my error text displayed, there is other (success) text which communicates "Standing approval for business trips exists" with a green tick.
The success text should not be displayed since I raised an error message, even after (I think so) the system created the success message. I suspect that the standard positive message with the green tick indicates that my error is being taking into acccount by the system to be displayed but the LAYOUT_VIEW UI components dont stop navigation and the data is wrongly saved from the code where the success message was generated.
I think there would be another way to define an standard inputfield mandatory, but I dont know how to do it. Do you know that? I really appreciate all help. Thanks

hi,
just make the input feild as mandatory in properties and use the following code.
data:
lo_view_controller type ref to if_wd_view_controller,
lo_dyn type ref to cl_wd_dynamic_tool.
Create Object
create object lo_dyn.
data lt_messages type lo_dyn->t_check_result_message_tab.
Get view controller reference
lo_view_controller = wd_this->wd_get_api( ).
Call Method to verify the element has the value or not
call method cl_wd_dynamic_tool=>check_mandatory_attr_on_view
exporting
view_controller = lo_view_controller
display_messages = ABAP_TRUE
importing
messages = lt_messages .
endmethod.

Table Input field validation

Hi Experts
I have an OIF Application in which I have an Input enabled table and it is mandatory to enter the date range fields. When the user clicks 'SAVE', I have to validate if the start and end dates are entered in each record, and give an error message if blank. I wanted to know if I have to loop through each record and validate manually or if there is a better way?
Thanks
Neo

Hello Neo,
you can use the utility method CL_WD_DYNAMIC_TOOL=>CHECK_MANDATORY_ATTR_ON_VIEW to check for the mandatory attributes.
For this you need to set the STATE property of the inputfield (in the table column) to REQUIRED.

Validation and displaying as log file

hi i need to do some validation! actually in my program the delivering country and the import code works as the key. so i need to check that the delivering country and the import code is present in a table t604.(i am updating data from presentation server to an internal table)
and also i need to check that whether the country of origin is in the table t005 or not.
if the validations are success then put those into a log file and dsiplay otherwise put the error record in a log file and display and also the total; no of error records and the no of records!!
can u people plss help me!!

Dear Sonia,
u can try this.
1. Make the dropdown fields mandatory( by changing 'State' property.)
2. Use the "Check_mandatory_attr_on_view " method...
Just follow the code........
data:
lo_view_controller        TYPE REF TO if_wd_view_controller,
msg_tab                     TYPE cl_wd_dynamic_tool=>t_check_result_message_tab.
lo_view_controller = wd_this->wd_get_api( ).
    cl_wd_dynamic_tool=>check_mandatory_attr_on_view(
    EXPORTING
    view_controller = lo_view_controller
    IMPORTING
    messages = msg_tab ).
Hope this will solve ur purpose. Let me know...

In PS field RESBD-GPREIS cannot be made mandatory but can in PM

The feild RESBD-GPREIS can be made mandatory in PM but it does not take effect in PS and the field is not available in PS config. I have tried
SPRO>IMG>Project Systems>Structures>Operative Structures>Networks>User interface settings --> Define field selection for networks --> Field selection :Network:Details -->
without luck. Has anyone been able to make Price mandatory for Purchasing tab in PS? We can make external processing using AFVGD-PREIS

In general in Web Dynpro ABAP, setting the required property on the UI doesn't actually do anything except visibily mark the UI element with the required symbol (the red * next to the label). Unlike classic dynpro, this property doesn't cause a runtime check to see if the field has a value or produce an error message. This must be added within the application logic. There is a helper method cl_wd_dynamic_tool=>check_mandatory_attr_on_view.
That said, I can't comment specifically about this SRM framework. It would be something application specific that sits above the WD framework. Perhaps it has this dynamic call already built in and this situation is an error. Or it could be the case that the SRM tool is just exposing all the UI element properties and you would have to use the Enhancement Framework to extend the view logic to acutally perform a mandator check.

Required Fiedls Problem

Hi all,
There is a problem with required fields. We have two systems which one's patch level is 13 and second system's patch level is 15. In test system which has patch is 13 there is no problem about required fields. But the other test system which has patch level is 15 it says always "Please complete all required fields" error. But the field is not mandatory. I change fields mandatory status dynamically. When it is mandatory I change fields attiribute to 01. And here is complete code:
DATA: l_view_controller TYPE REF TO if_wd_view_controller,
        l_messages        TYPE STANDARD TABLE OF t_check_result_message.
l_view_controller = wd_this->wd_get_api( ).
cl_wd_dynamic_tool=>check_mandatory_attr_on_view(
                       EXPORTING
                         view_controller = l_view_controller
                       IMPORTING
                         messages         = l_messages ).

I will try the note as soon as possible...

Making Page look same in All Pixels & Writing code for Submit Button.

Hello All,
How to make the page look the same in all computers even though the pixels are different?
Please help me in this regard.
More Over if I want write the code for Submit button where the code should be written.
Whether the code is different from normal ABAP coding?
Warm Regards,
SampathKumar G.

Hi Sampath,
You can trigger mandatory field checks in WDA as in R/3. For this you need to make the "state" property of your input field to "required".
In addition to this you need to call the static method check_mandatory_attr_on_view of class cl_wd_dynamic_tool. This would then automatically verify if all the mandatory fields have been filled or not. It would then populate the error messages into an internal table and display them in the view. Also the mandatory fields which haven't been filled would be highlighted with a red border. You need to put the below coding into the action up on which you want to trigger the data chesks.
data: lt_msg TYPE cl_wd_dynamic_tool=>t_check_result_message_tab,
          lo_view_controller TYPE REF TO if_wd_view_controller,
          lo_message_manager type ref to if_wd_message_manager.
lo_view_controller ?= wd_this->wd_get_api( ).
lo_message_manager = lo_view_controller->get_message_manager( ).
cl_wd_dynamic_tool=>check_mandatory_attr_on_view(
    EXPORTING
      view_controller = lo_view_controller
      display_messages = abap_true

Validation of reused component in Main component and Control the Navigation

Dear Friends
   Good morning,
   I have one question as I mention in the subject.
         How to validate the data from re-used component in the main component and based on error or not the error fire the navigation plug ?
What I am doing is, I have two components
1. Main_comp --> V_CREATE (view).
2. Ora_comp-->V_CREATE_ACCOUNT (view).
In Ora_comp I have some fields that are mandatory. plus I have 2 password fields that have to be matched with each other like ( Password and Re-Enter password).
now in the MAIN_COMP
I have the view called v_create in this view I am using method "WDDOBEFOREACTION" to validate the things. but now I am stuck here dont know how to call the wd_api of v_create_account view of Ora_comp.
if lo_action is bound.
     case lo_action->name.
         when 'TO_REV'. <--this is the next button action who will fire the navigation plug.
         I need to write something like this.
             data l_view_controller type ref to if_wd_view_controller.
             data lo_api_interfacecontroller TYPE REF TO if_wd_controller.
             *lo_api_interfacecontroller = lo_interfacecontroller->wd_get_api( ).*
             *l_view_controller = lo_api_interfacecontroller.*
             *cl_wd_dynamic_tool=>check_mandatory_attr_on_view( view_controller = l_view_controller ).*
     "some other loginc to report the non-matching passwords error using report attribute blah blah, but its okey its not a problem.
    " The proble is this
        _l_view_controller =" ? "_ <-- what should | write here to check my view's mandatory attribute of re-used components.
        _cl_wd_dynamic_tool=>check_mandatory_attr_on_view( view_controller = l_view_controller )._
Endcase.
Endif.
please help me. How I can solve this. your any help will be appreciated.
Thank you

Naeem

Hi!
   Thank you so much for your reply, well you are right theres no navigation is taking place.. actually my view (V_CREATE) of a main component is navigating to either to review form for for review the inputs or to go back to action view to select the action like create ,,
why I wanted to use that dynamic_tool into main view and play with the reused view's attributes because when user presses the back button and try to go to the action view.. v_create view will not allow him to go unless he fills all the required fields..
I wanted to over -come that.. by flush out the message area in to_action navigation part.. so I thought may be if I can do this in main view. i can remove the messages and message areas as well but I was wrong.
well will it be possible for me to know. How can We suppress the messages and go back to action view without filling the required fields.
look the design
1 Serview view ( Oracle-Unix-Active Directory) --> user have selected the Oracle
2 Action view ( all the oracle related link2action (create, delete, rename password) --user have selected the create account
3 v_create view ( Oracle_comp , unix_comp , active_dir_comp) since user have selected the oracle I will use oracle components'view... here I have the form to create the account in oracle server. this has the mandatory fields I can use the dynamic_tool to put check on mandatory attributes.
4 review view- ( Oracle_comp , unix_comp , active_dir_comp) since user have selected the oracle I will use oracle components'view..in read only.
5 submit message view.
so problem is at 3rd view... I can check the attributes from componets ... fill it and correct and go to review.
but I cant go back to action-view without filling the correct informaiton. that I wanted to solve. Suggest me is there anyway to suppress the messages and message area on to_action or anyother place to trigger the back view navigation.
I hope this reply will you to understand what I am doing
Thank you so much and Regards

Mandatory dropdown in red colour

Hi all, I need to put a dropdown in a red marked colour if the user don't select anything on it.
I have try these method:
a)   wd_this->message_manager->report_attribute_error_message(
      message_text = text
      element = wd_context_element
      attribute_name = attribute ).
b)     lo_view_controller = wd_this->wd_get_api( ).
    cl_wd_dynamic_tool=>check_mandatory_attr_on_view(
    EXPORTING
    view_controller = lo_view_controller
    IMPORTING
    messages = msg_tab ).
But the dropdown in red is never been marked.
Am I forgetting something please?
Help please.

Just thought to update that I am using a DropDownByIndex for this coding:
Suppose I have a context node by name NODE_IDX & have 2 attributes under this KEY & VALUE. I have associated a supply function POPULATE_NODE with my context node to fill it with values as how shown below:
METHOD populate_node .
* data declaration
DATA lt_node_idx TYPE wd_this->elements_node_idx.
DATA ls_node_idx LIKE LINE OF lt_node_idx.
DATA lv_str TYPE string.

I have bound the "texts" property of my DropDown to the attribute "Value" & I have changed the "state" property to "Required".
I also put the below coding within my WDDOAFTERACTION method to trigger error messages for any mandatory fields which the user hasn't filled out.
METHOD wddoafteraction .
DATA: lt_msg TYPE cl_wd_dynamic_tool=>t_check_result_message_tab,
        lo_view_controller TYPE REF TO if_wd_view_controller.
DATA lo_message_manager    TYPE REF TO if_wd_message_manager.
lo_view_controller ?= wd_this->wd_get_api( ).
lo_message_manager = lo_view_controller->get_message_manager( ).
lo_view_controller = wd_this->wd_get_api( ).
cl_wd_dynamic_tool=>check_mandatory_attr_on_view(
    EXPORTING
      view_controller = lo_view_controller
      display_messages = abap_true
    IMPORTING
      messages = lt_msg ).
ENDMETHOD.
