No furthur action if "check_mandatory_attr_on_view" returns error message

[pranav_nagpal2]

Hi All,

I am using this code to check the mandatory fields in my view.

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 ).

Now i want to check if mandatory fields are not filled it should not do any furthur action. Please tell how can i achieve this.

Thanks in advance.

Hi,

depending on the messages in the msgtab wecan use the method of IF_WD_MESSAGE_MANAGER.

REPORT_ERROR_MESSAGE

Please check out this sample code -

Get the attribute value of the field for wihich you are validating using the GET_ATTRIBUTE method.

We can write this code in the event hanlder or modifyview

if item_carrid is not initial.

l_current_controller ?= wd_this->wd_get_api( ).

l_message_manager = l_current_controller->get_message_manager( ).

if item_carrid is initial.

l_str = 'Please Enter The Carrier Id'.

• report message

l_message_manager->report_error_message(

message_text = l_str

• PARAMS = PARAMS

• MSG_USER_DATA = MSG_USER_DATA

• view = 'MESG'

• show_as_popup = 'X'

• IS_PERMANENT = IS_PERMANENT

• SCOPE_PERMANENT_MSG = SCOPE_PERMANENT_MSG

• CONTROLLER_PERMANENT_MSG = CONTROLLER_PERMANENT_MSG

• MSG_INDEX = MSG_INDEX

).

Hi,

Please see this code below

if MSG_TAB-T100_MESSAGE CO 'E'.

else.

DATA lo_COMPONENTCONTROLLER TYPE REF TO IG_COMPONENTCONTROLLER .

lo_COMPONENTCONTROLLER = wd_this->get_componentcontroller_ctr( ).

lo_componentcontroller->methupdate(

).

endif.

I tried the above code but it is returning an error message that since msg_tab is not a table with header line no component with name T100_MESSAGE exist.

Also i tried if msg_tab-msgty EQ 'E'. it is returning same error message.

Can you please tell what to write in IF condition.

Thanks

I have 21 fields to validate and requirement is not that big its just that if mandatory fields are not filled just display an error message and dont update data in database.

So if instead of getting all 21 attribute and thn checking for initial condition i thought if i can use this static method provided by SAP. But what it is doing is it is returning an error message but it is not stoping the data from getting updated in database.

Can you please suggest something??

Thanks.

Hi,

I have done like this -

In the View's Attributes tab I have declared the variable with TEXT as STRING.

Based on this I validated the code -

method onactionenter .
wd_this->text = 'YES'.
endmthod.

In the Modify View I have coded like this -

if wd_this->text = 'YES'.

if item_connid is initial.
       item_text1 = 'Please enter value'.
 " this is a attribute in  the Context node
    use the report_error_message
   else.
      item_text = ' '.
      lr_text->bind_text( path = 'TEXT'   ).
endif.

 wd_this->text = ' '.
  elem_context1->set_attribute(
      value  =  item_text
      name   = 'TEXT'
         ).

endif.

In this link he just used the check_mandatory_attr_on_view method when save button is pressed. What if fields are not validated that condition is not there.

Hi,

Please check the notes on this -

Note 1026272 - WDA: Mandatory check on view of multiple context nodes 
Note 1091460 - WDA: CHECK_MANDATORY_ATTR_ON_VIEW checks only LeadSelection
1228965

Or

This method is only returning the type of error the IMPORTING paramter (HAS_ERRORS) is of type Boolean right. We can only only the errors occured but not the exact error.

'X' == True '' == False for this WD_BOOLEAN.

IF msgtab EQ 'X'. "If error occured

IF item_carrid NE 'AA'.

use this REPORT_ERROR_MESSAGE.

ENDIF.

ELSE.

write your code here.

ENDIF.

Or

When ever the mandatory fields are not filled usually the system itself will hanlde the errors right.

yes that is what i was thinking that it sholud handle the error by itself. But it is not doing that. I think i have to do it by checking the initial condition for all the fields. Thanks any ways........

Pranav, you just have to call this method in WDDOBEFOREACTION method, with no parameters but the view controller API reference (assuming you got it previously with wd_this->wd_get_api( 😞

        cl_wd_dynamic_tool=>check_mandatory_attr_on_view(
          EXPORTING
            view_controller  = wd_this->view_controller_api
        ).

This will issue a generic message for each uncompleted Required field.

If the event handler (ONACTION*) is still executing, you can stop it by adding the following code at the top of it:

  DATA: lr_msg_man  TYPE REF TO if_wd_message_manager.

  lr_msg_man = wd_this->view_controller_api->get_message_manager( ).
  CHECK lr_msg_man->is_empty( ) = abap_true.

Hope this helps.
