how to assign a WD value help to a UI field in FPM application

[former_member199252]

Hi Team,

In my FPM application for one UI field a DDIC search help is assigned . Now my requirement is , i have to assign a WD value help to that particular field. So whenever am clicking on F4 instead of that DDIC search help i want to show  WD value help.

I have tried to add the properties in GET_DEFINITION method , but its giving a dump saying that Assert Violation.

And also i have tried to implement the method CHANGE_FIELD_DEFINITION of  interface /PLMU/IF_FRW_G_FIELD_DEF.

But this method is not getting triggered.

Can anyone please suggest how to resolve this.

Hi Ramya,

I think your requirement is to change the f4 help.

You have to follow the below steps.

data lr_node_info type ref to if_Wd_Context_info.

1. Get the instance of the Node(if_wd_Context_node).

     lr_node = wd_context->get_Child_node('NODENAME').

2. Get the object of the lr_node_info.

lr_node_info  = lr_node->GET_NODE_INFO().

now you have the object of the if_Wd_Context_info.

call the method

call method lr_node_info->SET_ATTRIBUTE_VALUE_HELP()

give the value in the importing parameter and set the record.

Thanks

HI Ramya,

Check the below code for the same.

How you are generating the fieldcatalog.?

CL_FPM_GUIBB_TEST_VH_FORM.

method get_Defination.

FIELD-SYMBOLS:

      <ls_field_descr> LIKE LINE OF et_field_description.

   CALL METHOD mo_meta_data->get_definition

     IMPORTING

       et_field_description = et_field_description

       et_action_definition = et_action_definition

       et_special_groups    = et_special_groups.

   eo_field_catalog = mo_meta_data->mo_struct_rtti.

   LOOP AT et_field_description ASSIGNING <ls_field_descr>.

     CASE <ls_field_descr>-name.

       WHEN 'CONNECTOR'.

         <ls_field_descr>-wd_value_help = 'FPM_TEST_VH'.

     ENDCASE.

   ENDLOOP.

Thanks

Hi Nishant,

I am building the field catalog in get_definition method by using below statement.

EO_FIELD_CATALOG ?= CL_ABAP_TABLEDESCR=>DESCRIBE_BY_DATA( LV_ORDER ).

the class you mentioned in the above reply CL_FPM_GUIBB_TEST_VH_FORM is a final class so can you please tell me clearly how can i build field catalog with this class.
