Add "filters" in non-ALV webdynpro TABLE

[Former Member]

Hi, We often run into the requirements where we are using TABLE UI element (without using SALV_WD_TABLE) in the webdynpro view to display the output and we need filters to cut down the data which is being displayed on the output. Hence this requirement generally consists of 2 things-

- Achieving filters on the table UI element (Table columns which are being displayed in the output)

- Read the filtered(shortened) contents of the node.

For the above requirements we make use of below steps to achieve-

- Achieving filters on the table UI element (Table columns which are being displayed in the output)

1. Create one attribute TAB_HANDLER of type IF_WD_TABLE_METHOD_HNDL in the main view—

Refer - SC_1(Attachment)

2. Go to WDDOMODIFYVIEW to get this attribute instantiated

method WDDOMODIFYVIEW .
DATA: lr_table TYPE REF TO cl_wd_table.
IF first_time = abap_true.
lr_table ?= view->get_element( 'OUTPUT_TABLE' ). "Here OUTPUT_TABLE is Table UI element name
wd_this->tab_handler ?= lr_table->_method_handler.
ENDIF.
endmethod.

3. Create one more node at context with name TAB_FILTERS—

Refer - SC_2(Attachment)

Enter>>

Refer - SC_3(Attachment)

Add attributes (these attributes must be same as the fields on which the filter is needed). Let us put filter on Flight number>>

Refer - SC_4(Attachment)

4. Goto Layout tab>> expand TABLE UI element >>Select the column on which the filter is needed>>

Refer - SC_5(Attachment)

Click on binding of filtervalue attribute>>

Refer - SC_6(Attachment)

Also, check IsFiltered property of the table column tooà

Refer - SC_7(Attachment)

5. Click on the Table UI element and create on event handler on Filter event

Refer - SC_8(Attachment)

6. Write below code to get this working—

wd_this->tab_handler->apply_filter( ).

Activate and refresh/start browser to see—

Refer - SC_9(Attachment)

Important notes

To reset filter, we must initialize the filter node attributes to ‘*’ if it is a character field and then we must call method APPLY_FILTER –

wd_this->tab_handler->apply_filter( ).

- Read the filtered(shortened) contents of the node.

To get the filtered data (which might be same / less data after we apply a filter) we can get using GET_TABLE_DATA method of the IF_WD_TABLE_METHOD_HNDL interface. This interface returns element references and we can use them in a loop to get the values using GET_STATIC_ATTRIBUTES method of IF_WD_CONTEXT_ELEMENT ‘s method.
