ALV Print Version header - Multiple lines

[Former Member]

Hi,

I am attempting to write multiple lines on the header of the Print Version of an ALV Web Dynpro grid. Basically, the aim is to be able display/print the selection criteria that was executed to produce the ALV report.

I have attempted two different techniques:

DATA: lr_pdf_settings TYPE REF TO if_salv_wd_pdf_settings,

lo_value TYPE REF TO cl_salv_wd_config_table,

lo_interfacecontroller TYPE REF TO iwci_salv_wd_table .

lo_interfacecontroller = wd_this->wd_cpifc_usage_alv( ).

lo_value = lo_interfacecontroller->get_model( ).

lr_pdf_settings ?= lo_value.

lr_pdf_settings->set_header_left( if_salv_wd_c_pdf_settings=>text_free ).

data: lv_header type string.

Technique 1:

move 'hello \n world' to lv_header.

Result: Only hello is displayed

Technique 2:

concatenate 'hello' 'world' to lv_header separated by cl_abap_char_utilities=>cr_lf.

Result: Nothing is displayed

lr_pdf_settings->set_header_left_freetext( lv_header ).

Please help. Also, I notice that this only works if the code is placed in the WDDOBEFOREACTION method of the view.

Any help is much appreciated.

TIA

I finally managed to do this. Code below:

DATA: lr_node TYPE REF TO if_wd_context_node,

lr_element TYPE REF TO if_wd_context_element,

lr_top_element TYPE REF TO cl_salv_form_layout_grid,

lr_grid TYPE REF TO cl_salv_form_layout_grid,

lr_header TYPE REF TO cl_salv_form_header_info,

lr_action TYPE REF TO cl_salv_form_action_info.

CREATE OBJECT lr_top_element

EXPORTING

columns = 1.

• DATA: lv_header TYPE string.

lr_header = lr_top_element->create_header_information(

row = 1

column = 1

text = 'My Title'

tooltip = 'List of Notifications' ).

lr_action = lr_top_element->create_action_information(

row = 2

column = 1

text = 'Selection parameters \r\n Client 500, Cost Center 500320'

tooltip = '' ).

lr_node = wd_context->get_child_node( name = 'TOP_OF_LIST' ).

lr_element = lr_node->get_element( index = 1 ).

CALL METHOD lr_element->set_attribute

EXPORTING

value = lr_top_element

name = 'CONTENT'.
