ABAP - Split container with dynamic heading

[Former Member]

Hi All,

I created a 2 custom containers one for Heading and the other for displaying data as below . For displaying the header content I created a reference variable HEAD1 of the class CL_DD_DOCUMENT. Later i build the content of the content of the header using method ADD_TABLE and displayed the header using MERGE and DISPLAY_DOCUMENT and placed in the custom container HEADING1.

Now my issue is i want to change the content of the header dynamically based on the PUSH button but using the same code. Means i want to display different content inthe header when i toggle a push button in the previous screen .I even refreshed the reference varaible once i come back ftom this screen. But the content is not getting refreshed. I am making a major mistake somewhere. Please help to corect this.

  HEADING1 TYPE REF TO CL_GUI_CUSTOM_CONTAINER,

  CUSTOM_CONTAINER1 TYPE REF TO CL_GUI_CUSTOM_CONTAINER,

  HEAD1 TYPE REF TO CL_DD_DOCUMENT,

  CALL METHOD HEAD1->ADD_TABLE

  CALL METHOD HEAD1->MERGE_DOCUMENT.
 

  CALL METHOD HEAD1->DISPLAY_DOCUMENT
      EXPORTING
        CONTAINER = 'HEADING1'.

Hi Siva,

I had exactly the same situation today in the morning and I have done 2 mistakes.

a.) If you use the coding inside an own class method you have to declare the head1 as an class attribute and not inside the method as a local object reference

The coding for this part in my method is now:

   IF mr_dd_document IS NOT BOUND.
    CREATE OBJECT mr_dd_document.
  ELSE.
    mr_dd_document->initialize_document( ).
  ENDIF.

  ....... "here is then the coding to add a table, put in text, icons, pictures and so on

"and finally
  CALL METHOD mr_dd_document->MERGE_DOCUMENT.
  CALL METHOD mr_dd_document->DISPLAY_DOCUMENT
      EXPORTING
        CONTAINER = 'HEADING1'.

b.) that the above coding works also for a refresh I had to change the coding with
     additionial the EXPORTING parameter reuse_control = 'X'

     (I call my method in the same way independend if it is for first display or a refresh and I store the  container inside the class attribute mr_container )

    "merge the new document
  CALL METHOD mr_dd_document->merge_document.
  lv_container_nam = mr_container->get_name( ).
  lv_container_name = lv_container_nam.
  "display the new document in the container
  CALL METHOD mr_dd_document->display_document
    EXPORTING
      reuse_control      = 'X'
      reuse_registration = 'X'
      container          = lv_container_name
      parent             = mr_container
    EXCEPTIONS
      html_display_error = 1.
