Access to Actions of a BEx Web Application 

Various actions can be executed in a Bex Web Application – for example, the filtering oder arranging of data in a table.

You can use the method handler of BIApplicationFrame from method WDDOMODIFYVIEW, for example:

method wddomodifyview.

 

data:

    lr_bi_control type ref to cl_wd_biapplication_frame,

    lr_container  type ref to cl_wd_uielement_container,

    lt_items      type string_table,

    lt_actions    type string_table.

 

* save the method handler

  check first_time = abap_true.

  lr_bi_control ?= view->get_element( 'BI_APPL_FRAME' ).

  wd_this->m_bi_method_handler ?= lr_bi_control->_method_handler.

 

Then you can also access the various methods in actions.

Application developers work with the interface IF_WD_BI_APPLFRAME_METHOD_HNDL only; classes are created automatically by Web Dynpro.
