Dynamic buttons in webdynpro

[Former Member]

Dear Experts,

Can anyone help me in creating buttons dynamically in webdypro?.

The scenario is " i have one webdynpro screen.In that, at requestor level-the requestor screen should contain only SAVE,DELETE buttons & at approval level-the approver sceen should contain only APPROVE & REJECT buttons.

Please help with any example code/documents/links which helps me achieve this functionality.

Thanks

1. Define attributes MR_FPM of type ref to IF_FPM  and MR_CNR of type ref to IF_FPM_CNR_OVP in component controller.

2.  Get the reference to the IF_FPM interface in WDDOINIT of COMPONENTCONTROLLER

   wd_this->mr_fpm = cl_fpm_factory=>get_instance( ).

3. Now in the WDDOMODIFYVIEW of your view check  the user is of  requester level or approver level and based on the condition define the required buttons like :

wd_comp_controller->mr_cnr ?= wd_comp_controller->mr_fpm->get_service( if_fpm_constants=>gc_service_key-cnr_ovp ).
   CALL METHOD wd_comp_controller->mr_cnr->define_button
     EXPORTING
       iv_variant_id     = 'YOUR_VARIANT_ID'
 *      iv_mainstep_id    = 'YOUR_MAIN_STEP_ID'
 **      iv_subvariant_id  = ''
 **      iv_substep_id     = ''
       iv_function       = if_fpm_constants=>gc_button-other_function
       iv_element_id     = 'SAVE'
 *      iv_sequence_id    = '0'
       iv_design         = '01'
       iv_enabled        = 'X'
 **      iv_explanation    = ''
 *      iv_on_action      = 'FPM_NEXT_STEP'
       iv_text           = 'YOUR BUTTON TEXT'
 *      iv_tooltip        = ''
 *      iv_visibility     = ''
 *      iv_default_button = ''
 *      iv_hotkey         = ''

If you are having the same view (screen) for requester and approver then you may create all the buttons ( SAVE,DELETE, APPROVE & REJECT ) in your view and based on the condition whether requester level or approver level you can hide the ones which you do not require.
