The main use of this blog is to understand the passing of values from a Webdynpro application to another Webdynpro application.

We have created two Webdynpro applications say A and B. A is the calling application and B is the called application. Both A and B has one common attribute which is necessary for link between them (like SO number is common between these two applications).

After any event on application A, application B should start in a new window.
For this, we have to write this pseudo code in the event method of application A.

Pseudo code in application A:

First we need URL of the application B. Store this value in a string type variable say lv_url.

call method cl_wd_utilities=>construct_wd_url
exporting
application_name = ‘B’
importing
out_absolute_url = lv_url.

Attach the parameters and its value with the URL that have to be passed to the 2nd application

call method cl_http_server=>append_field_url
exporting
name = * Name of the field
value = *Value of the field
changing
url = lv_url.

After doing this, we have to create a popup window which shows application B. This can be achieved by using following code template.

DATA lo_window_manager TYPE REF TO if_wd_window_manager.
DATA lo_api_component TYPE REF TO if_wd_component.
DATA lo_window TYPE REF TO if_wd_window.

lo_api_component = wd_comp_controller->wd_get_api( ).
lo_window_manager = lo_api_component->get_window_manager( ).
lo_window = lo_window_manager->create_external_window( url = lv_url ).
lo_window->open( ).

Pseudo code in application B:

In this application, we have to receive the value send by Application A and select the records based on this value. For this, we have to write code in WDDOINIT method in application B.

*We have to define a variable which stores value coming from application A.

Data: lv_value type String.
lv_value = wdr_task=>client_window->get_parameter( ‘Name_of_the_Field’ ).

After getting the value in the lr_value field, we can select records based on this value and bind the internal table by using method bind table for displaying records.

    Hi Saleem,

    Thanks for sharing information.

    For getting URL parameters it would be better to use:

    lv_value = cl_wd_runtime_services=>get_url_parameter( name = ‘Name_of_the_Field’ ).

    Regards,
