Calling the Mail Class 
You have now completed the mail class except for the method to read the mail text (GET_TEXT). This method reads the mail text and passes it to the caller in HTML format. In the following BSP you can display which mail is sent.
The methods are called only if no error has occurred during the input and if the mail address has been entered (page order.htm, event handler OnInputProcessing).
Syntax
if page->messages->num_messages( ) eq 0. if mail_address is not initial.
An instance of the class just created can be accessed under the attribute application everywhere in the page. The address can be set simply with:
Syntax
application->set_address( name = name street = street zipcode = zipcode city = city ).
Select the middle value from the earliest and latest times as the time point and then call method SET_TIME:
Syntax
data: time_when type t. time_when = time_from + ( time_to - time_from ) / 2. application->set_time( date = date_at time = time_when ).
The mail address and the message object (see Object Messages) is transferred for sending, so that error texts can be entered into the message list.
Syntax
call method application->send exporting mail_address = mail_address changing messages = page->messages .
If everything has been processed without errors, transfer the mail text to the next page (after you have created and filled the method in the class). There the text is displayed.
Syntax
if page->messages->num_messages( ) eq 0. data text type string. text = application->get_text( ). navigation->set_parameter( name = 'mailtext' value = text ). navigation->next_page( 'show' ). endif. else. navigation->next_page( 'no_address' ). endif. endif.
