ABAP code example for Function Module TREX_DISPLAY_HOSTS_SELECTION





The ABAP code below is a full code listing to execute function module TREX_DISPLAY_HOSTS_SELECTION including all data declarations. The code uses the latest in-line data DECLARATION SYNTAX but I have included an ABAP code snippet at the end to show how declarations would look using the original method of declaring data variables up front. This will allow you to compare and fully understand the new inline method. Please note some of the newer syntax such as the @DATA is not available until a later 4.70 service pack (SP8).

ABAP code to compare 7.40 inline data declaration with original syntax

It may also be useful if you are using an older version of SAP as some of the newer syntax above, such as the @DATA is not available until 4.70 EHP 8.

DATA:
ld_host_selection  TYPE TREXT_SELECTION_LIST ,
ld_e_return_code  TYPE TREX_RFC-RETURN_CODE ,
ld_i_rfc_destination  TYPE TREX_RFC-RFC_DESTINATION ,
ld_e_return_text  TYPE TREX_RFC-RETURN_TEXT ,
ld_i_screen_start_column  TYPE I ,
ld_e_selected_hosts  TYPE TREX_RFC-LOCATION2 ,
ld_i_screen_start_line  TYPE I ,
ld_i_screen_end_column  TYPE I ,
ld_i_screen_end_line  TYPE I .

ld_host_selection = 'Check type of data required'.

ld_i_rfc_destination = some text here
