program

Here is an example of a

report that shows all active

users

REPORT zws_call.

DATA: lr_proxy TYPE REF TO zws_co_z_get_active_useDATA: o_err TYPE REF TO cx_root.DATA: outputTYPE zws_zws_users_response.

DATA: inputTYPE zws_zws_users.DATA: ls_item TYPE LINE OF zws_zws_users_response-

TRY.CREATE OBJECT lr_proxyEXPORTINGlogical_port_name = 'GET_USERS'.

CATCH cx_ai_system_fault INTO o_err.MESSAGE o_err TYPE 'I'.

ENDTRY.input-rfc_only = space.TRY.

CALL METHOD lr_proxy->zws_usersEXPORTING

input = inputIMPORTINGoutput = output.

CATCH cx_ai_system_fault INTO o_err.MESSAGE o_err TYPE 'I'.CATCH cx_ai_application_fault INTO o_err.MESSAGE o_err TYPE 'I'.

ENDTRY.

LOOP AT output-users-item INTO ls_item.WRITE: / ls_item-bname, ls_item-tcode, ls_item-tENDLOOP.
