RETURN
Short Reference
ABAP Syntax RETURN.
What does it do? This statement ends the current processing block
immediately. It can appear at any point in a
processing block and ends this block
irrespective of the statement block or control structure in which the
block appears.
After the processing block is exited, the runtime environment responds
in the same way as when the processing
block is exited in a regular way (with the exception of
LOAD-OF-PROGRAM and the
reporting event blocks
START-OF-SELECTION and GET ). In particular, the output
parameters of procedures are passed on to the bound actual parameters.
You cannot exit the LOAD-OF-PROGRAM event block using
RETURN .
After the reporting event block START-OF-SELECTION is exited
using RETURN , the runtime environment does not trigger any more
reporting events; instead, it calls the list processor directly to
display the basic list.
After the reporting event block GET is exited using RETURN
, subordinate nodes in the hierarchical structure of the linked
logical database are no longer
processed. The logical database reads the next line of the current node
or next higher node, if it has reached the end of the hierarchy level.
ABAP_PGL Only use RETURN to
exit procedures
Latest notes: The RETURN statement is provided for exiting
processing blocks early but correctly. However, since RETURN
behaves differently in GET events than when the
event block is exited as usual, you should instead use the
REJECT statement there, which has
been designed especially for this purpose.
Example ABAP Coding Leave the method show_list with RETURN if
one of the formal parameters required ( structure or data_tab
) is initial.
METHOD show_list.
"IMPORTING structure TYPE c
" data_tab TYPE ANY TABLE.
DATA alv_list TYPE REF TO cl_gui_alv_grid.
IF structure IS INITIAL OR
data_tab IS INITIAL.
RETURN.
ENDIF.
CREATE OBJECT alv_list
EXPORTING i_parent = cl_gui_container=>screen0.
alv_list->set_table_for_first_display(
EXPORTING i_structure_name = structure
CHANGING it_outtab = data_tab ).
CALL SCREEN 100.
ENDMETHOD.
