ABAP code example for Function Module CHANGE_RESERVATION





The ABAP code below is a full code listing to execute function module CHANGE_RESERVATION 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).

ld_e_cancel  TYPE BOOLE-BOOLE ,
ld_e_restart  TYPE TRWF_STRUC-WF_RESTART .


SELECT single BELNR
FROM KBLK
INTO @DATA(ld_i_belnr).


SELECT single BLPOS
FROM KBLP
INTO @DATA(ld_i_blpos).
. CALL FUNCTION 'CHANGE_RESERVATION' EXPORTING i_belnr = ld_i_belnr * i_blpos = ld_i_blpos IMPORTING e_cancel = ld_e_cancel e_restart = ld_e_restart EXCEPTIONS NOT_FOUND = 1 . " CHANGE_RESERVATION

ABAP code to compare 7.40 inline data declaration with original syntax

The below ABAP code uses the older none in-line data declarations. This allows you to see the coding differences/benefits of the later inline 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_e_cancel  TYPE BOOLE-BOOLE ,
ld_i_belnr  TYPE KBLK-BELNR ,
ld_e_restart  TYPE TRWF_STRUC-WF_RESTART ,
ld_i_blpos  TYPE KBLP-BLPOS .


SELECT single BELNR
FROM KBLK
INTO ld_i_belnr.


SELECT single BLPOS
FROM KBLP
INTO ld_i_blpos.
