ABAP code example for Function Module ABL_MOVE_REQUIRED_LENGTH


The ABAP code below is a full code listing to execute function module ABL_MOVE_REQUIRED_LENGTH including all data declarations. The code uses the latest in-line data declaration syntax but I have included an abap code snipet 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).
DATA:
ld_destlen   TYPE RSEX2IN-LENGTH.


DATA(ld_srctype). = 'some text here'

DATA(ld_srclen). = 123

DATA(ld_srcdecs). = 123 . CALL FUNCTION 'ABL_MOVE_REQUIRED_LENGTH' EXPORTING srctype = ld_srctype * srclen = ld_srclen * srcdecs = ld_srcdecs IMPORTING destlen = ld_destlen EXCEPTIONS ILLEGAL_TYPE = 1 ILLEGAL_LEN = 2 ILLEGAL_DECS = 3 . " ABL_MOVE_REQUIRED_LENGTH
IF SY-SUBRC EQ 0.   "All OK ELSEIF SY-SUBRC EQ 1. "Exception   "Add code for exception here ELSEIF SY-SUBRC EQ 2. "Exception   "Add code for exception here ELSEIF SY-SUBRC EQ 3. "Exception   "Add code for exception here ENDIF.

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_destlen TYPE RSEX2IN-LENGTH ,
ld_srctype TYPE RSEX2IN-TYPE ,
ld_srclen TYPE RSEX2IN-LENGTH ,
ld_srcdecs TYPE RSEX2IN-DECIMALS .


DATA(ld_destlen). = 123

DATA(ld_srctype). = 'some text here'

DATA(ld_srclen). = 123

DATA(ld_srcdecs). = 123 .
