ABAP code example for Function Module RRT_MATH_SUM

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

DATA:
ld_e_sum  
 
 TYPE RRT3_NUM_VALUE
.


DATA(ld_c_t_val) = 'Check type of data required'.
.

CALL FUNCTION 'RRT_MATH_SUM'
  IMPORTING
    e_sum =                      ld_e_sum
  CHANGING
    c_t_val =                    ld_c_t_val
    .  "  RRT_MATH_SUM

IF SY-SUBRC EQ 0.
  "All OK
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_c_t_val
 
 TYPE RRT3_TA_VAL ,
ld_e_sum
 
 TYPE RRT3_NUM_VALUE .


ld_c_t_val = 'Check type of data required'.
