ABAP code example for Function Module QUANTITY_COMPARISON

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

 

SELECT single MSEHI 
  FROM T006 
  INTO @DATA(ld_meinh_gr).

 

SELECT single MSEHI 
  FROM T006 
  INTO @DATA(ld_meinh_kl).


DATA(ld_wert_gr) = 'some text here'.

DATA(ld_wert_kl) = 'some text here'.
.

CALL FUNCTION 'QUANTITY_COMPARISON'
  EXPORTING
    meinh_gr =                   ld_meinh_gr
    meinh_kl =                   ld_meinh_kl
*   wert_gr =                    ld_wert_gr
*   wert_kl =                    ld_wert_kl

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_meinh_gr
 
 TYPE T006-MSEHI ,
ld_meinh_kl
 
 TYPE T006-MSEHI ,
ld_wert_gr
 
 TYPE STRING ,
ld_wert_kl
 
 TYPE STRING .



SELECT single MSEHI 
  FROM T006 
  INTO ld_meinh_gr.


SELECT single MSEHI 
  FROM T006 
  INTO ld_meinh_kl.

ld_wert_gr = 'some text here'.
ld_wert_kl = 'some text here'.
