ABAP code example for Function Module WAHDC_READ_CUSTOMIZING

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

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_s_twahd
 
 TYPE TWAHD ,
ld_i_werks
 
 TYPE T001W-WERKS ,
ld_e_s_twdrd
 
 TYPE TWDRD ,
ld_i_matnr
 
 TYPE MARA-MATNR ,
ld_i_dismm
 
 TYPE T438A-DISMM ,
ld_i_read_drdprf
 
 TYPE C .



SELECT single WERKS 
  FROM T001W 
  INTO ld_i_werks.


SELECT single MATNR 
  FROM MARA 
  INTO ld_i_matnr.


SELECT single DISMM
