ABAP code example for Function Module CF_CK_FHWRK

The ABAP code below is a full code listing to execute function module CF_CK_FHWRK 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_name1_exp
 
 TYPE T001W-NAME1 ,
ld_fhwrk_imp
 
 TYPE T001W-WERKS ,
ld_name2_exp
 
 TYPE T001W-NAME2 ,
ld_fhwrk_not_initial_imp
 
 TYPE STRING ,
ld_t001w_exp
 
 TYPE T001W ,
ld_msgty_imp
 
 TYPE SY-MSGTY .



SELECT single WERKS 
  FROM T001W 
  INTO ld_fhwrk_imp.

ld_fhwrk_not_initial_imp = 'some text here'.
ld_msgty_imp = 'some text here'.
