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_bukrs
 
 TYPE BSID-BUKRS ,
it_t_postab
 
 TYPE STANDARD TABLE OF RFPOS ,
wa_t_postab
 
 LIKE LINE OF it_t_postab,
ld_kunnr
 
 TYPE BSID-KUNNR ,
ld_kkber
 
 TYPE STRING ,
ld_stida
 
 TYPE RFPOSV-STIDA .



SELECT single BUKRS 
  FROM BSID 
  INTO ld_bukrs.
 

"populate fields of struture and append to itab
append wa_t_postab to it_t_postab.

SELECT single KUNNR 
  FROM BSID 
  INTO ld_kunnr.

ld_kkber = 'some text here'.

ld_stida = 20210129
