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_no_authority
 
 TYPE STRING ,
ld_no_authority
 
 TYPE STRING ,

ld_message_type_imp
 
 TYPE SY-MSGTY ,
ld_tcode_imp
 
 TYPE SY-TCODE ,
ld_trtyp_imp
 
 TYPE TCA05-TRTYP .



SELECT single PLNAW 
  FROM TCA01 
  INTO ld_plnaw_imp.

ld_plkod_imp = 'some text here'.
