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_i_confirmation
 
 TYPE STRING ,
it_it_difference
 
 TYPE STANDARD TABLE OF STRING ,
wa_it_difference
 
 LIKE LINE OF it_it_difference,
ld_i_creator
 
 TYPE WFSYST-AGENT ,
ld_i_creation_date
 
 TYPE WFSYST-START_DATE ,
ld_i_creation_time
 
 TYPE WFSYST-START_TIME ,
ld_i_wiid
 
 TYPE SWWWIHEAD-WI_ID .


ld_i_confirmation = 'some text here'. 

"populate fields of struture and append to itab
append wa_it_difference to it_it_difference.

ld_i_creator = some text here

ld_i_creation_date = 20210129

ld_i_creation_time = Check type of data required

SELECT single WI_ID 
  FROM SWWWIHEAD
