Inline declaration is a feature introduced with ABAP 7.40 version. With this, when obtaining a value without declaring a variable beforehand, a variable of the type of the value to be obtained is automatically created. This is achieved using the syntax DATA(lv_variable).
Examples
Variables
The value keyword in ABAP is used when declaring data and assigning a default value. When you use value #(value), ABAP assigns a type that matches the value you provide within the value keyword. If you want to specify a particular type, you can use # instead of type.
data(lv_string) = |This is text|. "string
data(lv_date) = value datum( '20241796' ). "date
data(lv_integer) = value i( '1453' ). "integer
data(lv_boolean) = value abap_bool( 'X' ). "char
Loops
"data
loop lt_lines into data(ls_line).
"todo
endloop.
"field-symbol
loop lt_lines assign field-symbol(<fs_line>).
"todo
endloop.
