The VALUE operator can be used to construct the content of complex data objects such as structures or internal tables.
It is particularly useful because assigning values by addressing the structure components individually can be very cumbersome, especially when assigning values to structure components at the operand position.
If the type of the operand can be inferred implicitly, the # character can be used used before the parentheses. Otherwise, the type must be specified explicitly.
The VALUE operator and inline declarations can be used to create and populate structures in one go.
Note that there are special conversion and comparison rules for structures. See the ABAP Keyword Documentation for more details.
"# used: type of the operand can be implicitly derived
address = VALUE #( name = `Mr. Duncan Pea`
street = `Vegetable Lane 11`
city = `349875 Botanica` ).
"Declaring a structure inline
"Type used explicitly: type of the operand cannot be implicitly derived
DATA(addr) = VALUE addr_struc( name = `Mr. Duncan Pea`
street = `Vegetable Lane 11`
city = `349875 Botanica` ).
"Using the BASE addition to retain existing component values
addr = VALUE #( BASE addr street = `Some Street 1` ).
*NAME STREET CITY
*Mr. Duncan Pea Some Street 1 349875 Botanica
"Without the BASE addition, the components are initialized
addr = VALUE #( street = `Another Street 2` ).
*NAME STREET CITY
* Another Street 2
